Migration

Storages created or modified by version 4.0.0 are not backwards compatible with older versions. Once a storage has been opened with version 4.0.0, it most likely cannot be used with prior versions anymore. Make sure to create a backup of your storage before migrating.

Storages created with one of the 4.0.0 beta versions that use the vector index are unfortunately not compatible with the final version due to necessary internal changes. These storages need to be recreated with the final 4.0.0 release.
