- 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 changes) 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 changes are essential for the release. A release branch may be
- created after code freeze if there are significant changes 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.

- Version numbering
- ~~~~~~~~~~~~~~~~~
- TF-A version is given in Makefile, through several macros:
- - VERSION_MAJOR
- - VERSION_MINOR
- - VERSION_PATCH
- For example, TF-A v2.10 has VERSION_MAJOR=2, VERSION_MINOR=10 and VERSION_PATCH=0.
- This VERSION_PATCH macro is only increased for LTS releases.
- Upcoming Releases
- ~~~~~~~~~~~~~~~~~
- These are the estimated dates for the upcoming release. These may change
- depending on project requirement and partner feedback.
