No platform changelog lists this item.

Validation

Not QA-tested (QA/No).

No QA pass labels.

QA labels are Brave’s own validation records per OS. They are not independent verification by this tracker.

Target

1.81.x - Release

For closed issues Brave sets the milestone to the earliest version line it believes the change landed in, and renames milestones as branches move from Nightly to Beta to Release. This tracker shows it but relies on build ancestry and release notes for availability.

Build presence

Whether a merged pull request in this group is an ancestor of the brave-core tag of each platform’s current build (from versions.brave.com). Code presence is not the same as a feature being exposed on that platform.
