1 < IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
1 > FBINTF Change Log  version          (1.1-6 Build 12214) Fri, 17 Jul 2020 23:10:11 +0100
3 < 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
4 <    not SQL Identifiers are now supported.
3 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
4 >   with a Firebrid 3 client library.
6 < 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
7 <    passed to the Firebird engine for execution.
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.
12 < 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
10 <    is made to scroll back.
12 > 3.  IUtil.FormatStatus now used to format error messages when using new API
14 < 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
14 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
16 < 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
17 <   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
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.
23 < 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
24 <   validated. If no match is found in the list of field names and the database has
25 <   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
20 <   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
23 > 6.  New IFirebirdAPI Calls:
24 >      function GetClientMajor: integer;
25 >      function GetClientMinor: integer;
22 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
23   with fpc 3.2.
28 < IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
28 > FBINTF Change Log  version          (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
30 + 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
31 +   case sensitive
33 < 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
29 <   and is used to override the default settings in the client side "firebird.conf" This
30 <   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
31 <   Each line of the string list should be a setting in the same format as "firebird.conf".
32 <   For example "WireCompression = true" in order to request wire compression on the client side.
33 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
35 <   Note: explicit settings in the client side "firebird.conf" appear to take precedence
36 <   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
37 <   also require a compatible setting in the server side "firebird.conf". For example
38 <   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
39 <   compression to be used.
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)
43 <   Whether or not WireCompression or WireCrypt are in use can be checked using the information
41 <   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
42 <   ibx/examples/dbinfo for examples of how to display this information.
43 > 4. FBMessages: removal of unused messages
45 < 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
45 <   is a "convenience" property. If set the "WireCompression=true" is added to the
46 <   ConfigOverrides. If unchecked then this setting is removed.
45 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
47 < 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
49 <   not "INT64".
47 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
49 < 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
52 <   These are:
53 <    property TimestampFormat: string;
54 <    property DateFormat: string;
55 <    property TimeFormat: string;
49 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
51 <   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
52 <   DATETIME and TIME. The format strings use the standard FPC date/time format
59 <   characters (see
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.
54 <   If any of the above properties are set to an empty string, then the locale default
55 <   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
56 <   locale default is extended by appending '.zzz' to include milliseconds.
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.
58 <   TIBCSVDataOut by default sets these properties to the empty string, while the other
59 <   two use: ' hh:nn:ss.zzz', '' and 'hh:nn:ss.zzz' respectively.
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.
62 < 5. New published property for TIBCSVDataOut:
69 <     property QuoteStrings: boolean (default true)
62 > 4. IColumnMetaData: new method.
64 <   If false then strings are unquoted, otherwise, the QuoteChar property value is
65 <   used to delimit each and every string in the output.
64 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
65 >                        dfDateTime,   {SQL DATETIME}
66 >                        dfTime);
68 < 6. New published properties for TIBCSVDataOut:
75 <    property FieldSeparator: string;
76 <    property HeaderSeparator: string;
68 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
70 <   Respectively, these provide the separator character(s) used to separate fields
71 <   in data and header rows. Both default to ','.
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.
73 < 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
74 <    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
83 <    property OnFormatTextString;
73 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
74 >     CaseSensitiveParams: boolean = false
76 <   This event handler can be used to process text strings before they are included
77 <   in the output e.g. to replace unprintable characters with alternative strings.
78 <   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
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.
80 < 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
81 <   Uses "FindParam" if in order to find out if a parameter with a given name exists
82 <   and without raising and exception if it does not.
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.
93 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
94   consistency with SQL queries.
96 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
97    When true, SQL statement parameter names are parsed case sensitive. Note for
98    TIBDataSet only applies to Select query.
87 < 11. IBEvents: removing a TIBEvent component from a form should no longer result in
101 <    an IDE exception.
87 > FBINTF Change Log  version                  (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
89 < 12. LocalDBSupport: initial database creation should now work correctly
104 <    when the schema source is an sql file.
89 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
91 < 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
92 <    when defined, this handler will be called by the internal TIBXScript during
108 <    initial database creation when the schema source is an sql file and may be used
109 <    to provide a visual indication of progress in console mode.
91 > 2. Restrict IsMultiThread check to Unix only for compatibility with
92 >
94 < 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
95 <    to true while a new local database is being created and its schema populated.
96 <    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
114 <    when the database is disconnected/connected during the create DB procedure.
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.
98 < 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
99 <    are now always ignored and replaced by the user name and password provided as
118 <    the login parameters for the TIBDatabase referenced from the TIBXScript. The
119 <    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
120 <    completely ignored if this property is true.
98 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
99 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
101 < 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
123 <    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
124 <    ImageIndex and SelectImageIndex values on AddNode.
101 > 5. New function added to IB.pas
103 < 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
127 <    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
128 <    the same database connection.
103 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
105 < 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
106 <    if provided, this should be an conditional SQL expression suitable for
107 <    including in an SQL Select statement "where" clause. If non-empty and the
108 <    "Filtered" property is true then the SQL expression provided as the value of
134 <    the "Filter" property is "ANDed" with any existing condition statement
135 <    in the SQL statement's "Where" clause.
