| 5 | ----------------------- |
| 6 | |
| 7 | The project currently aims to do a release once every 6 months which will be |
| 8 | tagged on the master branch. There will be a code freeze (stop merging |
| 9 | non-essential PRs) up to 4 weeks prior to the target release date. The release |
| 10 | candidates will start appearing after this and only bug fixes or updates |
| 11 | required for the release will be merged. The maintainers are free to use their |
| 12 | judgement on what PRs are essential for the release. A release branch may be |
| 13 | created after code freeze if there are significant PRs that need merging onto |
| 14 | the integration branch during the merge window. |
| 15 | |
| 16 | The release testing will be performed on release candidates and depending on |
| 17 | issues found, additional release candidates may be created to fix the issues. |
