2  
3 + 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 +   with a Firebrid 3 client library.
5  
6 < 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
7 <   and is used to override the default settings in the client side "firebird.conf" This
8 <   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
9 <   Each line of the string list should be a setting in the same format as "firebird.conf".
10 <   For example "WireCompression = true" in order to request wire compression on the client side.
6 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
7 >    If a client library path is not explicitly provided and the FIREBIRD environment
8 >    variable is set then the directory given by this variable and any 'lib' subdirectory
9 >    are searched for the Firebird client library. Only if none is found, is the default
10 >    client library used.
11  
12 <   Note: explicit settings in the client side "firebird.conf" appear to take precedence
11 <   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
12 <   also require a compatible setting in the server side "firebird.conf". For example
13 <   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
14 <   compression to be used.
12 > 3.  IUtil.FormatStatus now used to format error messages when using new API
13  
14 <   Whether or not WireCompression or WireCrypt are in use can be checked using the information
17 <   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
18 <   ibx/examples/dbinfo for examples of how to display this information.
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
15  
16 < 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
17 <   is a "convenience" property. If set the "WireCompression=true" is added to the
18 <   ConfigOverrides. If unchecked then this setting is removed.
16 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
17 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
18 >    that the byte length corresponds to the number of characters specified for the column.
19 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
20 >    correct behaviour but may affect some implementations that relied upon automatic
21 >    trimming of trailing white space.
22  
23 < 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
24 <   not "INT64".
23 > 6.  New IFirebirdAPI Calls:
24 >      function GetClientMajor: integer;
25 >      function GetClientMinor: integer;
26  
27 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
28   These are:
29    property TimestampFormat: string;
30    property DateFormat: string;
31    property TimeFormat: string;
27  
28 <   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
34 <   DATETIME and TIME. The format strings use the standard FPC date/time format
35 <   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
28 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
29  
30 <   If any of the above properties are set to an empty string, then the locale default
31 <   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
39 <   locale default is extended by appending '.zzz' to include milliseconds.
30 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 >   case sensitive
32  
33 <   TIBCSVDataOut by default sets these properties to the empty string, while the other
42 <   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
33 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
34  
35 < 5. New published property for TIBCSVDataOut:
36 <     property QuoteStrings: boolean (default true)
35 > 3. New API Calls:
36 >        IColumnMetaData.GetStatement
37 >        IColumnMetaData.GetTransaction
38 >        ISQLData.GetStrLength
39 >        IResults.GetStatement
40 >        IAttachment.OpenBlob (using Blob metadata)
41 >        IAttachment.OpenArray (using array metadata)
42  
43 <   If false then strings are unquoted, otherwise, the QuoteChar property value is
48 <   used to delimit each and every string in the output.
43 > 4. FBMessages: removal of unused messages
44  
45 < 6. New published properties for TIBCSVDataOut:
51 <    property FieldSeparator: string;
52 <    property HeaderSeparator: string;
45 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
46  
47 <   Respectively, these provide the separator character(s) used to separate fields
55 <   in data and header rows. Both default to ','.
47 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
48  
49 < 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
58 <    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
59 <    property OnFormatTextString;
49 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
50  
51 <   This event handler can be used to process text strings before they are included
52 <   in the output e.g. to replace unprintable characters with alternative strings.
63 <   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
51 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
52 >   where the second character of the parameter name is a numeric.
53  
54 < 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
55 <   Uses "FindParam" if in order to find out if a parameter with a given name exists
56 <   and without raising and exception if it does not.
54 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
55 >   This returns the isc_version connection information as one or more lines.
56 >   This is the same information as returned by isql with the -z option.
57  
58 < 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
59 <   consistency with SQL queries.
58 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
59 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
60 >   compiler option then the Firebird 3 API is no longer compiled in.
61  
62 < 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
73 <    When true, SQL statement parameter names are parsed case sensitive. Note for
74 <    TIBDataSet only applies to Select query.
62 > 4. IColumnMetaData: new method.
63  
64 < 11. IBEvents: removing a TIBEvent component from a form should no longer result in
65 <    an IDE exception.
64 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 >                        dfDateTime,   {SQL DATETIME}
66 >                        dfTime);
67  
68 < 12. LocalDBSupport: initial database creation should now work correctly
80 <    when the schema source is an sql file.
68 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
69  
70 < 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
71 <    when defined, this handler will be called by the internal TIBXScript during
84 <    initial database creation when the schema source is an sql file and may be used
85 <    to provide a visual indication of progress in console mode.
70 >   This returns the max. number of characters returned by the "AsString" method
71 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
72  
73 < 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
74 <    to true while a new local database is being created and its schema populated.
89 <    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
90 <    when the database is disconnected/connected during the create DB procedure.
73 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
74 >     CaseSensitiveParams: boolean = false
75  
76 < 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
77 <    are now always ignored and replaced by the user name and password provided as
78 <    the login parameters for the TIBDatabase referenced from the TIBXScript. The
95 <    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
96 <    completely ignored if this property is true.
76 >   If this argument is set to true then SQL parameter names are assumed to be case
77 >   sensitive and must be referenced (using ISQLParams.ByName) using the case
78 >   sensitive name.
79  
80 < 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
81 <    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
82 <    ImageIndex and SelectImageIndex values on AddNode.
80 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
81 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
82 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
83 >   using .AsString.
84  
102 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
103    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
104    the same database connection.
85  
106 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
107    if provided, this should be an conditional SQL expression suitable for
108    including in an SQL Select statement "where" clause. If non-empty and the
109    "Filtered" property is true then the SQL expression provided as the value of
110    the "Filter" property is "ANDed" with any existing condition statement
111    in the SQL statement's "Where" clause.