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.
110 <    If the "Filter" property is set at run time, the "Filtered" property is true
138 <    and the dataset is already open, then the dataset is closed and re-opened automatically.
110 > FBINTF Change Log  version               (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
112 <    The "Filter" condition may include IBX style parameters. In which case, their
113 <    value must be set by the dataset's "OnBeforeOpen" event handler.
112 > 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
113 >   program compiled with -CR command line switch.
115 <    This is a public property for TIBDataSet and TIBQuery query and intended for
116 <    use at run time.
115 > 2. IServiceManager additions (informational):
116 >    function getProtocol: TProtocol;
117 >    function getPortNo: AnsiString;
119 <    Note: The property is a published property of TIBTable. The TIBTable functionality
120 <    is unaffected by this change.
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;
124 < IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
124 > 4. IAttachment addition (informational)
125 >    function GetSecurityDatabase: AnsiString;
127 < 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.
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.
131 < 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.
131 > 6. DARWIN: bug fix. Many thanks to Luigi Naimi for correcting
132 >   the problem.
134 < 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
135 <   internal SQL tokeniser routines.
134 > 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
135 >   replaces deprecated "comp" type.
137 < 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
162 <   as a select statement, with or without CTEs.
137 > 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
139 < 5. IBSQLParser: parser now recognises the "ROWS" clause.
139 > 11. URL Connection Strings: inet4 and inet6 now recognised.
141 < 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
167 <   internal SQL tokeniser routines.
141 > 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
143 < 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
170 <    being raised for valid set statements processed by a data formatter.
143 > 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
172 8. New published property for TIBDatabase and TIBXServicesConnection. This is
173   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
174   the path of the Firebird Library used by the database/services connection.
146 < 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
177 <   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
178 <   services connection.
146 > FBINTF Change Log  version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
148 < 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
181 <   or param name is not a valid SQL identifier.
148 > 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
150 < 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
151 <    view of whether the text box should be editable when no DataSource is specified.
152 <    TIBLookupComboEditBox has been updated to workaround this problem. As long as
186 <    ReadOnly is false, the text box is editable when no DataSource is specified.
150 > 2. IAttachment: add two new methods
151 >     function HasDefaultCharSet: boolean;
152 >     function GetDefaultCharSetID: integer;
154 < 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
155 <    the FBLIB environment variable. If you do not want to permit this then you
156 <    must modify the Register procedure in the design/IBDBReg.pas unit to remove
157 <    this setting.
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.
159 < IBX Change Log  version                 (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
159 > 3. Avoid exception when a text blob is a stored procedure parameter.
161 < 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
196 <   Utf8EscapeControlChars
161 > 4. Update test suite to include a test for a stored proc returning a text blob.
163 < IBX Change Log  version                (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
163 > 5. IAttachment: add
164 >      function GetRemoteProtocol: AnsiString;
165 >      function GetODSMajorVersion: integer;
166 >      function GetODSMinorVersion: integer;
167 >      function GetAuthenticationMethod: AnsiString;
169 < IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
170 < all previous copies of the IBX source code tree before installing this release.
169 >   These results are cached when the connection is opened and hence do not
170 >   require a database lookup.
172 < The IBX packages used by most users have not changed, with one exception. The
173 < IBServices unit has been moved to the package iblegacyServices.lpk. To continue
205 < to use the IBServices unit in your applications, please add the iblegacyServices
206 < to the list of dependencies. To do this, open the Project Inspector and select
207 < Add->New Requirement and select "ibLegacyServices" from the list of available
208 < packages.
172 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
173 >   connect string used to create/connect to the database.
175 < 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
176 <   the IBServices unit providing what is intended to be a clearer and easier to
177 <   use set of IB Services components. See Chapter 10 of the IBX User Guide for
178 <   more information and the guide to "Firebird Service Management Using IBX".
179 <   As indicated above, the legacy services components are still available and
215 <   provided in a separate package. There is no need to update working applications
216 <   using the older versions except for an additional package dependency.
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.
181 < 2. The IBX packages and source code tree have been re-organised in an attempt to
219 <   finally get rid of the "duplicate ppu" warnings. This re-organisation should
220 <   not affect existing users. Section 2.3 of the IBX User Guide describes the
221 <   new set of IBX packages.
181 > 8. Update Test 1 to test 5, 6 and 7 above.
183 < 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
224 <   updated to use the new Services API components.
183 > 9. IBUtils code tidy up.
185 < 4. The iblocal package has been updated to use the new Services API components.
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.
190 < 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
229 <   TIBXSecurityService. It had been wrongly classified in the previous version
230 <   as a per database configuration item. It is global to a server and hence
231 <   correctly positioned as part of the Security Package. In the DBAdmin example,
232 <   the setting has moved to the mappings page.
190 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
192 < 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
193 <   are ignored.
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.
197 < 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
198 <   closed before the database is dropped. Before and After Disconnect event handlers
239 <   are also fired.
197 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
198 >    test suite updated.
200 < 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
201 <   is started and not just the first time.
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.
203 < 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
204 <   depenendency with comp type.
