Homebrew: 7.0.0 - faster installations and upgrades, stronger sandboxing, a native macOS app, built-in vulnerability checks and an advisory database, the end of macOS 10.15 support and Intel Macs moving to Tier 3.

Homebrew installations will become materially faster and more secure by default.

Homebrew has released version 7.0.0, introducing significant improvements including faster installations and upgrades through enhanced concurrency and reused data. The package manager now features stronger sandboxing to limit arbitrary Ruby execution and protect user files, alongside built-in vulnerability checks and an advisory database for enhanced security. A native macOS app and improved command-line diagnostics aim to streamline user experience. However, this release also marks the end of support for macOS 10.15 and designates Intel Macs as Tier 3, meaning they will receive fewer prebuilt packages and limited support after September 2027. Homebrew is also migrating its Linux images and modifying its bootstrap process to align with updated practices.

The introduction of enhanced concurrency and caching mechanisms in Homebrew 7.0.0 directly addresses user pain points regarding installation speed. By overlapping package preparation, download, and installation phases, and by reusing parsed API data, Homebrew aims to drastically reduce the time users spend waiting for software to be set up. This performance boost is crucial for developers and users managing complex environments or frequently updating dependencies. Furthermore, the integration of vulnerability checks and an advisory database signals a proactive approach to security, shifting some of the burden from users to the package manager itself.

Homebrew's decision to deprecate support for older macOS versions and Intel Macs indicates a broader industry trend of accelerating the move towards newer hardware and operating systems. While this change might inconvenience users on older systems, it allows Homebrew maintainers to focus resources on modern platforms, enabling features like stronger sandboxing and native applications. The move to Tier 3 for Intel Macs, with support ending in September 2027, compels users to consider hardware upgrades if they wish to continue receiving timely updates and prebuilt packages, aligning with the lifecycle of many software projects.
