Good morning, it’s October 10th, 2026, you’re listening to Homebrew.
The big pattern this week is safer installs and upgrades, with three tightly linked installer fixes plus a security hardening for taps.
First, reliability in the installer. PR 24207 fixes a false lock failure when linking splits off a sibling that’s already locked — the case seen installing Q T with both O S S L versions — by unlinking already-held siblings without relocking, and releasing partial locks on failure. PR 24209 stops a double build from…
Second, tap trust. PR 24198 closes a redirect spoof where any host over S S H could relabel its checkout as an official tap. Renames now only follow Git’s resolved origin on GitHub dot com, never into or out of official trust, and rollbacks after update are stricter. Related, PR 24201 stops hidden folders under the…
Third, clearer signals and speed. PR 24213 makes test-bot report net dependency impact by comparing full runtime dependencies at base and head, so swapping O S S L versions no longer counts shared pieces as new. Open PR 24210 would show versions in install dry-run to match upgrade dry-run. And merged speedups…
What’s next: expect fewer spurious upgrade…