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.
207 < 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
207 > FBINTF Change Log  version                             (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
209 < 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
210 <    then this is recognised and not ignored.
209 > 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
210 >   Scale is no longer ignored.
212 < 12. TIBDataSet, TIBQuery, TIBTable: additions:
213 <    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
214 <    function GetPerfStatistics(var stats: TPerfCounters): boolean;
215 <    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
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.
217 <    GetRowsAffected returns the affected row counts from the last insert/update/delete
218 <    if EnableStatistics = true then GetPerfStatistics returns the current stats
259 <    counters for the select query. Note: stats accumulate after each fetch from
260 <    the database. To get total query cost after open, call the "Last" method
261 <    and then GetPerfStatistics.
217 > 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
218 >   UTF8 and not UNICODE_FSS.
220 <    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
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.
225 < 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
226 <    in parenthesises.
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.
230 < 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
231 <    SQL identifiers are always delimited by double quotes. If false, then they are
270 <    only delimited if the identifier is a reserved word, contains lower case or special
271 <    characters. Set this property to true to retain previous behaviour.
230 > 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
231 >   set supported by Firebird with the API.
233 < 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
234 <    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
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.
236 < 16. TIBDataSet, TIBQuery, TIBTable: addition:
277 <       property MasterDetailDelay: integer {defaults to zero}
236 > 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
238 <    When non-zero and the dataset is a detail table referencing a master table
239 <    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
240 <    then a synchronisation delay is added (in milliseconds) between the master
241 <    row changing and the detail dataset being re-opened. If the master dataset
283 <    is scrolled before the delay expires then the delay is reset. This can be used
284 <    to avoid performance overheads when scrolling through a large master dataset.
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.
243 <    Note: uses fptimer and hence requires a thread manager. Under Linux the
287 <    chreads unit must be included in your project. TTimer is not used in order
288 <    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
243 > 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
245 < 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
291 <    with Extract Option eoDatabase.
245 > 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
247 < 18. TIBLookupComboEditBox: Workaround added for
294 <    When a deLayoutChanged event is reported on the ListSource dataset, the
295 <    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
296 <    relationship with the control's datasource (master).
247 > 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
249 < 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
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.
254 < 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
301 <    stubs. Pedantic fix really, as procedures output in dependency order anyway.
254 > 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
256 < 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
257 <    DDL (Firebird 3 and later only).
256 > 15. FBAttachment: Avoid string reference count error when processing an Ansistring
257 >    parameter in an array of const passed to IAttachment.OpenCursor, etc.
259 < 22. TIBLookupComboBox Autocomplete Fixes:
260 <    i. Only appended text is now selected after autocomplete.
308 <    ii. Uppercase keys no longer ignored for autocomplete.
309 <    iii. Retain Prefix case is now honoured correctly.
310 <    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
311 <        before autocomplete performed. i.e. behaviour now the same as when
312 <        no DataSource assigned.
259 > 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
260 >    of const passed to IAttachment.OpenCursor, etc.
314 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
315    between SQL statements.
263 < 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
318 <    ObjectNames are converted to upper case before matching against metadata object
319 <    names, unless the objectname is delimited by double quotes, in which case, the
320 <    double quotes are removed and the remaining string is used (unmodified) to match
321 <    against the metadata object name.
263 > FBINTF Change Log  version             (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
265 <    If true then the ObjectName is used as is without modification and matched
324 <    against the metadata object name. No attempt is made to remove double quotes.
265 > 1. Change syntax to Mode Delphi
267 < 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
268 <    with eoTrigger, these extract types can be used to select only Database Triggers,
328 <    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
267 > 2. Change all uses of string type to explicit AnsiString in order to ensure
268 >   compatibility between Delphi and FPC.
270 < 26. TIBXScript: If an exception occurs during the processing of a statement, the
271 <    statement separate character is now reset to the default (';').
270 > 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
271 >   defined for each interface.
273 < 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
273 > 4. Generics syntax variations for Delphi added
275 < 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
276 <    a commit or reconnect statement and instead activated only when next SQL statement
337 <    is executed.
275 > 5. PChar replaced with PByte expect where an actual string is being referenced,
276 >   where PAnsiChar is used instead.
278 < 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
278 > 6. Review of type definitions in IBExternals to ensure Delphi compatibility
280 < 30. TIBXScript: case insensitive regex now used when matching statements instead of
342 <    converting statement to upper case.
280 > 7. Testsuite updated for Delphi
282 < 31. TIBExtract: metadata comments now supported. New published property
345 <    IncludeMetaDataComments (default true). If true then metadata comments included
346 <    in extracted DDL. New Extract Object member eoComments. This may be used with
347 <    ExtractObject method to list all metadata comments.
282 > FBINTF Change Log  version            (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
284 < 32. TIBExtract: ListObjectNames method added.
284 > 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
285 >   large blobs and the FB3 API.
287 < 33. Updated Database component editor to support additional connection string
288 <    types.
287 > 2. Update Event Handling algorithm to avoid looping due to recreation of the
288 >   event block.
