What's new in this version:
Core Engine/API:
- The internal record compression routines exhibited some bugs
- A SELECT statement incurred more non-indexed reads in the third v.2.5 release candidate than the same statement in v.2.1.3
- ALTER DOMAIN was not possible in a database that had been migrated from an earlier version
- The WAIT mode and lock timeout parameters for the external transaction of EXECUTE STATEMENT were not matched to the corresponding parameters of the local transaction
- A regression introduced with the fix for CORE-2893 caused double processing of nodes when preparing a statement, prompting an abort to occur in the debug build
- Parameters would not work with NOT IN from a selectable stored procedure
- Incorrect LEFT JOIN result using table and derived constant subquery
- Attempt to run EXECUTE STATEMENT on an external data source failed when the data source was an InterBase 4.1 (ODS 8) database
- Batch inserts were noticeably slowed down if they were all executed in a single transaction and involved triggers that posted events
Server Crashes:
- The server would crash when isc_dql_exec_immed3_m() was called for CREATE DATABASE ... in a NULL transaction
Command-line Utilities:
- The gsec utility was sending its output list of users to stderr instead of stdout

What's new in this version:
- The default authentication method on Windows platforms is no longer mixed. It has been changed to native. For more information, see the notes on the configuration parameter Authentication.
- A fix in Firebird 2.5 that alleviates the “hogging” behaviour of the nBackup utility has been backported to this patch release. For more information, see the Improvement in V.2.1.3 note in the nBackup section of the Utilities chapter.
- By popular request, Dmitry Yemanov adds some helpful performance guidelines pertaining to the “internals” of the database monitoring system (a.k.a. “MON$”). The purpose is to assist those using this facility on heavily loaded systems to employ it in ways that provide the information you want while minimising its impact on the end-user experience.
