This release contains no breaking changes.

## Database migrations

This release includes three database migrations to facilitate asset storage improvements. All migrations are expected to run fast and won’t prevent Document Engine rollback to older versions in the existing installations, unless storage backend overriding is used.

## Asset storage configuration changes

This release includes changes to how fallback storage backends are configured. Specifically, in addition to setting `ENABLE_ASSET_STORAGE_FALLBACK` to `true`, it’s also necessary to enable the individual storage backends that should serve as fallbacks by setting one or more of the following to `true`:

- `ENABLE_ASSET_STORAGE_FALLBACK_POSTGRES`

- `ENABLE_ASSET_STORAGE_FALLBACK_S3`

- `ENABLE_ASSET_STORAGE_FALLBACK_AZURE`

By default, the configuration options above will be set to `false`.