290 < IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
290 > 3. Avoid invalid XSQLDA error when the only parameter is updated to null
294 < RELEASE.
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.
297 > 5. IBUtils: List of reserved words brought up-to-date
299 < 1. IBExtract: Identity columns - add additional check for null column for generator name.
299 > 6. Add ISQL style performance statistics collection to IStatement
301 < 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
302 <   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
366 <   information). However, this is also a very useful mechanism for returning updated computed by
367 <   column values. Values returned as a result of executing an Insert or Update statement
368 <   replace existing values in the current row for each corresponding column.
301 > 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
302 >   CREATE DATABASE statement.
304 <   Previously, if a dataset's select query included read only (computed by) fields then
305 <   an automatic row refresh was performed after an insert or update query had been processed,
372 <   irrespective of the setting of the "ForcedUpdates" property. This has changed such
373 <   that an automatic refresh is no longer performed if an insert or update query contains
374 <   a returning clause that updates one or more fields on the current row. A full row
375 <   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
376 <   field values and the select query contains read only fields. Use of Insert/update
377 <   returning should be significantly more efficient than executing a refresh query.
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.
307 <   This behaviour change is intended to be backwards compatible and there should be no need to change
308 <   existing programs, other than to improve performance by using the new capability.
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.
310 < 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
311 <   they are called when the dataset row is being deleted, there is no value in
312 <   updating the current record from the query result. Instead, a new event handler
385 <   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
386 <   an OnDeleteReturning event handler is provided then it is called with the IResults returned
387 <   by the query. The event handler can then interrogate the query results and
388 <   perform whatever action is necessary. For example to confirm, to the user,
389 <   the deletion of a row with the returned values.
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.
314 < 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
392 <   any Computed By or Identity Columns. The IBTables example has been updated to
393 <   illustrate the computation of the employee Full Name on update.
314 > 11. API Version information added as constants to IB.pas
316 < 5. TIBTable: The GeneratorField property is now published.
316 > 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
318 < 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
398 <   When InsertSQL is generated, the Identity columns are not included in the list of values to
399 <   be inserted. A RETURNING clause is added to the insert statement to return the value of
400 <   each Identity column after the insert is executed.
318 > 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
320 < 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
403 <   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
404 <   Insert..Returning clause.
320 > FBINTF Change Log  version                                      (1.0-0) Tue, 06 Dec 2016 10:33:47 +0000
322 < 8. TIBGenerator: small performance improvement by not preparing query each time
407 <   a new value is generated.
322 > 1. Initial Release
409 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
411 10. Property editors will now sync table name to a System Table when "Include System
412    Tables" is selected and the query is for a System Table.
414 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
415    values are no longer converted to milliseconds from TDateTime and then back again
416    to TDateTime (the conversion to milliseconds is the default TDataset approach).
418 12. Property Editors handling of Stored Procedures.
419    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
420      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
421      query).
422    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
424 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
425    can be used to select a package. If non-empty, the stored procedure name is
426    expected to be a stored procedure defined in the specified package and the
427    generated SQL will be as required for a stored procedure located in a package.
429 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
430    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
431    which a stored procedure can be selected. With no package name selected, non-package
432    stored procedures are listed.
434 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
435    for password on reconnect.
437 16. TIBDatabase: use IAttachment for connection default character set id, code page
438    and character set name.
440 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
441    DB info lookups"
443 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
445 19. Add a property Editor for TIBUpdate.RefreshSQL.
447 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
448    parameters. This stops an exception being raised when the field cannot be
449    located in the record buffer.
451 21. Property Editors now automatically include System Tables when opened and when the query table
452    is a System Table.
454 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
455    This avoids errors due to a stale SQRB or SRB being used for the next query.
457 23. IBServices: Service attach parameters now include "expected_db". This is used to
458    add the SPB item isc_spb_expected_db. This names a database using
459    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
460    database. examples/services re-written to illustrate use of "expected_db".
462 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
463    This avoids truncated backups when the server returns a timeout (busy) response.
465 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
467 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
468    databasenames. These are respectively expanded to the local system's temp directory
469    (including trailing delimiter) or to a prescribed data directory (including
470    trailing delimiter). Under Unix systems the data directory is a hidden directory
471    in the user's home directory. The hidden directory name is either the string returned
472    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
473    Under Windows, the directory is the same as the Data Directory as decribed
474    above but instead prefixed by the User's application data path. These may be
475    used to improve application portability for Personal Databases.
477 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
478    this has not worked for a long time and is not useful either. FieldDefs should be
479    managed using the Fields Editor as with any other dataset. To access the fields
480    editor for a TIBTable component, double click on the component. The fields editor
481    is then displayed.
483 28. TIBDatabaseInfo: new properties/function
484     * DateDBCreated (returns date/time database created)
485     * TransactionCount (returns no. of active transactions)
486     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
487     * PagesFree (Firebird 3 or later)
488     * PagesUsed (Firebird 3 or later)
489     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
490     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
492 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
494 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
496 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
497    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
499 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
500    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
501    firing during backup and restore.
503 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
504    for verbose output using the new property "StatisticsRequested".
