We are happy to announce the release of Jaybird 5.0.7. This release provides a number of performance improvements to blob handling, and some bug fixes.

We plan to offer more blob performance improvements in upcoming releases of Jaybird 5, for Firebird 5.0.3 and higher (see also New Article: Data access methods used in Firebird).

The following has been changed or fixed since Jaybird 5.0.6:

• Improvement: backported deferred blob open optimization from Jaybird 7 (#841)
• Fixed: NullPointerException in getGeneratedKeys() with blob columns after (auto)commit (#846)
• Fixed: Fetch response with status=0 (FETCH_OK) and count=0 was logged on DEBUG as an unexpected response (#848)
• Improvement: backported performance improvements for blob reading and writing from Jaybird 6 (#850)
• Improvement: backported fetching all known blob info items on open from Jaybird 7 (#852)
• Dependency update: updated net.java.dev.jna:jna-jpms from 5.15.0 to 5.17.0 (used by native and embedded protocols) (#855)

Jaybird 5 supports Firebird 2.5 and higher, on Java 8, Java 11, Java 17, Java 21, and Java 24 (support for Java 11 and higher using the Java 11 version of the driver).

Bug reports about undocumented changes in behavior are appreciated. Feedback can be sent to Firebird-java or reported on the issue tracker https://github.com/FirebirdSQL/jaybird/issues.
