Updating Kimai


Roadmap and releases

You can see a rough development roadmap in the Milestones sections. It is open for changes and input from the community, your ideas and questions are welcome.

Kimai 2 uses a rolling release concept for delivering updates. You can upgrade Kimai at any time, you don't need to wait for the next official release. The master branch is always deployable, release tags are only snapshots of the current development version.

Release versions will be created on a regular base (approx. one release every 2 months). Every code change, whether it's a new feature or a bugfix, will be done on the master branch. Kimai is actively developed in my spare time, I put my effort into the software instead of backporting changes.
