Homebrew 7.0.0, dated September 13, adds built-in vulnerability checks and installation protections, drops macOS 10.15 support, and moves Intel Macs to Tier 3. Its migration tables also flag retired CI images and action references, so an automatic update can affect more than the local command line. Review affected machines and CI references against the release notes before updating; the notes contain inconsistent timing for Intel support, so verify the applicable support table rather than assuming a deadline.
