The months that have passed since the initial release have seen numerous Tracker issues tackled to address things that have been reported broken, bent, or compromised in v.2.5. As well as a long list of bugfixes, a few minor improvements have been made.
The primary goal for Firebird 2.5 was to establish the basics for a new threading architecture that is almost entirely common to the Superserver, Classic, and Embedded models, taking in lower level synchronization and thread safety generally. User management is accessible through SQL CREATE/ALTER/DROP USER statements, and syntaxes for ALTER VIEW and CREATE OR ALTER VIEW are implemented. PSQL improvements include the introduction of autonomous transactions and the ability to query another database via EXECUTE STATEMENT.

This release fixes various bugs. The server could stop responding to a particular client attachment under some conditions. There would be a small time window during which the remote server would ignore the incoming operation request it had just received and, thereby, seem to block the client application. The listener thread would remain operational, but the client would be synchronously waiting for the reply packet that would not come.
