1Release Processes 2================= 3 4Project Release Cadence 5----------------------- 6 7The project currently aims to do a release once every 6 months which will be 8tagged on the master branch. There will be a code freeze (stop merging 9non-essential changes) up to 4 weeks prior to the target release date. The release 10candidates will start appearing after this and only bug fixes or updates 11required for the release will be merged. The maintainers are free to use their 12judgement on what changes are essential for the release. A release branch may be 13created after code freeze if there are significant changes that need merging onto 14the integration branch during the merge window. 15 16The release testing will be performed on release candidates and depending on 17issues found, additional release candidates may be created to fix the issues. 18 19:: 20 21 |<----------6 months---------->| 22 |<---4 weeks--->| |<---4 weeks--->| 23 +-----------------------------------------------------------> time 24 | | | | 25 code freeze ver w.x code freeze ver y.z 26 27 28Upcoming Releases 29~~~~~~~~~~~~~~~~~ 30 31These are the estimated dates for the upcoming release.