86  
87 <    If the "Filter" property is set at run time, the "Filtered" property is true
114 <    and the dataset is already open, then the dataset is closed and re-opened automatically.
87 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
88  
89 <    The "Filter" condition may include IBX style parameters. In which case, their
117 <    value must be set by the dataset's "OnBeforeOpen" event handler.
89 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
90  
91 <    This is a public property for TIBDataSet and TIBQuery query and intended for
92 <    use at run time.
91 > 2. Restrict IsMultiThread check to Unix only for compatibility with
92 >   https://bugs.freepascal.org/view.php?id=30535
93  
94 <    Note: The property is a published property of TIBTable. The TIBTable functionality
95 <    is unaffected by this change.
94 > 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
95 >   named parameters and is intended to avoid problems with (e.g.) Execute Block
96 >   and processing internal parameters as statement parameters.
97  
98 < IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
98 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
99 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
100  
101 < 1. Remove need to check for IsMultiThread by providing access to GUI timers via
128 <   IBGUIInterface. Note: master/detail delay timer does not apply to console
129 <   mode apps.
101 > 5. New function added to IB.pas
102  
103 < 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
132 <   statement. This avoids problems if "Execute Block" is used as the Query.
103 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
104  
105 < 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
106 <   internal SQL tokeniser routines.
105 >   This allows a Firebird Library to be loaded from an explicit path. use the
106 >   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
107 >   the library. It is possible to load Firebird libraries from different locations
108 >   simultaneously, each with a distinct IFirebirdAPI.
109  
110 < 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
138 <   as a select statement, with or without CTEs.
110 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
111  
112 < 5. IBSQLParser: parser now recognises the "ROWS" clause.
112 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113 >   program compiled with -CR command line switch.
114  
115 < 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
116 <   internal SQL tokeniser routines.
115 > 2. IServiceManager additions (informational):
116 >    function getProtocol: TProtocol;
117 >    function getPortNo: AnsiString;
118  
119 < 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
120 <    being raised for valid set statements processed by a data formatter.
119 > 3. IServiceManager improved error handling. Interfaces changed:
120 >    function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
121 >    function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
122 >    function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
123  
124 < 8. New published property for TIBDatabase and TIBXServicesConnection. This is
125 <   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
150 <   the path of the Firebird Library used by the database/services connection.
124 > 4. IAttachment addition (informational)
125 >    function GetSecurityDatabase: AnsiString;
126  
127 < 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
128 <   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
129 <   services connection.
127 > 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
128 >   thus now returns accumulated stats for a select statement from opening a cursor
129 >   up to the last fetch.
130  
131 < 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
132 <   or param name is not a valid SQL identifier.
131 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
132 >   the problem.
133  
134 < 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
135 <    view of whether the text box should be editable when no DataSource is specified.
161 <    TIBLookupComboEditBox has been updated to workaround this problem. As long as
162 <    ReadOnly is false, the text box is editable when no DataSource is specified.
134 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 >   replaces deprecated "comp" type.
136  
137 < 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
165 <    the FBLIB environment variable. If you do not want to permit this then you
166 <    must modify the Register procedure in the design/IBDBReg.pas unit to remove
167 <    this setting.
137 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
138  
139 < IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
139 > 11. URL Connection Strings: inet4 and inet6 now recognised.
140  
141 < 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
172 <   Utf8EscapeControlChars
141 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
142  
143 < IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
143 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
144  
176 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
177 all previous copies of the IBX source code tree before installing this release.
145  
146 < The IBX packages used by most users have not changed, with one exception. The
180 < IBServices unit has been moved to the package iblegacyServices.lpk. To continue
181 < to use the IBServices unit in your applications, please add the iblegacyServices
182 < to the list of dependencies. To do this, open the Project Inspector and select
183 < Add->New Requirement and select "ibLegacyServices" from the list of available
184 < packages.
146 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
147  
148 < 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
187 <   the IBServices unit providing what is intended to be a clearer and easier to
188 <   use set of IB Services components. See Chapter 10 of the IBX User Guide for
189 <   more information and the guide to "Firebird Service Management Using IBX".
190 <   As indicated above, the legacy services components are still available and
191 <   provided in a separate package. There is no need to update working applications
192 <   using the older versions except for an additional package dependency.
148 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
149  
150 < 2. The IBX packages and source code tree have been re-organised in an attempt to
151 <   finally get rid of the "duplicate ppu" warnings. This re-organisation should
152 <   not affect existing users. Section 2.3 of the IBX User Guide describes the
197 <   new set of IBX packages.
150 > 2. IAttachment: add two new methods
151 >     function HasDefaultCharSet: boolean;
152 >     function GetDefaultCharSetID: integer;
153  
154 < 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
155 <   updated to use the new Services API components.
154 >   These return, respectively, true if a connection default character set was
155 >   specified and the character set id of the connection default character set.
156 >   The DefaultCharSetID is cached when the connection is opened and hence does not
157 >   require a database lookup.
158  
159 < 4. The iblocal package has been updated to use the new Services API components.
159 > 3. Avoid exception when a text blob is a stored procedure parameter.
160  
161 < 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
205 <   TIBXSecurityService. It had been wrongly classified in the previous version
206 <   as a per database configuration item. It is global to a server and hence
207 <   correctly positioned as part of the Security Package. In the DBAdmin example,
208 <   the setting has moved to the mappings page.
161 > 4. Update test suite to include a test for a stored proc returning a text blob.
162  
163 < 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
164 <   are ignored.
163 > 5. IAttachment: add
164 >      function GetRemoteProtocol: AnsiString;
165 >      function GetODSMajorVersion: integer;
166 >      function GetODSMinorVersion: integer;
167 >      function GetAuthenticationMethod: AnsiString;
168  
169 < 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
170 <   closed before the database is dropped. Before and After Disconnect event handlers
215 <   are also fired.
