Hello, The following bug has been fixed on edk2/master https://bugzilla.tianocore.org/show_bug.cgi?id=3111 https://github.com/tianocore/edk2/pull/1226 This bug is also considered a critical bug against edk2-stable202011. The behavior of the Variable Lock Protocol was changed in a non-backwards compatible manner in edk2-stable202011 and this is impacting some downstream platforms. The following 2 commits on edk2/master restore the original behavior of the Variable Lock Protocol. https://github.com/tianocore/edk2/pull/1226/commits/893cfe2847b83da74f53858d6acaa15a348bad7c https://github.com/tianocore/edk2/pull/1226/commits/16491ba6a6e9a91cedeeed45bc0fbdfde49f7968 The request here is to create a supported branch from edk2-stable202011 tag and apply these 2 commits as critical bug fixes on the supported branch. Since we started using the edk2-stable* tag process, there has not been a request to create a supported branch from one of those tags. As a result, there are a couple opens that need to be addressed: 1) Supported branch naming convention. Branch Proposal: stable/ Branch Example: stable/202011 2) CI requirements for supported branches. Proposal: Update .azurepipelines yml files to trigger on stable/* branches, update .mergify configuration file to support merging of stable/* branches, and update GitHub branch protection settings to protect stable/* branches. 3) A stable/* branch is only supported until the next edk2-stable tag release. 4) Release requirements for supported branches. Proposal: If there are a significant number of critical fixes applied to a stable/* branch, then a request for a release can be made that would trigger focused testing of the supported branch and creation of a new release. If all testing passes, then a tag is created on the stable/* branch and a release is created on GitHub that summarizes the set of critical fixes and the testing performed. Tag Proposal: edk2-stable. Tag Example : edk2-stable202011.01 Please let me know if you have any feedback or comments on this proposal. The goal is to close on this topic this week. Thank you, Mike
