Every guide, comparison and detector run we have published under browser-engine.
Chrome 155 reached the stable channel on 2026-09-23 and the AntiBrow kernel now ships a build of it. The last two release notes were about when to move profiles. This one is about how: one throwaway profile first, a short checklist, then the rest in batches.
Chrome 154 reached the stable channel on 2026-09-09 and the AntiBrow kernel now ships a build of it. The last release note was about not jumping too early. This one is about the other end: how long a profile can sit on an old major before the version itself becomes the odd thing about it.