169 >   These results are cached when the connection is opened and hence do not
170 >   require a database lookup.
171  
172 < 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
173 <   is started and not just the first time.
172 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 >   connect string used to create/connect to the database.
174  
175 < 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
176 <   depenendency with comp type.
175 > 7. IAttachment: Create Database using SQL statement. The username and password
176 >   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
177 >   It is now possible to use IAttachment disconnect/connect to reconnect to
178 >   a database for which the initial connection was established by a create
179 >   database sql statement. Available in FPC only.
180  
181 < 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
181 > 8. Update Test 1 to test 5, 6 and 7 above.
182  
183 < 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
226 <    then this is recognised and not ignored.
183 > 9. IBUtils code tidy up.
184  
185 < 12. TIBDataSet, TIBQuery, TIBTable: additions:
186 <    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
187 <    function GetPerfStatistics(var stats: TPerfCounters): boolean;
188 <    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
185 > 10. Parameter Block interfaces "find" method. As documented, this should have
186 >   returned a nil interface when the item could not be found. Instead, an empty
187 >   interface item was returned. "Find" now works as documented and will return
188 >   a nil interface if the item cannot be found.
189  
190 <    GetRowsAffected returns the affected row counts from the last insert/update/delete
234 <    if EnableStatistics = true then GetPerfStatistics returns the current stats
235 <    counters for the select query. Note: stats accumulate after each fetch from
236 <    the database. To get total query cost after open, call the "Last" method
237 <    and then GetPerfStatistics.
190 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
191  
192 <    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
192 > 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
193 >    requests with additional parameters. This is to enable support for fb_info_page_contents
194 >    (return of page contents). Response to fb_info_page_contents returned as
195 >    a string with code page CP_NONE.
196  
197 < 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
198 <    in parenthesises.
197 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 >    test suite updated.
199  
200 < 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
201 <    SQL identifiers are always delimited by double quotes. If false, then they are
246 <    only delimited if the identifier is a reserved word, contains lower case or special
247 <    characters. Set this property to true to retain previous behaviour.
200 > 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
201 >    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
202  
203 < 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
204 <    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
203 > 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
204 >    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
205 >    default connection port to be specified.
206  
207 < 16. TIBDataSet, TIBQuery, TIBTable: addition:
253 <       property MasterDetailDelay: integer {defaults to zero}

209 <    When non-zero and the dataset is a detail table referencing a master table
210 <    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
257 <    then a synchronisation delay is added (in milliseconds) between the master
258 <    row changing and the detail dataset being re-opened. If the master dataset
259 <    is scrolled before the delay expires then the delay is reset. This can be used
260 <    to avoid performance overheads when scrolling through a large master dataset.
209 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 >   Scale is no longer ignored.
211  
212 <    Note: uses fptimer and hence requires a thread manager. Under Linux the
213 <    chreads unit must be included in your project. TTimer is not used in order
214 <    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
212 > 2. Fix issues with setting SQL Param values using SetAsString with Date values
213 >   not in locale format but which are recognised by Firebird. Date values that
214 >   cannot be converted to a string using Pascal library are now passed through
215 >   to Firebird as Text Strings.
216  
217 < 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
218 <    with Extract Option eoDatabase.
217 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
218 >   UTF8 and not UNICODE_FSS.
219  
220 < 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
221 <    When a deLayoutChanged event is reported on the ListSource dataset, the
222 <    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
223 <    relationship with the control's datasource (master).
220 > 4. Charset ID problem. When using Firebird 3, with no default database character set
221 >   and a column has a non-default collation specified, an incorrect character set
222 >   id was being reported that could result in a 'division by zero' error when
223 >   used by IBX. This has now been fixed.
224  
225 < 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
225 > 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
226 >   CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
227 >   the character sets supported can be updated on a per database basis. That is
228 >   it is possible to add a (Firebird) user defined character set to a database.
229  
230 < 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
231 <    stubs. Pedantic fix really, as procedures output in dependency order anyway.
230 > 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
231 >   set supported by Firebird with the API.
232  
233 < 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
234 <    DDL (Firebird 3 and later only).
233 > 7. Add missing isc_info_db_read_only to list of decoded Database Information items
234 >   in FBOutputBlock.pas and update test suite to include this item.
235  
236 < 22. TIBLookupComboBox Autocomplete Fixes:
283 <    i. Only appended text is now selected after autocomplete.
284 <    ii. Uppercase keys no longer ignored for autocomplete.
285 <    iii. Retain Prefix case is now honoured correctly.
286 <    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
287 <        before autocomplete performed. i.e. behaviour now the same as when
288 <        no DataSource assigned.
236 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
237  
238 < 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
239 <    between SQL statements.
238 > 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
239 >   library or finding it by disk location, the PATH environment variable is now also set to
240 >   include the FIREBIRD directory. This is to ensure that the correct dlls in the
241 >   firebird client library dependencies are loaded.
242  
243 < 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
294 <    ObjectNames are converted to upper case before matching against metadata object
295 <    names, unless the objectname is delimited by double quotes, in which case, the
296 <    double quotes are removed and the remaining string is used (unmodified) to match
297 <    against the metadata object name.
243 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
244  
245 <    If true then the ObjectName is used as is without modification and matched
300 <    against the metadata object name. No attempt is made to remove double quotes.
245 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
246  
247 < 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
303 <    with eoTrigger, these extract types can be used to select only Database Triggers,
304 <    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
247 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
248  
249 < 26. TIBXScript: If an exception occurs during the processing of a statement, the
250 <    statement separate character is now reset to the default (';').
249 > 13. FB30Statement: A check has been added to ensure that all SQL Parameters
250 >    have been given a value (including NULL). Previously, failing to set the
251 >    value of an SQL Parameter could give rise to unpredictable results or
252 >    an SQLDA error.