505    see
507 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
509 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
510    palette. This uses the online validation feature added in Firebird 2.5. The
511    services's properties enable inclusion/exclusion of tables and indexes using
512    regular expressions. See.
515 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
516    option on a database.
518 37. TIBCustomService: Assign method implemented to allow copying of service login
519    context between service API components. "Detach" method now only detaches
520    service when last reference to the service interface detaches. Tidy up of
521    code for SetActive and Attach methods including password hiding.
523 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
524    and used to determine the auth method and protocol used for the connection.
526 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
527    a Create Database Statement generated by IBX.
529 40. All IBServices now have an additional published property "PortNo". This may
530    be set to a non-standard port number when necessary. If zero then the default
531    port number is used.
533 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
534    and not just the mouse.
536 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
538 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
539    image index and selected image index for each node to be set from a database field.
541 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
542    then database schema includes grants to all users. If not present then the
543    only user grants included are those to User PUBLIC.
545 45. TIBTreeView: performance improvement. When expanding include both expanded node
546    and child nodes in dataset.
549 IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
551 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
552   changes.
554 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
555   Bug could result in truncated multi-byte character set values.
557 3. Changes consequential on moving fbintf character set utility functions from
558   IFirebirdAPI to IAttachment.
560 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
562 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
563   results in autocomplete ignoring prefix text.
565 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
566   entering a new name into the text box.
568 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
569   Firebird rather than recomputing it.
571 8. Property Editor positioning tidy up: All IBX Property editors should now be
572   screen centre. Previously some were "poDesigned" which may be inappropriate
573   for multi monitor desktops.
575 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
577 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
578    a transaction and always reset the object.
580 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
582 13. TIBXScript: Allow for override of database filename in Create Database statements.
584 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
585    to a gbak format archive.
587 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
589 16. IBLocaldb: Drop database if error creating an empty database.
591 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
592    unless selected node not in current dataset.
594 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
595    to TIBCustomService, and IBlocalDB code tidy up.
597 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
598    behaviour due to uninitialised variable.
600 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
601    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
603 21. IBSQL: When Database changed ensure that all resources are freed.
605 22. IBCustomDataset: When database changed ensure that queries an unprepared.
607 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
608    * Line Wrap on SQL Token boundaries (on user command)
609    * auto-complete table names in drop down list of table names
610    * Double click on tablename or field name adds to SQL text
612 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
614 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
615    TVariantArray. Seems to avoid memory corruption in Windows (probably a
616    workaround for a problem in fpc 3.0.4 win64).
618 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
620 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
622 IBX Change Log  version                   (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
624 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
625   include remote system name.
627 2. TIBExtract: No longer include comment header and COMMIT statement for empty
628   tables when data included in output.
630 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
631   and timing information to be written to stdout. This may be used to locate
632   performance bottlenecks.
634 4. SQLParser: only call "OnChanging" event handler when value is different.
636 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
638 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
639   that BindFields is called when the query is next activated. Avoids FieldName
640   not found error.
642 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
643   purpose and allows the programmer to define any action they want for Update, Insert
644   or Delete. This may be complex SQL (similar to a Trigger), application specific
645   filtering of updates, or use of statements such as Grant or Revoke instead of
646   normal DML. See User Manual for more information.
648 IBX Change Log  version                  (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
650 1. TIBEvents: Fix uninitialised variable that could result in lost events.
652 2. TIBExtract: Added support for FB3 "USAGE" privilege.
654 3. TIBExtract: data formatted as Charset set "octets" is now output using
655   hexadecimal notation.
657 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
658   using a simple XML format.
660 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
661   grants to these objects.
663 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
664   dependency problems restoring complex databases.
666 7. TIBXScript: This component has been restructured to allow for the processing of
667   embedded XML in INSERT statements and to support interactive sources in addition
668   to non-interactive data sources such as files.
670 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
672 9. TIBXScript: ISQL compatiable Set statements are now supported:
674   SET TERM
676   SET BAIL
677   SET ECHO
680   SET NAMES <character set>
682 10. IBVersion unit added to hold current IBX Version Number information.
684 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
685    and domain definitions.
687 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
688    fully supported.
690 13. TIBExtract: when a database dump includes data, the generator values are now also set.
692 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
694 IBX Change Log  version     (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
696 See also doc/IBX4LazarusGuide.pdf for important information on
697 upgrading to IBX2.
699 1. Size property of TIBStringField is now the width in characters of the field
700   and not the byte length. This applies only to multi-byte character sets such
701   as UTF8. The original approach aligned with TStringField. However, the TStringField
702   code is not recognised as a bug and hence this change to align the behaviour.
703   The TStringField change is expected in fpc 3.2.0.
705 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
706   true (default) then Size property value saved in the lfm is ignored. Size is
707   always set from the dynamic information read from the database. It is unclear
708   why anyone would want to override this and set Size to false.
710 3. ibxscript: should now handle correctly a Case..End statement within a procedure
711   block.
713 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
714   exist when an attempt is made to connect to it (run time only) then an attempt
715   is made to create the database.
717 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
718   has been successfully created as a result of a call to CreateDatabase or when
719   creating a database after it was found not to exist.
