What's Changed

We are pleased to announce our first Beta release!

Storage changes for PostgreSQL

We made a few backward-incompatible changes in the way we store data in PostgreSQL to improve FerretDB performance. In the future, those changes will allow us to use indexes and query collections faster.

To keep your data:

• backup FerretDB databases using mongodump or mongoexport;
• backup PostgreSQL database using pg_dump or other tool (just in case);
• stop FerretDB;
• drop PostgreSQL views for FerretDB databases;
• start FerretDB 0.8;
• restore databases using mongorestore or mongoimport.

Authentication

It is now possible to use the backend's authentication mechanisms in FerretDB. See documentation.
