2.3.0

29 May 2020

Today I’d like to announce Homebrew 2.3.0. The most significant changes since 2.2.0 are GitHub Actions CI usage, fetching resources before installation, Docker image improvements and the deprecation of brew install from URLs.

Major changes and deprecations since 2.2.0:

• brew tap-pin and brew tap-unpin have been removed along with the deprecation of some Homebrew and Formula methods.
• brew install from a URL has been deprecated to improve the security of brew install.
• brew install, brew upgrade and brew reinstall now fetch all resources before beginning installation or locking dependencies.
• The Homebrew/brew Docker image is now built for Ubuntu 16.04 and 20.04 and includes latest for the latest stable release and master for the master branch.
• Homebrew formulae can be deprecated or disabled to provide an easier transition than deletion (the previous method).
• Homebrew/homebrew-core has been entirely migrated to GitHub Actions and Homebrew’s Jenkins has shut down entirely.

Other changes since 2.2.0 I’d like to highlight are the following:

• brew style and brew readall are run on macOS and Linux for Homebrew/brew and Homebrew/homebrew-core to make retaining Linux compatibility easier and ease the eventual merging of homebrew-core and linuxbrew-core taps.
• Homebrew searches the entire PATH to find a compatible ruby.
• brew cask info shows cask analytics data.
• brew doctor shows deleted formulae.
• brew uninstall notes all etc files will stay around.
• brew test runs pkill without exceptions to avoid manual cleanup in test do blocks.
• pkg-config correctly sets the SDKROOT to find more macOS-provided software.
• Formulae can use the pkgetc method to install into etc/#{formula_name}.
• Formulae can use the free_port test helper.
• All Homebrew curl requests retry 2 times by default.
• Formulae patch blocks can change directories to apply their patch.
• brew tap defaults to full clones. The existing shallow clone default would cause slower git fetches over time.
• HOMEBREW_BREW_GIT_REMOTE and HOMEBREW_CORE_GIT_REMOTE environment variables allow you to use custom Git mirrors to speed up brew update and brew tap.

Finally:

• I (Mike McQuaid) stood down from the Homebrew PLC and was reelected Project Leader. Sean Molenaar joined the PLC. (@MikeMcQuaid)
• Homebrew accepts donations through GitHub Sponsors and still accepts donations through Patreon. If you can afford it, please consider donating. If you’d rather not use GitHub Sponsors or Patreon (our preferred donation methods), check out the other ways to donate in our README.

Thanks to all our hard-working maintainers, contributors, sponsors and supporters for getting us this far. Enjoy using Homebrew!