721 6.  DBControlGrid: a race condition could result in the wrong row image being
722    written to the cache. This has been avoided by a trip round the message
723    loop before rendering the row image.
725 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
726    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
727    known to risk corrupt rendering of row images when the control is first
728    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
729    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
731 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
732    a TDateEdit control located on an editor panel.
734 9.  TIBExtract: brought up-to-date plus many bug fixes.
736 10. DBControlGrid: Removed memory leak when updating rows.
738 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
740 IBX Change Log  version                                           (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
742 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
743   when target codepage is CP_NONE. This is a workaround for
746 2. DBLog option removed from TIBStatisticalService - not supported by server
747   since Firebird 1.5.
749 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
750   similar.
752 4. IBCodePage: updated mapping between codepages and character id.
754 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
755   Firebird. Character sets with a char width of two are not UTF16.
757 6. Strings received from the database are now always transliterated into UTF8
758   regardless of the database character set or connection character set. This
759   is for compatibility with the LCL.
761 IBX Change Log  version  (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
763 1. IBBlob: Defer reading of blob until read method called. This avoids having to
764   read in an entire blob just to get the size of the blob. General performance
765   improvement when opening datasets containing blobs.
767 2. Clearing a  Blob now sets the corresponding field's modified flag.
769 3. IBLookupCombo: When not performing auto-complete, original query sort order
770   is now used.
772 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
773   determined.
775 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
777 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
778   lazarus 1.6.0
780 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
781   compilation error.
783 IBX Change Log  version                                 (1.4-1) Tue, 17 May 2016 09:14:51 +0100
785 1. No character set specified for connection: when a text blob is retrieved, the
786  character set is determined by looking up the native character set using then
787  Firebird API. Otherwise a text mode blob is assumed to have the same character
788  set as the connection.
790 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
791   for Login Dialog returing a change to the database path.
793 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
794   to be changed from that given in the TIBDatabase/TIBServer component and for the
795   entered value to be saved on a project specific basis (design time only).
797 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
798   column fieldname. If they are the same then it is acts as a look up for the KeyValue
799   Otherwise, it sets the column text to the selected ListField Value.
801 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
802   column width.
804 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
805   and a case insensitive search is requested.
807 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
808   or column ListSource.
810 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
811   unprepare) when closing and the text has not changed.
813 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
814   Less likely to cause a cursor re-use error on Windows.
816 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
817   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
819 11. TIBTreeView: Guard against nil destination on record changed
821 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
822    string type with the code page set to reflect the returned field encoding after
823    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
824    earlier versions.
826 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
827    will now result in transliteration to the code page specified for the Firebird driver
828    if the assigned string has a different code page. FPC 3.0.0 onwards only.
830 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
831    is ignored and the lc_ctype value, when the database is opened, is set to align with
832    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
833    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
834    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
835    the GETACP is used to determine the Windows code page.
837 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
838    name used as the lc_ctype when the database was opened. Only valid while the
839    Database is connected.
841 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
842    id that corresponds to the DefaultCharSetName.
844 IBX Change Log  version                          (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
846 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
847   path is given and database attach fails due to access permission issues on the
848   temp directory or security database, then the attach is retried with "localhost:"
849   prefixing the databasename. This should avoid problems when the database has to
850   be accessed by a local (e.g. classic) server and libfbembed is used.
852 2. Windows: revised search order for Firebird DLL:
853     i.   The Firebird Embedded Server in the application Directory.
854     ii.  If the FIREBIRD environment variable is set then the directory this
855          points to is searched for the FB Client DLL and then then underlying
856          "bin" directory.
857     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
858          is used to locate the Firebird installation directory and the underlying
859          "bin" directory is searched for the FB Client DLL.
860     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
861          are searched for the FB Client DLL.
862     v.   The PATH Environment variable is used to search for the FB Client DLL.
863     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
865 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
866   See doc/readme.scriptengine and example applications.
868 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
869   simplify the use of the embedded firebird server on both Linux and Windows platforms.
870   See dpc/readme.localdatabase and example applications.
872 5. IBDynamicGrid: Reordering on column header click should now also work for
873   dynamic columns.
875 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
876   between incrementing/decrementing the lock count and signalling the event.
878 IBX Change Log  version           (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
880 1.3.2 was never formally released and only made available as beta copies.
882 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
884 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
886 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
888 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
889   i.e. when it is a calculated field
891 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
892   This problem was due to a race condition between recalculating row heights and
893   determining which row was selected by the mouse click. The row height calculation
894   is now deferred by an extra trip round the message loop allowing the row to
895   be always calculated on the current grid layout rather than risking it being
896   calculated on the grid layout after the expanded row has been shrunk.
898 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
899   Windows.
901 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
902   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
903   to be determined at runtime. See doc/readme.charactersets.html.
905 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
906   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
908 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
909   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
910   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
912   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
913   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
914   implies no truncation.
916 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
918 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
919   (avoids "Not in Edit Mode" error).
921 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
923 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
924    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
926 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
928 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
930 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
932 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
934 IBX Change Log  version        (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
936 1.   OnCloseUp Event Handler added to TDBLookupProperties
938 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
939     problem with row size when exception is called.
