This is Homebrew, your developer briefing for September 2nd, 2026.
The dominant theme today is defense in depth: locking down network access by default, and fixing tools that made incorrect assumptions about their inputs.
Michael Cho's team continued a multi-part rollout of deny network access across formula creator modes. Starting with cmake, meson, perl, and autotools in PR 23730, then go and rust in 23734, and finally cabal and zig in 23739. The pattern here matters: newly created formulae now default to no network access during…
Correctness fixes showed up in tooling that parses untrusted or ambiguous input. Patrick Linnane's PR 23736 fixed how the vulnerability matcher interprets version ranges, distinguishing an explicit fixed event from a mere upper bound. That one bug was inflating fix-version claims across nineteen advisory records.…
Second theme: Mike McQuaid is preparing infrastructure for a major or minor release. PR 23729 kicks off the deprecation cycle, while 23732 and 23733 retire the legacy sync workflow and slim the old master branch down to a bare bootstrap, with a hard cutoff warning for March 2027. Expect more deprecation and cleanup…
Smaller but notable: PR 23723…
