This is a separate note related to the ValentinaDB database format to any release announcement.
Some improvements were introduced in release 12.4 and 12.4.4 to dramatically improve BLOB performance and those releases did not involve an update to the actual format.
ValentinaDB Release 12.5 does introduce changes to the database format. If you open your ValentinaDB database in Valentina Studio 12.5, it will silently update your database to the new format.
We strongly encourage you to create backups of your ValentinaDB files in the previous format before upgrading to Valentina 12.5 as there is no mechanism to roll back to the old format.
