Hello, it's October 31st, 2026, and here's what's happening in Homebrew.
The big signal this week is hardening how Homebrew resolves names and specs, closing paths where a crafted name or install receipt could trigger unexpected code.
First, tighter trust boundaries. Two changes limit cask lookups to token-only paths, covering cache cleanup in PR 24394 and search and install in PR 24396, so a file name shaped like a source or path is no longer loaded as one. That pairs with PR 24407, which restricts install receipt specs to stable and head,…
Second, cleanup that actually respects dry run, plus clearer test feedback. PR 24406 adds the missing dry-run guard to metadata helpers, so a dry-run cleanup of a specific formula or cask no longer deletes system files or prunes linkage cache entries. Separately, PR 24404 keeps the requirement for up-to-date test…
Finally, release and automation foundations. PR 24403 shifts bottle uploads to go through draft releases to support immutable releases on GitHub, which matters for release reliability going forward. And PR 24409 fixes the M C P server to default missing arguments to empty and flag failed brew commands as errors, so…
What's next: expect…
