Branch cut V8 12.6 on 2024-05-13
Lutz Vahl
Hi,
It is time again. If you have any questions regarding the release, please ping this thread.
FRIDAY 2024-05-10: API adoption freeze starts.
V8 will branch on MONDAY for the upcoming Beta phase for Chrome 126. On the 2024-05-10 one of the latest Canaries will be selected to be the branch backup candidate in case of any issues on the branch day.
In order to make this synchronization as painless as possible for V8 and Blink, please don't make API changes which make the revert more difficult and don't adopt API changes. When in doubt, ask vahl@.
FRIDAY 2024-05-10: Select backup candidate for branching
Decide if the latest Canary can be taken as a backup candidate for branching. If this is not the case the Canary needs to be stabilized ASAP.
MONDAY 2024-05-13: Create 12.6 branch
based on one of the latest V8 versions. The auto-roller is closed. Keep in mind that this means we are not integrating with Chromium (much less test coverage). If you happen to work on an important fix, please make sure that the fix is on 12.6 too! See information on merging & patching for the details.
Latest TUESDAY 2024-05-14: Back to normal and API adoption freeze is lifted
Auto-roller is running again and we are back to normal business.

Hi,
We’ve officially branched to be prepared for the upcoming Chromium version 126. The base of the branch is currently rolled into Chromium. It is based on the latest V8 version.
Integration into Chromium is stopped until Chromium has branched too.
V8 branch: refs/branch-heads/12.6
V8 Version: 12.6.228.1
If your CL is not included in 12.6.228.1 (log: https://chromium.googlesource.com/v8/v8/+/refs/branch-heads/12.6) you might consider merging it into the branch refs/branch-heads/12.6. In that case please set the Merge-Request field to: 126 on the bug the CL is fixing. See https://v8.dev/docs/merge-patch for more information on merging.
Thanks,
Lutz
