Release Notes

This page describes the changes for each component: 'core', 'ui', and the various centrally-maintained plugins and client libraries. For each, a table is presented with version number, notable new features, notable pull requests, and any dependencies.

For more information about the structure and architecture of the code, please see our technical architecture pages.

We use Semantic Versioning for all repositories, please note that anything labelled with -SNAPSHOT is under development and should be considered potentially unstable.

In our code repositories, we use Git Flow, and so the 'main / master' branch may be considered stable, but 'bleeding edge' features may be available within 'develop' or any feature branch.

Please see our Installing Plugins pages for details about build artefacts and dependencies.

The current full release is 2023.1 (a.k.a B5.3.0_F7.3.0).