941 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
943 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
944     in a TCustomComboBox and ignores return key if in a TCustomMemo
946 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
947     keyed in i.e. when autocomplete not performed
949 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
950     console mode applications with all LCL required functions (builtin dialogs and
951     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
952     not included in your project, IBX should compile and link with a console mode program.
953     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
954     console mode application or the IDE will automatically assume that your
955     application is GUI based. Instead, you should include the ibexpressconsolemode package.
957     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
958     to use the built in dialogs and cursor management. IBDialogs is
959     included by default if "ibexpress" is in your project source's "uses" clause.
960     This should be the case for all projects created through the IDE. This is why
961     you do not want to add the ibexpress package to console mode applications. The
962     ibexpressconsolemode package has been created to allow console mode programs
963     to avoid adding LCL dependencies when using IBX, while still having the
964     unit search paths set up correctly.
966     Existing users should check to ensure that the "ibexpress" unit is included in
967     each project's source file (*.lpr).
969     You may find that in order for the IDE to recognise that ibexpressconsolemode
970     exists, you have to first open the package in the IDE and then close it. This
971     adds it to the most recently accessed packages list. To make it permanently
972     available, add the package name to lazarus' file.
974         Thanks to Julio Jiménez for suggesting support of console mode.
976 7.   SQL Parser can now accept quoted strings that include new lines
978 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
979     of text on start of edit. This is particularly useful when tabbing to a
980     column and then inserting text.
982 9.   New Examples provided for IB Services and ISQLMonitor.
984 10. Fix error when writing to blob streams that recorded only the last buffer
985    write in the blob stream. In most cases, this did not cause a problem as the
986    IB Blob Stream is written in a single write. However, with the TDBImage, write
987    of a graphic type prefix was lost which caused a problem when the image could
988        not be automatically recognised.
990 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
991    already open" errors due to random numbers used for the cursor name being identical.
993 12. IBTable: corrected error that could result in an "Index out of bounds" error
994    when opening the table and the Primary Key is the last or only column in the
995    table. Thanks to Rick Hoover for the fix.
997 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
998    of "UTF-8", and update list of available database character sets. Existing
999    users should check the current lc_ctype setting in their applications.
1001 IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1003 1.  Firebird Services: avoid List Index error when opening a service with an
1004    empty Params property.
1006 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1007    Link now set up in Loaded method - avoids occasional failure to apply
1008    SQL markup on initial open.
1010 3.  "Employees" example performance improvements when scrolling.
1012 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1013    TFrame. Force recaching of selected frame to avoid GTK race (results in a
1014    random image cached).
1016 5.  DBControlGrid: Should now react to changes in panel height at run time.
1018 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
1019    even when further rows exist.
1021 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
1022    always be derived from panel height and setting this property can cause confusion.
1023    Note for existing projects: to avoid a missing property error at run time,
1024    each form using the DBControlGrid must be opened, updated and saved in the IDE
1025    in order to remove the property value from the lfm.
1028 IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1030 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1031    call Prepare before setting parameter values.
1033 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
1035 3.  Code tidyup and more robust handling of dsql information result vector.
1037 4.  Support for centralised handling of transaction status changes. TIBTransaction
1038    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1039    and "AfterExecQuery". The first three are called after the same event is called
1040    for an IBCustomDataSet descendent using the Transaction. The fourth is called
1041    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1042    enable monitoring of transaction status changes for a given transaction to be
1043    handled in a single place. For example, when a change to the dataset occurs
1044    an indicator can be set that shows the user that in order to save changes,
1045    the transaction should be committed.  Rather than doing this per dataset, this
1046    can now be done per transaction.
1048 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
1049    the dataset is scrolled. However, any changes to the current row are, by default,
1050    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1051    have a new property "DataSetCloseAction" that adds automatic posting of changes
1052    on dataset close. If this property is set to dcDiscardChanges (default) then the
1053    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1054    then IBX will attempt to post any unsaved changes before the dataset is closed
1055    (and after the BeforeClose event handler is called). The exception is when the
1056    dataset is being closed as a result of a transaction rollback. In this case,
1057    no action is taken and any unsaved  changes are discarded. This avoids both
1058    unnecessary overhead and the risk that a validation error may occur in the Post
1059    raising an exception and thereby preventing a rollback.
1061 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
1062    In earlier versions, the Display Width was set to the maximum byte width rather than the character
1063    width. Display Widths are now corrected by dividing by the max byte width per character.
1064    For UTF8 character sets, the byte width is four and hence the Display Width will be
1065    the byte width divided by 4. The byte width of each character set is determined
1066    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1067    system table. (see also
1069 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1071 8.  IBLookupComboEditBox: List should now always be restored to full list when the
1072    control loses focus. Default Key press default interval reduced to 200ms.
1074 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
1075    when dataset rows are less than visible rows.
1077 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1078    does not exist or DataSet is empty. More responsive on dataset open. New event
1079    OnRestorePosition. Column sort disabled if no header row.
1081 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1082    while dataset state is dsInsert. Avoids posting errors.
