Where can I download the 2.3.0 version , under archive I cannot find it. I need this because it is the only version which works with my very old SQLBASE database.
We don't have an archive for so old versions. Potentially it is possible to build any version from sources but it will take too much time because build procedure/environment was significantly changed since then. What actual problems don't let you to use recent DBeaver version with your database? I'm sure that it'll be easier to fix recent version than to try to resurrect the old one.
