Branch cut V8 14.1 on 2025-09-01
Michael Achenbach
Hi,
It is time again. If you have any questions regarding the release, please ping this thread.
FRIDAY 2025-08-29: API adoption freeze starts.
V8 will branch on MONDAY for the upcoming Beta phase for Chrome 141.
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 machenbach@.
MONDAY 2025-09-01: Create 14.1 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 14.1 too! See information on merging & patching for the details.
Latest TUESDAY 2025-09-02: Back to normal and API adoption freeze is lifted
Auto-roller is running again and we are back to normal business.
Michael Achenbach
we have officially branched to be prepared for the upcoming Chrome version 141.
Integration into Chromium is stopped until Chromium has branched too.
V8 branch: branch-heads/14.1
V8 Version: 14.1.146
If your CL is not included in 14.1.146, you might consider merging it into
the branch branch-heads/14.1. In that case please apply the label
Merge-Request-141 to the bug the CL is fixing. See
https://v8.dev/docs/merge-patch for more information on merging.