253  
254 < 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
254 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
255  
256 < 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
257 <    a commit or reconnect statement and instead activated only when next SQL statement
313 <    is executed.
256 > 15. FBAttachment: Avoid string reference count error when processing an Ansistring
257 >    parameter in an array of const passed to IAttachment.OpenCursor, etc.
258  
259 < 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
259 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260 >    of const passed to IAttachment.OpenCursor, etc.
261  
317 30. TIBXScript: case insensitive regex now used when matching statements instead of
318    converting statement to upper case.
262  
263 < 31. TIBExtract: metadata comments now supported. New published property
321 <    IncludeMetaDataComments (default true). If true then metadata comments included
322 <    in extracted DDL. New Extract Object member eoComments. This may be used with
323 <    ExtractObject method to list all metadata comments.
263 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
264  
265 < 32. TIBExtract: ListObjectNames method added.
265 > 1. Change syntax to Mode Delphi
266  
267 < 33. Updated Database component editor to support additional connection string
268 <    types.
267 > 2. Change all uses of string type to explicit AnsiString in order to ensure
268 >   compatibility between Delphi and FPC.
269  
270 < IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
270 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
271 >   defined for each interface.
272  
273 < NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
333 < AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
334 < RELEASE.
273 > 4. Generics syntax variations for Delphi added
274  
275 < NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
275 > 5. PChar replaced with PByte expect where an actual string is being referenced,
276 >   where PAnsiChar is used instead.
277  
278 < 1. IBExtract: Identity columns - add additional check for null column for generator name.
278 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
279  
280 < 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
341 <   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
342 <   information). However, this is also a very useful mechanism for returning updated computed by
343 <   column values. Values returned as a result of executing an Insert or Update statement
344 <   replace existing values in the current row for each corresponding column.
280 > 7. Testsuite updated for Delphi
281  
282 <   Previously, if a dataset's select query included read only (computed by) fields then
347 <   an automatic row refresh was performed after an insert or update query had been processed,
348 <   irrespective of the setting of the "ForcedUpdates" property. This has changed such
349 <   that an automatic refresh is no longer performed if an insert or update query contains
350 <   a returning clause that updates one or more fields on the current row. A full row
351 <   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
352 <   field values and the select query contains read only fields. Use of Insert/update
353 <   returning should be significantly more efficient than executing a refresh query.
282 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
283  
284 <   This behaviour change is intended to be backwards compatible and there should be no need to change
285 <   existing programs, other than to improve performance by using the new capability.
284 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285 >   large blobs and the FB3 API.
286  
287 < 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
288 <   they are called when the dataset row is being deleted, there is no value in
360 <   updating the current record from the query result. Instead, a new event handler
361 <   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
362 <   an OnDeleteReturning event handler is provided then it is called with the IResults returned
363 <   by the query. The event handler can then interrogate the query results and
364 <   perform whatever action is necessary. For example to confirm, to the user,
365 <   the deletion of a row with the returned values.
287 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
288 >   event block.
289  
290 < 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
368 <   any Computed By or Identity Columns. The IBTables example has been updated to
369 <   illustrate the computation of the employee Full Name on update.
290 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
291  
292 < 5. TIBTable: The GeneratorField property is now published.
292 > 4. Array Handling: fix problem with text arrays with character set none. When the
293 >   DB connection has a default character set (e.g. UTF8), an error is raised by
294 >   Firebird if the space allocated is not enough to allow for transliteration, even
295 >   though it is not required for character set none.
296  
297 < 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
374 <   When InsertSQL is generated, the Identity columns are not included in the list of values to
375 <   be inserted. A RETURNING clause is added to the insert statement to return the value of
376 <   each Identity column after the insert is executed.
297 > 5. IBUtils: List of reserved words brought up-to-date
298  
299 < 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
379 <   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
380 <   Insert..Returning clause.
299 > 6. Add ISQL style performance statistics collection to IStatement
300  
301 < 8. TIBGenerator: small performance improvement by not preparing query each time
302 <   a new value is generated.
301 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 >   CREATE DATABASE statement.
303  
304 < 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
304 > 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
305 >   an array dimension is not mistaken for a named parameter prefix.
306  
307 < 10. Property editors will now sync table name to a System Table when "Include System
308 <    Tables" is selected and the query is for a System Table.
307 > 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
308 >   when Character set is octets. Avoids loss of non printable characters at start of string.
309  
310 < 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
311 <    values are no longer converted to milliseconds from TDateTime and then back again
312 <    to TDateTime (the conversion to milliseconds is the default TDataset approach).
310 > 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
311 >    statistics for the last action. Requires use of procedure IStatement.EnableStatistics
312 >    to enable stats gathering.
313  
314 < 12. Property Editors handling of Stored Procedures.
395 <    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
396 <      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
397 <      query).
398 <    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
314 > 11. API Version information added as constants to IB.pas
315  
316 < 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
401 <    can be used to select a package. If non-empty, the stored procedure name is
402 <    expected to be a stored procedure defined in the specified package and the
403 <    generated SQL will be as required for a stored procedure located in a package.
316 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
317  
318 < 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
406 <    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
407 <    which a stored procedure can be selected. With no package name selected, non-package
408 <    stored procedures are listed.
318 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
319  
320 < 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
411 <    for password on reconnect.
320 > FBINTF Change Log  version                                      (1.0-0) Tue, 06 Dec 2016 10:33:47 +0000
321  
322 < 16. TIBDatabase: use IAttachment for connection default character set id, code page
414 <    and character set name.
322 > 1. Initial Release
323  
416 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
417    DB info lookups"
418
419 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
420
421 19. Add a property Editor for TIBUpdate.RefreshSQL.
