Although Firebird 2.5 has reached End of Life, many production systems
still depend on it. Following the disclosure of several security
vulnerabilities that also affect Firebird 2.5, IBPhoenix has introduced a
Firebird 2.5 Maintenance Subscription for commercial users. Subscribers
receive security-patched Firebird 2.5 builds based on the final
official release, together with future security updates released during
the subscription period.
For full details, including supported platforms, pricing, available maintenance options, and subscription information, see the
Firebird 2.5 Maintenance Subscription product page.
