1.0.0

We've been working hard over the last year to make some major changes to Homebrew that we've been wanting for a long time. There have been some hiccups along the way but we now have a more stable base for using and developing Homebrew in future.

These include:

• Homebrew package management and formulae (package metadata) split into separate repositories
• Homebrew Community site (using Discourse) for discussion
• Homebrew joined the Software Freedom Conservancy
• Homebrew's default repository installation location changed to /usr/local/Homebrew to keep your /usr/local cleaner
• Homebrew/brew updates between release tags
• Homebrew CI and homebrew/core use the OS X sandbox for build-time security
• Homebrew Cask integrated into Homebrew/brew
• Add new brew bump-formula-pr command to create new formula version pull requests
• Add brew --help to brew subcommands
• Homebrew auto-updates when needed
• brew update sped up by only running git fetch if necessary
• Officially support brew bundle (for Brewfiles and import/export) and brew services (for background services management).
• Homebrew/brew passes tests on Linux and has generic backend for porting to other platforms in future
• Provide access to developer commands and brew update workflow automatically
• Use curl for all HTTP access for consistent proxy support
• Use new Ruby Macho library for reading and writing library macOS Mach O file locations.
• Provide vendored, portable Ruby 2 binary for when system Ruby 2 is not available
• HEAD package installations have versions and can be upgraded
• Use Python virtualenvs to better handle Python dependencies

And finally:

• Improves formula not found handling
