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. + +:: + + |<----------6 months---------->| + |<---4 weeks--->| |<---4 weeks--->| + +-----------------------------------------------------------> time + | | | | + code freeze ver w.x code freeze ver y.z + + +Upcoming Releases +~~~~~~~~~~~~~~~~~ + +These are the estimated dates for the upcoming release.
