Good day, and welcome to Homebrew, July 28th, 2026.
The signal today is performance. A cluster of merged pull requests all attack the same target: the cost of running brew itself, before it even does useful work.
Start with startup. PR 23298 removes most of the forked processes brew used to spawn just to read git config and git state, reading files directly in Bash instead. PR 23332 builds on that by preserving locale settings without repeatedly shelling out to list locales. Together, these strip overhead out of every single…
Then there's data loading. PR 23300 tackles the fifteen-megabyte signed API payload that every formula-aware command has to parse. Now a verified sidecar cache lets warm runs skip re-parsing that envelope, while signature verification still happens every time, so speed doesn't come at the cost of trust. PR 23301…
Rounding out the cleanup, PR 23309 strips out several vendored gems, replacing custom URL and JWS handling with Ruby's built-in tools, and deferring heavy runtime dependencies until needed. Less to load, less to maintain, less attack surface.
A second, smaller theme is correctness fixes surfacing from edge cases. PR 23333 fixes a crash in tap info by…
