The recent release of Firebird version 2.1.1 is very welcome.
Here are a few of the fixes I consider important for 2.1 production servers and so recommend the update:
- Stability fixes for the monitoring tables
- Fixed possible corruption of the users database, security2.fdb.
- Fixed nBackup, which did not work in version 2.1.
- Fixed a memory leak on DDL statements.
The complete list of bugs fixed and the downloads are at the Firebird SQL website.
