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