422
423 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
424    parameters. This stops an exception being raised when the field cannot be
425    located in the record buffer.
426
427 21. Property Editors now automatically include System Tables when opened and when the query table
428    is a System Table.
429
430 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
431    This avoids errors due to a stale SQRB or SRB being used for the next query.
432
433 23. IBServices: Service attach parameters now include "expected_db". This is used to
434    add the SPB item isc_spb_expected_db. This names a database using
435    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
436    database. examples/services re-written to illustrate use of "expected_db".
437
438 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
439    This avoids truncated backups when the server returns a timeout (busy) response.
440
441 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
442
443 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
444    databasenames. These are respectively expanded to the local system's temp directory
445    (including trailing delimiter) or to a prescribed data directory (including
446    trailing delimiter). Under Unix systems the data directory is a hidden directory
447    in the user's home directory. The hidden directory name is either the string returned
448    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
449    Under Windows, the directory is the same as the Data Directory as decribed
450    above but instead prefixed by the User's application data path. These may be
451    used to improve application portability for Personal Databases.
452
453 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
454    this has not worked for a long time and is not useful either. FieldDefs should be
455    managed using the Fields Editor as with any other dataset. To access the fields
456    editor for a TIBTable component, double click on the component. The fields editor
457    is then displayed.
458
459 28. TIBDatabaseInfo: new properties/function
460     * DateDBCreated (returns date/time database created)
461     * TransactionCount (returns no. of active transactions)
462     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
463     * PagesFree (Firebird 3 or later)
464     * PagesUsed (Firebird 3 or later)
465     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
466     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
467
468 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
469
470 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
471
472 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
473    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
474
475 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
476    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
477    firing during backup and restore.
478
479 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
480    for verbose output using the new property "StatisticsRequested".
481    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
482
483 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
484
485 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
486    palette. This uses the online validation feature added in Firebird 2.5. The
487    services's properties enable inclusion/exclusion of tables and indexes using
488    regular expressions. See.
489    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
490
491 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
492    option on a database.
493
494 37. TIBCustomService: Assign method implemented to allow copying of service login
495    context between service API components. "Detach" method now only detaches
496    service when last reference to the service interface detaches. Tidy up of
497    code for SetActive and Attach methods including password hiding.
498
499 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
500    and used to determine the auth method and protocol used for the connection.
501
502 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
503    a Create Database Statement generated by IBX.
504
505 40. All IBServices now have an additional published property "PortNo". This may
506    be set to a non-standard port number when necessary. If zero then the default
507    port number is used.
508
509 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
510    and not just the mouse.
511
512 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
513
514 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
515    image index and selected image index for each node to be set from a database field.
516
517 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
518    then database schema includes grants to all users. If not present then the
519    only user grants included are those to User PUBLIC.
520
521 45. TIBTreeView: performance improvement. When expanding include both expanded node
522    and child nodes in dataset.
523
524
525 IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
526
527 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
528   changes.
529
530 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
531   Bug could result in truncated multi-byte character set values.
532
533 3. Changes consequential on moving fbintf character set utility functions from
534   IFirebirdAPI to IAttachment.
535
536 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
537
538 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
539   results in autocomplete ignoring prefix text.
540
541 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
542   entering a new name into the text box.
543
544 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
545   Firebird rather than recomputing it.
546
547 8. Property Editor positioning tidy up: All IBX Property editors should now be
548   screen centre. Previously some were "poDesigned" which may be inappropriate
549   for multi monitor desktops.
550
551 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
552
553 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
554    a transaction and always reset the object.
555
556 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
557
558 13. TIBXScript: Allow for override of database filename in Create Database statements.
559
560 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
561    to a gbak format archive.
562
563 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
564
565 16. IBLocaldb: Drop database if error creating an empty database.
566
567 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
568    unless selected node not in current dataset.
569
570 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
571    to TIBCustomService, and IBlocalDB code tidy up.
572
573 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
574    behaviour due to uninitialised variable.
575
576 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
577    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
578
579 21. IBSQL: When Database changed ensure that all resources are freed.
580
581 22. IBCustomDataset: When database changed ensure that queries an unprepared.
582
583 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
584    * Line Wrap on SQL Token boundaries (on user command)
585    * auto-complete table names in drop down list of table names
586    * Double click on tablename or field name adds to SQL text
587
588 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
589
590 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
591    TVariantArray. Seems to avoid memory corruption in Windows (probably a
592    workaround for a problem in fpc 3.0.4 win64).
593
594 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
595
596 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.

599
600 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
601   include remote system name.
602
603 2. TIBExtract: No longer include comment header and COMMIT statement for empty
604   tables when data included in output.
605
606 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
607   and timing information to be written to stdout. This may be used to locate
608   performance bottlenecks.
609
610 4. SQLParser: only call "OnChanging" event handler when value is different.
611
612 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
613
614 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
615   that BindFields is called when the query is next activated. Avoids FieldName
616   not found error.
617
618 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
619   purpose and allows the programmer to define any action they want for Update, Insert
620   or Delete. This may be complex SQL (similar to a Trigger), application specific
621   filtering of updates, or use of statements such as Grant or Revoke instead of
622   normal DML. See User Manual for more information.
623
624 IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
625
626 1. TIBEvents: Fix uninitialised variable that could result in lost events.
627
628 2. TIBExtract: Added support for FB3 "USAGE" privilege.
629
630 3. TIBExtract: data formatted as Charset set "octets" is now output using
631   hexadecimal notation.
632
633 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
634   using a simple XML format.
635
636 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
637   grants to these objects.
638
639 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
640   dependency problems restoring complex databases.
641
642 7. TIBXScript: This component has been restructured to allow for the processing of
643   embedded XML in INSERT statements and to support interactive sources in addition
644   to non-interactive data sources such as files.
