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. + +:: + + |<----------6 months---------->| + |<---4 weeks--->| |<---4 weeks--->| + +-----------------------------------------------------------> time + | | | | + code freeze ver w.x code freeze ver y.z + + +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.
