11Project Release Cadence
12-----------------------
13
14The project currently aims to do a release once every 6 months which will be
15tagged on the master branch. There will be a code freeze (stop merging
16non-essential PRs) up to 4 weeks prior to the target release date. The release
17candidates will start appearing after this and only bug fixes or updates
18required for the release will be merged. The maintainers are free to use their
19judgement on what PRs are essential for the release. A release branch may be
20created after code freeze if there are significant PRs that need merging onto
21the integration branch during the merge window.
22
23The release testing will be performed on release candidates and depending on
24issues found, additional release candidates may be created to fix the issues.
