Today I’d like to announce Homebrew 1.9.0. The most significant changes since 1.8.0 are Linux support, (optional) automatic brew cleanup and providing bottles (binary packages) to more Homebrew users.

Future major changes and deprecations coming in 2.0.0:

Homebrew 2.0.0 will officially support Linux and Windows 10 (with the Windows Subsystem for Linux).

brew cleanup will be run periodically and for trigger individual formula cleanup on reinstall, install or upgrade. You can enable this behaviour now on 1.9.0 by setting the HOMEBREW_INSTALL_CLEANUP variable.

Homebrew 2.0.0 will not be able to create universal binaries (even in taps).

Homebrew 2.0.0 will no longer migrate old installations from the legacy Homebrew/homebrew repository.

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