1084 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1085    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1087 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1089 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1090    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1091    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1092    always "posts" the current record regardless or whether or not it may be more appropriate
1093    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1094    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1095    as the first action of the "Post" method and allows the handler to convert the Post
1096    into a Cancel if that is the appropriate action on moving to a different row. This is
1097    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1098    raised here, but it may still be more appropriate to validate a post and signal
1099    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1101 15. On Unix derived systems, the Firebird library name can now be given as a colon
1102    separated list. Each library name on the list is tried in turn, in left to right
1103    order with the first found being used as the firebird library. By default, on Linux,
1104    the library name list is ''. This can be
1105    overidden by the FBLIB environment variable or the OnGetLibraryName function.
1107    Note: when using the, if you prefix the database name with "localhost:"
1108    then it will still attempt to access the database via the Firebird Server and will
1109    require a username and password. If only the pathname is given, then the username
1110    and password should be omitted and the unix file permissions are used to grant
1111    access.
1113 IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1115 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1116    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1117    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1118    corresponds to a row of the linked DataSource. Any data aware control on the
1119    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1121 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1122   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1123   takes place during database access. This may be useful when there are performance issues with
1124   the change of cursor. Setting the property to false suppresses the change of cursor.
1126 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1127   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1128   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1129   making all changes permanent immediately rather than when the transaction is explicitly
1130   committed.
1132 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1133   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1135 IBX Change Log  version      (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1137 Development version only.
1139 IBX Change Log  version   (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1141 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1142   This is typically used during an "OnBeforeOpen" event handler to manipulate the
1143   "Where" and "Having" clauses to implement user specified filters of arbitrary
1144   complexity.
1146 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1147   three new data aware controls dependent on IBX and which make use of the SQL Parser.
1148   These are:
1150   - TIBLookupComboEditBox
1151   - TIBDynamicGrid
1152   - TIBTreeview
1154   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1155   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1156   to revise the available list and restrict it to items that are prefixed by the
1157   typed text (either case sensitive or case insensitive). Autoinsert allows a
1158   newly typed entry to be added to the list dataset and included in the available
1159   list items.
1161   TIBDynamicGrid is a TDBGrid descendent that provides for:
1162   - automatic resizing of selected columns to fill the available row length
1163   - automatic positioning and sizing of a "totals" control, typically at the
1164     column footer, on a per column basis.
1165   - DataSet resorting on header row click, sorting the dataset by the selected column.
1166     A second click on the same header cell reversed the sort order.
1167   - Support for a "Panel Editor". That is on clicking the indicator column, the row
1168     is automatically expanded and a panel superimposed on it. The panel can have any
1169     number of child controls, typically data aware controls with the same datasource
1170     as the grid allowing for editing of additional fields and more complex editors.
1171   - Reselection of the same row following resorting.
1172   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1173     Its properties are specified on a per column basis and allows for one or more
1174     columns to have their values selected from a list provided by a dataset.
1175     Autocomplete and autoinsert are also available. The existing picklist editor
1176     is unaffected by the extension.
1178   TIBTreeView is a data aware TCustomTreeView.
1180 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1181   zero scale will no longer return an error. An Int64 will be returned instead.
1183 4. TIBTransaction now has events for Before and After Transaction End and a new function
1184   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1186 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1187   repeated multiple times.
1189 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1190   check used to get in the way of using Stored Procedures, and "Update or Insert"
1191   statements.
1193 7. Insert, Modify and Delete property Editors now support Query Generation from
1194   Stored Procedures.
1196 8. Three new examples illustrate the use of the new IB Controls
1199 IBX Change Log  version  (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1201 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1202   setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1203   Gabor Boros for reporting this problem and for testing the improvements).
1205 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1206   See readme.field+param.names in the doc folder.
1208 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1209   dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1211 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1213 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1214   actions.
1216 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1217   thanks to Yuriy Kopnin for pointing this out).
1219 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1221 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1222   for both fields and parameter setting.
1224 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1225   visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1227 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1228    when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1230 11. TIBTable now has a property editor for "MasterFields"
1232 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1233    GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1235 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1236    of settings is unrecognised. Selecting this radio button has no effect on the settings.
1239 IBX Change Log  version                 (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1241 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1243 IBX Change Log  version          (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1245 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1246   it is null. This allows for alternative user defined setting of the generator
1248   Many thanks to Julio Jiménez for this fix
1250 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1251   and suggests that the user may have forgotten to install it.
1253 IBX Change Log  version         (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1255 1. Conditional compilation used to limit registration of TIntegerField to
1256   Lazarus versions less than 1.1
1258 2. When a database connection is created, character set is now by default set
1259   to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1260   1250 to 1254.
1263 IBX Change Log  version     (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1265 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1268 IBX Change Log  version    (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1270 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1271   Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1273 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1274   package is changed to do this (which it should do).
1276 IBX Change Log  version (1.0-0)  Sat, 28 Apr 2012 16:43:00 +0100
1278 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1280 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1282 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1284 4. Property editors should now correctly resize.
1286 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1287   (restored original functionality)
1289 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1290   library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
