Today I’d like to announce Homebrew 2.0.0. The most significant changes since 1.9.0 are official support for Linux and Windows 10 (with Windows Subsystem for Linux), brew cleanup running automatically, no more options in Homebrew/homebrew-core, and removal of support for OS X Mountain Lion (10.8) and older.

Major changes and deprecations since 1.9.0:

  • Homebrew officially supports Linux and Windows 10 with Windows Subsystem for Linux (WSL). “Homebrew on Linux” is called “Linuxbrew”. You can install it in your home directory, so it does not require sudo, and use it to install software that your host distribution’s package manager does not provide. Linuxbrew uses its own repository for formulae: Linuxbrew/homebrew-core
  • brew cleanup is run periodically (every 30 days) and triggers for individual formula cleanup on reinstall, install or upgrade. You can opt-out of this behaviour by setting the HOMEBREW_NO_INSTALL_CLEANUP variable. This addresses a long-standing complaint where users were surprised by how much disk space Homebrew used if they did not run brew cleanup.
  • Homebrew does not run on OS X Mountain Lion (10.8) and below. For 10.4 - 10.6 support, see Tigerbrew. This has allowed us to remove large amounts of legacy code.
  • Homebrew does not migrate old, pre-1.0.0 installations from the Homebrew/legacy-homebrew (formerly Homebrew/homebrew repository. This has allowed us to delete legacy code that dealt with migrations from old versions.
  • Homebrew does not have any formulae with options in Homebrew/homebrew-core. Options will still be supported and encouraged by third-party taps. This change allows us to better focus on delivering binary packages rather than options. Formulae with options had to be built from source, could not be tested on our CI system and provided a disproportionate support burden on our volunteer maintainers.

Other changes since 1.9.0 I’d like to highlight are the following:

Also, if you’ve not tuned in since 1.0.0, here are the major changes since then:


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