This is a ‘fix’ release that includes fixes for Valentina Studio and Valentina Server, both of which are included in Omegabundle for Xojo 2022.
Also, if you didn’t read the Release 12.5 notes, note that the ValentinaDB format has been updated in order to leverage the huge improvements to BLOB object handling. If you open a ValentinaDB database with Valentina Studio 12.5 or higher, your database will be silently updated to the new format.
