Homebrew 7.0.0 ships a built-in vulnerability scanner and drops Intel Macs to Tier 3
Homebrew 7.0.0 landed on 13 September 2026 with `brew vulns`, a command that checks installed formulae against a new advisory database recording vulnerabilities by formula version. Intel Mac support moves to Tier 3 with no new bottles after September 2027, macOS Sonoma 14 also drops to Tier 3, macOS 10.15 and earlier are dropped outright, and third-party `post_install` and cask flight blocks are deprecated with removal set for 11 December 2027. On Linux, Landlock replaces Bubblewrap so sandboxing no longer needs elevated permissions, and downloads now run concurrently.
