What's Changed

This release provides beta-level support for the SQLite backend. There is some missing functionality, but it is ready for early adopters.

This release provides improved cursor support, enabling commands like find and aggregate to return large data sets much more effectively.

Tigris data users: Please note that this is the last release of FerretDB which includes support for the Tigris backend. Starting from FerretDB v1.6.0, Tigris will not be supported. If you wish to use Tigris, please do not update FerretDB beyond v1.5.0. This and earlier versions of FerretDB with Tigris support will still be available on GitHub.
