Production Docker images now use a non-root user with UID 1000 and GID 1000.
That change was made in v1.20.0, reverted in v1.20.1, and will be re-introduced in a future release.

This release adds support for capped collections. They can be created as usual using create command. Both max (maximum number of documents) and size (maximum collection size in bytes) parameters are supported.
This release adds support for tailable cursors. Both tailable and awaitData parameters are supported.
This release adds support for the basic OpLog functionality. The main supported use case is Meteor's OpLog tailing. Replication is not supported yet.
OpLog collection does not exist by default. To enable OpLog functionality, create a capped collection oplog.rs in the local database. Setting replica set name using --repl-set-name flag / FERRETDB_REPL_SET_NAME environment variable might also be needed.

That's a preparation for providing artifacts for other OSes.

As mentioned in the previous release changes, the old PostgreSQL backend code is completely removed. PostgreSQL remains our main backend, just with a new code base.

The new PostgreSQL backend is now enabled by default. You can still enable the old backend with --postgresql-old flag or FERRETDB_POSTGRESQL_OLD=true environment variable, but it will be removed in the next release.
Our Docker images (but not binaries and .deb / .rpm packages) now use /state directory for the SQLite backend.
That directory is also a Docker volume, so data will be preserved after the container restart by default.
arm/v7 packagesWe now provide linux/arm/v7 binaries, Docker images, and .deb / .rpm packages.
