v2.1.0 (2025-04-03)

This version works only with DocumentDB v0.102.0-ferretdb-2.1.0.

Breaking changes

Caution

Please note that due to incompatibilities in our previous releases, DocumentDB can't be updated in place, even with a manual ALTER EXTENSION UPDATE query or other means. A new clean installation into an empty data directory/volume is required. All data should be backed up with mongodump/mongoexport before and restored with mongorestore/mongoimport after. See our blog post for more details.

We expect future updates to be much smoother.

What's Changed

Docker images

Docker images are again available on Docker Hub and quay.io (although we recommend using GitHub Packages).

Embeddable Go package

Once again, FerretDB can be used as a Go library.
