DBeaver nutzt für Firebird den Jaybird Treiber. In der Release Notes zu Jaybird heißt es:
"At the time of release of Jaybird 4, Firebird 4 was still in testing. As a result, support for Firebird 4 is tentative. There can be incompatibilities with features or changes after Firebird version 4.0.0.1803 (Jaybird 4.0.0), 4.0.0.2143 (Jaybird 4.0.1), or 4.0.0.2325 (Jaybird 4.0.2). Once Firebird 4 is released, incompatibilities or otherwise breaking changes will be addressed in a point release of Jaybird 4."
IBExpert spricht Firebird 4 schon seit längerem an (alles andere wäre auch merkwürdig...
)
