It fixes how the tool handles obsolete metadata during upgrades — specifically, old "no autobump" markers and removed dependencies recorded by earlier installations. Before this, a dependency that no longer exists in a formula's current definition could still block someone from…
That connects directly to PR 23960 from Harald Nordgren, a follow-up to earlier work in PR 23945. It refines how `brew info` flags missing dependencies. The fix narrows down false red marks — a required dependency now only avoids the warning if the formula is outdated and that dependency wasn't part of the original…
Rounding out the reliability push, PR 23957 restricts requiring Xcode 27 to macOS 27 specifically, avoiding situations where Homebrew recommends a beta Xcode release on macOS Tahoe. Small fix, but it prevents developers from being pushed toward unstable tooling based on a version mismatch.
