MikeMcQuaidToday I’d like to announce Homebrew 3.0.0. The most significant changes since 2.7.0 are official Apple Silicon support and a new bottle format in formulae.
Major changes and deprecations since 2.7.0:
- Apple Silicon is now officially supported for installations in
/opt/homebrew. formulae.brew.sh formula pages indicate for which platforms bottles (binary packages) are provided and therefore whether they are supported by Homebrew. Homebrew doesn’t (yet) provide bottles for all packages on Apple Silicon that we do on Intel x86_64 but we welcome your help in doing so. Rosetta 2 on Apple Silicon still provides support for Intel x86_64 in/usr/local. brew bottleandbottle doblocks use a new syntax format (one:cellarper platform).brew style --fixwill autocorrect formulae to this new format. This will allow more bottles to be relocatable.- The new
HOMEBREW_BOOTSNAPenvironment variable allows the use of the Bootsnap gem to speed up repeatedbrewcalls. This does not work (yet) on Apple Silicon or using Homebrew’s portable Ruby. - Various methods have been deprecated, disabled and removed
- Bash, fish and zsh completions are generated automatically from the
CLI::ParserDSL. This will ensure they are kept up-to-date. brew updatebetter handles upstream branch renames (e.g. frommastertomain)brew completionsis a new command to opt-in to completions provided by third-party taps
Other changes since 2.7.0 I’d like to highlight are the following:
- Command usage text is automatically generated (so will be kept-up-to-date)
brew auditreads more formula data from tapsbrew untapof an official tap you don’t use (e.g. Homebrew/homebrew-cask) will ensure it’s no longer automatically retappedbrew casksis a new command implemented in Bash to speedily output all casks available to install (likebrew formulae)brew info --cask --json=v2includes whether a cask is outdated and the currently installed versions- Fixed a bug where
brew updatecould be run every time brew --prefix --installedis a new flag tobrew --prefixthat will fail if the requested formula is not installed- We now use an unversioned SDK path on Big Sur to avoid breakage on minor SDK version changes
Finally:
- Discourse was made read-only on January 1st 2021 in favour of GitHub Discussions.
- 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. Particular thanks on Homebrew 3.0.0 go to MacStadium and Apple for providing us with a lot of Apple Silicon hardware and Cassidy from Apple for helping us in many ways with this migration. Enjoy using Homebrew!
