TF-A Release Information ======================== 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. |<----------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.