645
646 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
647
648 9. TIBXScript: ISQL compatiable Set statements are now supported:
649   SET SQL DIALECT
650   SET TERM
651   SET AUTODDL
652   SET BAIL
653   SET ECHO
654   SET COUNT
655   SET STATS
656   SET NAMES <character set>
657
658 10. IBVersion unit added to hold current IBX Version Number information.
659
660 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
661    and domain definitions.
662
663 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
664    fully supported.
665
666 13. TIBExtract: when a database dump includes data, the generator values are now also set.
667
668 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
669
670 IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
671
672 See also doc/IBX4LazarusGuide.pdf for important information on
673 upgrading to IBX2.
674
675 1. Size property of TIBStringField is now the width in characters of the field
676   and not the byte length. This applies only to multi-byte character sets such
677   as UTF8. The original approach aligned with TStringField. However, the TStringField
678   code is not recognised as a bug and hence this change to align the behaviour.
679   The TStringField change is expected in fpc 3.2.0.
680
681 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
682   true (default) then Size property value saved in the lfm is ignored. Size is
683   always set from the dynamic information read from the database. It is unclear
684   why anyone would want to override this and set Size to false.
685
686 3. ibxscript: should now handle correctly a Case..End statement within a procedure
687   block.
688
689 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
690   exist when an attempt is made to connect to it (run time only) then an attempt
691   is made to create the database.
692
693 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
694   has been successfully created as a result of a call to CreateDatabase or when
695   creating a database after it was found not to exist.
696
697 6.  DBControlGrid: a race condition could result in the wrong row image being
698    written to the cache. This has been avoided by a trip round the message
699    loop before rendering the row image.
700
701 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
702    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
703    known to risk corrupt rendering of row images when the control is first
704    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
705    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
706
707 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
708    a TDateEdit control located on an editor panel.
709
710 9.  TIBExtract: brought up-to-date plus many bug fixes.
711
712 10. DBControlGrid: Removed memory leak when updating rows.
713
714 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
715
716 IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
717
718 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
719   when target codepage is CP_NONE. This is a workaround for
720   http://bugs.freepascal.org/view.php?id=30622.
721
722 2. DBLog option removed from TIBStatisticalService - not supported by server
723   since Firebird 1.5.
724
725 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
726   similar.
727
728 4. IBCodePage: updated mapping between codepages and character id.
729
730 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
731   Firebird. Character sets with a char width of two are not UTF16.
732
733 6. Strings received from the database are now always transliterated into UTF8
734   regardless of the database character set or connection character set. This
735   is for compatibility with the LCL.
736
737 IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
738
739 1. IBBlob: Defer reading of blob until read method called. This avoids having to
740   read in an entire blob just to get the size of the blob. General performance
741   improvement when opening datasets containing blobs.
742
743 2. Clearing a  Blob now sets the corresponding field's modified flag.
744
745 3. IBLookupCombo: When not performing auto-complete, original query sort order
746   is now used.
747
748 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
749   determined.
750
751 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
752
753 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
754   lazarus 1.6.0
755
756 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
757   compilation error.
758
759 IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
760
761 1. No character set specified for connection: when a text blob is retrieved, the
762  character set is determined by looking up the native character set using then
763  Firebird API. Otherwise a text mode blob is assumed to have the same character
764  set as the connection.
765
766 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
767   for Login Dialog returing a change to the database path.
768
769 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
770   to be changed from that given in the TIBDatabase/TIBServer component and for the
771   entered value to be saved on a project specific basis (design time only).
772
773 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
774   column fieldname. If they are the same then it is acts as a look up for the KeyValue
775   Otherwise, it sets the column text to the selected ListField Value.
776
777 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
778   column width.
779
780 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
781   and a case insensitive search is requested.
782
783 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
784   or column ListSource.
785
786 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
787   unprepare) when closing and the text has not changed.
788
789 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
790   Less likely to cause a cursor re-use error on Windows.
791
792 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
793   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
794
795 11. TIBTreeView: Guard against nil destination on record changed
796
797 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
798    string type with the code page set to reflect the returned field encoding after
799    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
800    earlier versions.
801
802 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
803    will now result in transliteration to the code page specified for the Firebird driver
804    if the assigned string has a different code page. FPC 3.0.0 onwards only.
805
806 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
807    is ignored and the lc_ctype value, when the database is opened, is set to align with
808    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
809    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
810    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
811    the GETACP is used to determine the Windows code page.
812
813 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
814    name used as the lc_ctype when the database was opened. Only valid while the
815    Database is connected.
816
817 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
818    id that corresponds to the DefaultCharSetName.
819
820 IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
821
822 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
823   path is given and database attach fails due to access permission issues on the
824   temp directory or security database, then the attach is retried with "localhost:"
825   prefixing the databasename. This should avoid problems when the database has to
826   be accessed by a local (e.g. classic) server and libfbembed is used.
827
828 2. Windows: revised search order for Firebird DLL:
829     i.   The Firebird Embedded Server in the application Directory.
830     ii.  If the FIREBIRD environment variable is set then the directory this
831          points to is searched for the FB Client DLL and then then underlying
832          "bin" directory.
833     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
834          is used to locate the Firebird installation directory and the underlying
835          "bin" directory is searched for the FB Client DLL.
836     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
837          are searched for the FB Client DLL.
838     v.   The PATH Environment variable is used to search for the FB Client DLL.
839     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
840
841 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
842   See doc/readme.scriptengine and example applications.
843
844 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
845   simplify the use of the embedded firebird server on both Linux and Windows platforms.
846   See dpc/readme.localdatabase and example applications.
847
848 5. IBDynamicGrid: Reordering on column header click should now also work for
849   dynamic columns.
