Property Editors now automatically include System Tables when opened and when the query table + is a System Table. + +22. IBServices: SQRB and SRB buffers are now reset when service query throws and exception. + This avoids errors due to a stale SQRB or SRB being used for the next query. + +23. IBServices: Service attach parameters now include "expected_db". This is used to + add the SPB item isc_spb_expected_db. This names a database using + an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a + database. examples/services re-written to illustrate use of "expected_db". + +24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout. + This avoids truncated backups when the server returns a timeout (busy) response. + +25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase. + +26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local + databasenames. These are respectively expanded to the local system's temp directory + (including trailing delimiter) or to a directory a prescribed data directory (including + trailing delimiter). Under Unix systems the data directory is a hidden directory + in the user's home directory. The hidden directory name is either the string returned + from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'. + Under Windows, the directory is the same as the Data Directory as decribed + above but instead prefixed by the User's application data path. These may be + used to improve application portability. + +27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef + this has not worked for a long time and is not useful either. FieldDefs should be + managed using the Fields Editor as with any other dataset.

TIBDatabase: new proterties: AuthenticationMethod and RemoteProtocol. Read only + and used to determine the auth method and protocol used for the connection. + +39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using + a Create Database Statement generated by IBX. + +40. All IBServices now have an additional published property "PortNo". This may + be set to a non-standard port number when necessary. If zero then the default + port number is used. + +41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard + and not just the mouse. + +42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added. + +43.
