FerretDB v.1.6.0 - minor release

We've just released FerretDB v1.6.0 which comes with a couple of new features, bug fixes, and enhancements to FerretDB, especially the implementation of the ping command and getParameter method for the SQLite backend.

In this release, we've also made several optimizations and resolved issues with some of the previously implemented commands, our integration tests, and among others.

For instance, in the new release, we've made significant improvements to how we handle cursors through the implementation of the killCursors command, which should help optimize cursor management, and ensure better resource management and performance.

Let's check out other notable changes in this release!

New features

In recent weeks, our team has been working to improve the existing beta support for SQLite backend, and now we've added support for the ping command and getParameter method in this release. We're thrilled with these additions and hope you'll find them useful.

Bug fixes and enhancements

In previous versions, attempting to update a document using the $set operator with the same _id value resulted in an error. We've addressed this issue in the latest release; you can now update a document without encountering an error by executing a command like db.collection.updateOne({_id: 1}, {$set: {_id: 1, a: 1}}).

We've also resolved a bug with the findOne() query, which wasn't correctly translated to the corresponding PostgreSQL query, and also resulted in a significant delay.

Other changes

As we previously mentioned in the last release, FerretDB will no longer support the Tigris backend. If you wish to continue using Tigris, please do not update FerretDB beyond v1.5.0. Earlier FerretDB releases with Tigris support are still available on GitHub here.

We also added more setup instructions for the backend for SQLite in our
