Tagged versions and Changelog

There are different tagged versions on the Janus repository. We usually tag a new version any time a breaking change and/or a set of comprehensive changes and fixes is going to be merged/applied to Janus, and so the Changelog below can act as a simple and quick summary of which changes are available in each version.

It's very important to point out, though, that tagged version are NOT to be considered stable versions. This is a common misunderstanding. The only version we consider stable is master as it's the only branch where we continuously provide fixes and enhancements: this is particularly important in the WebRTC world, where it's not uncommon to see features breaking overnight due to changes in how browsers and other WebRTC devices implement things. As such, again, a tagged version is only a way to take a snapshot of where Janus was at a specific point in time, and before a more or less major change occurred. While you're free to stick to tagged versions for your deployments (e.g., because that's how provisioning is usually done in your company), please notice we will ignore issues and reports addressing any other branch that is not master: due to lack of time and resources, we simply cannot go and investigate issues we may have fixed already, so if you're experiencing issues, make sure you can replicate them on master as well first.
