25.3.1

Summary

Hello community! We're excited to announce the release of ArcadeDB 25.3.1 early in the month. This release contains a MAJOR CHANGE in the storage engine: fully reusage of the deleted space in the database and recycling of record ids (RIDs). All ArcadeDB releases are 100% compatible with the previous ones in terms of database format, so there is no need to upgrade the database or export/import it for the upgrade, but please make a backup/copy of your database before upgrading.