850
851 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
852   between incrementing/decrementing the lock count and signalling the event.
853
854 IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
855
856 1.3.2 was never formally released and only made available as beta copies.
857
858 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
859
860 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
861
862 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
863
864 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
865   i.e. when it is a calculated field
866
867 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
868   This problem was due to a race condition between recalculating row heights and
869   determining which row was selected by the mouse click. The row height calculation
870   is now deferred by an extra trip round the message loop allowing the row to
871   be always calculated on the current grid layout rather than risking it being
872   calculated on the grid layout after the expanded row has been shrunk.
873
874 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
875   Windows.
876
877 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
878   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
879   to be determined at runtime. See doc/readme.charactersets.html.
880
881 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
882   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
883
884 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
885   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
886   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
887
888   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
889   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
890   implies no truncation.
891
892 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
893
894 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
895   (avoids "Not in Edit Mode" error).
896
897 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
898
899 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
900    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
901
902 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
903
904 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
905
906 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
907
908 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
909
910 IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
911
912 1.   OnCloseUp Event Handler added to TDBLookupProperties
913
914 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
915     problem with row size when exception is called.
916
917 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
918
919 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
920     in a TCustomComboBox and ignores return key if in a TCustomMemo
921
922 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
923     keyed in i.e. when autocomplete not performed
924
925 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
926     console mode applications with all LCL required functions (builtin dialogs and
927     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
928     not included in your project, IBX should compile and link with a console mode program.
929     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
930     console mode application or the IDE will automatically assume that your
931     application is GUI based. Instead, you should include the ibexpressconsolemode package.
932
933     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
934     to use the built in dialogs and cursor management. IBDialogs is
935     included by default if "ibexpress" is in your project source's "uses" clause.
936     This should be the case for all projects created through the IDE. This is why
937     you do not want to add the ibexpress package to console mode applications. The
938     ibexpressconsolemode package has been created to allow console mode programs
939     to avoid adding LCL dependencies when using IBX, while still having the
940     unit search paths set up correctly.
941
942     Existing users should check to ensure that the "ibexpress" unit is included in
943     each project's source file (*.lpr).
944
945     You may find that in order for the IDE to recognise that ibexpressconsolemode
946     exists, you have to first open the package in the IDE and then close it. This
947     adds it to the most recently accessed packages list. To make it permanently
948     available, add the package name to lazarus' staticpackages.inc file.
949
950         Thanks to Julio Jiménez for suggesting support of console mode.
951
952 7.   SQL Parser can now accept quoted strings that include new lines
953
954 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
955     of text on start of edit. This is particularly useful when tabbing to a
956     column and then inserting text.
957
958 9.   New Examples provided for IB Services and ISQLMonitor.
959
960 10. Fix error when writing to blob streams that recorded only the last buffer
961    write in the blob stream. In most cases, this did not cause a problem as the
962    IB Blob Stream is written in a single write. However, with the TDBImage, write
963    of a graphic type prefix was lost which caused a problem when the image could
964        not be automatically recognised.
965
966 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
967    already open" errors due to random numbers used for the cursor name being identical.
968
969 12. IBTable: corrected error that could result in an "Index out of bounds" error
970    when opening the table and the Primary Key is the last or only column in the
971    table. Thanks to Rick Hoover for the fix.
972
973 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
974    of "UTF-8", and update list of available database character sets. Existing
975    users should check the current lc_ctype setting in their applications.
976
977 IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
978
979 1.  Firebird Services: avoid List Index error when opening a service with an
980    empty Params property.
981
982 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
983    Link now set up in Loaded method - avoids occasional failure to apply
984    SQL markup on initial open.
985
986 3.  "Employees" example performance improvements when scrolling.
987
988 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
989    TFrame. Force recaching of selected frame to avoid GTK race (results in a
990    random image cached).
991
992 5.  DBControlGrid: Should now react to changes in panel height at run time.
993
994 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
995    even when further rows exist.
996
997 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
998    always be derived from panel height and setting this property can cause confusion.
999    Note for existing projects: to avoid a missing property error at run time,
1000    each form using the DBControlGrid must be opened, updated and saved in the IDE
1001    in order to remove the property value from the lfm.
1002
1003
1004 IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1005
1006 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1007    call Prepare before setting parameter values.
1008
1009 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
1010
1011 3.  Code tidyup and more robust handling of dsql information result vector.
1012
1013 4.  Support for centralised handling of transaction status changes. TIBTransaction
1014    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1015    and "AfterExecQuery". The first three are called after the same event is called
1016    for an IBCustomDataSet descendent using the Transaction. The fourth is called
1017    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1018    enable monitoring of transaction status changes for a given transaction to be
1019    handled in a single place. For example, when a change to the dataset occurs
1020    an indicator can be set that shows the user that in order to save changes,
1021    the transaction should be committed.  Rather than doing this per dataset, this
1022    can now be done per transaction.
1023
1024 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
1025    the dataset is scrolled. However, any changes to the current row are, by default,
1026    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1027    have a new property "DataSetCloseAction" that adds automatic posting of changes
1028    on dataset close. If this property is set to dcDiscardChanges (default) then the
1029    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1030    then IBX will attempt to post any unsaved changes before the dataset is closed
1031    (and after the BeforeClose event handler is called). The exception is when the
1032    dataset is being closed as a result of a transaction rollback. In this case,
1033    no action is taken and any unsaved  changes are discarded. This avoids both
1034    unnecessary overhead and the risk that a validation error may occur in the Post
1035    raising an exception and thereby preventing a rollback.
1036
1037 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
1038    In earlier versions, the Display Width was set to the maximum byte width rather than the character
1039    width. Display Widths are now corrected by dividing by the max byte width per character.
