Joel Hutton4fe91232019-02-25 15:18:56 +00004Project 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
laurenw-arme69f3502019-10-16 16:32:16 -05009non-essential changes) up to 4 weeks prior to the target release date. The release
Joel Hutton4fe91232019-02-25 15:18:56 +000010candidates 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
laurenw-arme69f3502019-10-16 16:32:16 -050012judgement 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
Joel Hutton4fe91232019-02-25 15:18:56 +000014the 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.

Yann Gautier3e56c692023-10-04 18:59:44 +020028Version numbering
29~~~~~~~~~~~~~~~~~
30TF-A version is given in Makefile, through several macros:
31
32- VERSION_MAJOR
33- VERSION_MINOR
34- VERSION_PATCH
35
36For example, TF-A v2.10 has VERSION_MAJOR=2, VERSION_MINOR=10 and VERSION_PATCH=0.
37
38This VERSION_PATCH macro is only increased for LTS releases.
