The dominant story today is a continued migration away from arbitrary Ruby execution during install and postinstall, toward structured, JSON-backed metadata. Mike McQuaid landed several connected pieces: PR 22960 lets staged install steps run before a legacy post-install step, so formula and cask behavior can be…

PR 22956 preserves software bill of materials data through the bottle-pouring process instead of regenerating it, and a follow-up, PR 22981, proposes moving that SBOM data into package manifests so it survives reproducibly. Related: PR 22971 adds a warning, rather than a hard…
Second theme: performance. Douglas Eichelberger opened three targeted fixes — PR 22977 cuts linear scans in formula lookups for a roughly twenty percent speedup on install and upgrade, two of the most-run brew commands; PR 22975 parallelizes tap hash generation for up to seventy-seven percent faster tap info; and PR…
