Ref: https://linaro.atlassian.net/browse/TFC-669 The initial LTS document was created as pdf and was maintained in a shared folder location, to avoid pdf getting lost and trying to find where it is we decided to have LTS details part of docs in TF-A. This patch directly reflects the data from pdf attached to TFC-669. Any improvements or amends to this will be done at later phases based on LTS maintainers comments and agreements.

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 :ref:`LTS - Long-Term Support` releases.
|
|
|
|