1040    For UTF8 character sets, the byte width is four and hence the Display Width will be
1041    the byte width divided by 4. The byte width of each character set is determined
1042    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1043    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1044
1045 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1046
1047 8.  IBLookupComboEditBox: List should now always be restored to full list when the
1048    control loses focus. Default Key press default interval reduced to 200ms.
1049
1050 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
1051    when dataset rows are less than visible rows.
1052
1053 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1054    does not exist or DataSet is empty. More responsive on dataset open. New event
1055    OnRestorePosition. Column sort disabled if no header row.
1056
1057 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1058    while dataset state is dsInsert. Avoids posting errors.
1059
1060 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1061    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1062
1063 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1064
1065 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1066    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1067    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1068    always "posts" the current record regardless or whether or not it may be more appropriate
1069    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1070    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1071    as the first action of the "Post" method and allows the handler to convert the Post
1072    into a Cancel if that is the appropriate action on moving to a different row. This is
1073    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1074    raised here, but it may still be more appropriate to validate a post and signal
1075    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1076
1077 15. On Unix derived systems, the Firebird library name can now be given as a colon
1078    separated list. Each library name on the list is tried in turn, in left to right
1079    order with the first found being used as the firebird library. By default, on Linux,
1080    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1081    overidden by the FBLIB environment variable or the OnGetLibraryName function.
1082
1083    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1084    then it will still attempt to access the database via the Firebird Server and will
1085    require a username and password. If only the pathname is given, then the username
1086    and password should be omitted and the unix file permissions are used to grant
1087    access.
1088
1089 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1090
1091 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1092    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1093    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1094    corresponds to a row of the linked DataSource. Any data aware control on the
1095    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1096
1097 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1098   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1099   takes place during database access. This may be useful when there are performance issues with
1100   the change of cursor. Setting the property to false suppresses the change of cursor.
1101
1102 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1103   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1104   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1105   making all changes permanent immediately rather than when the transaction is explicitly
1106   committed.
1107
1108 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1109   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

1113 Development version only.
1114
1115 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1116
1117 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1118   This is typically used during an "OnBeforeOpen" event handler to manipulate the
1119   "Where" and "Having" clauses to implement user specified filters of arbitrary
1120   complexity.
1121
1122 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1123   three new data aware controls dependent on IBX and which make use of the SQL Parser.
1124   These are:
1125
1126   - TIBLookupComboEditBox
1127   - TIBDynamicGrid
1128   - TIBTreeview
1129
1130   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1131   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1132   to revise the available list and restrict it to items that are prefixed by the
1133   typed text (either case sensitive or case insensitive). Autoinsert allows a
1134   newly typed entry to be added to the list dataset and included in the available
1135   list items.
1136
1137   TIBDynamicGrid is a TDBGrid descendent that provides for:
1138   - automatic resizing of selected columns to fill the available row length
1139   - automatic positioning and sizing of a "totals" control, typically at the
1140     column footer, on a per column basis.
1141   - DataSet resorting on header row click, sorting the dataset by the selected column.
1142     A second click on the same header cell reversed the sort order.
1143   - Support for a "Panel Editor". That is on clicking the indicator column, the row
1144     is automatically expanded and a panel superimposed on it. The panel can have any
1145     number of child controls, typically data aware controls with the same datasource
1146     as the grid allowing for editing of additional fields and more complex editors.
1147   - Reselection of the same row following resorting.
1148   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1149     Its properties are specified on a per column basis and allows for one or more
1150     columns to have their values selected from a list provided by a dataset.
1151     Autocomplete and autoinsert are also available. The existing picklist editor
1152     is unaffected by the extension.
1153
1154   TIBTreeView is a data aware TCustomTreeView.
1155
1156 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1157   zero scale will no longer return an error. An Int64 will be returned instead.
1158
1159 4. TIBTransaction now has events for Before and After Transaction End and a new function
1160   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1161
1162 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1163   repeated multiple times.
1164
1165 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1166   check used to get in the way of using Stored Procedures, and "Update or Insert"
1167   statements.
1168
1169 7. Insert, Modify and Delete property Editors now support Query Generation from
1170   Stored Procedures.
1171
1172 8. Three new examples illustrate the use of the new IB Controls
1173
1174
1175 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1176
1177 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1178   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1179   Gabor Boros for reporting this problem and for testing the improvements).
1180
1181 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1182   See readme.field+param.names in the doc folder.
1183
1184 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1185   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1186
1187 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1188
1189 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1190   actions.
1191
1192 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1193   thanks to Yuriy Kopnin for pointing this out).
1194
1195 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1196
1197 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1198   for both fields and parameter setting.
1199
1200 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1201   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1202
1203 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1204    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1205
1206 11. TIBTable now has a property editor for "MasterFields"
1207
1208 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1209    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1210
1211 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1212    of settings is unrecognised. Selecting this radio button has no effect on the settings.
1213

1215 IBX Change Log  version                 (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1216
1217 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1218
1219 IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1220
1221 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1222   it is null. This allows for alternative user defined setting of the generator
1223
1224   Many thanks to Julio Jiménez for this fix
1225
1226 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1227   and suggests that the user may have forgotten to install it.
1228
1229 IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1230
1231 1. Conditional compilation used to limit registration of TIntegerField to
1232   Lazarus versions less than 1.1
1233
1234 2. When a database connection is created, character set is now by default set
1235   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1236   1250 to 1254.
1237
1238
1239 IBX Change Log  version     (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1240
1241 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1242
1243
1244 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1245
1246 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1247   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1248
1249 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1250   package is changed to do this (which it should do).
1251
1252 IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
1253
1254 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1255
1256 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1257
1258 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1259
1260 4. Property editors should now correctly resize.
1261
1262 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1263   (restored original functionality)
1264
1265 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1266   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
