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. This change allows us to better focus on delivering binary packages rather than options. Options will still be supported and encouraged by third-party taps. Homebrew does not have any formulae with options in Homebrew/homebrew-core.This has allowed us to delete legacy code that dealt with migrations from old versions. Homebrew does not migrate old, pre-1.0.0 installations from the Homebrew/legacy-homebrew (formerly Homebrew/homebrew repository.

This has allowed us to remove large amounts of legacy code. Homebrew does not run on OS X Mountain Lion (10.8) and below.This addresses a long-standing complaint where users were surprised by how much disk space Homebrew used if they did not run brew cleanup. You can opt-out of this behaviour by setting the HOMEBREW_NO_INSTALL_CLEANUP variable.
#Homebrew switch install#

Major changes and deprecations since 1.9.0: 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. Today I’d like to announce Homebrew 2.0.0.
