We are happy to announce the first release of Jaybird 6.
Jaybird 6 is — from a JDBC perspective — an incremental change from Jaybird 5.
However, internally, Jaybird underwent some major changes, the biggest was splitting off the native and embedded protocols to a separate plugin artifact (jaybird-native).
The major changes and new features in Jaybird 6 are:
Minimum supported Java version is Java 17.
See Java support for more information.
Minimum supported Firebird version is Firebird 3.0.
See Firebird support for more information.
The pure Java protocol — by default --no longer connects to Firebird 2.5 and older, as those versions are not supported.
See Pure Java will not connect to unsupported Firebird versions by default for more information.
The native and embedded protocols have been moved to a separate artifact, jaybird-native.
See NATIVE and EMBEDDED support moved to a separate artifact for more information.
… and other fixes and changes
Upgrading from Jaybird 5 should be straightforward, but please make sure to read Compatibility changes before using Jaybird 6. If you’re using Jaybird with the native or embedded connections, you will need to make some additional changes. See also Upgrading from Jaybird 5 to Jaybird 6.
Bug reports about undocumented changes in behavior are appreciated. Feedback can be sent to the Firebird-java mailing list or reported on the issue tracker https://github.com/FirebirdSQL/jaybird/issues.
