Since Homebrew 1.0.0 most Homebrew users (those who haven't run a `dev-cmd` or set `HOMEBREW_DEVELOPER=1` which is ~99.9% based on analytics data) require tags on the [Homebrew/brew repository](https://github.com/homebrew/brew) in order to receive new versions of Homebrew. There are a few steps in making a new Homebrew release:
1. Check if there is anything pressing that needs to be fixed or merged before the next release in:
Also delete any command argument definitions that pass `replacement: ...`.
2. Write up a release notes blog post for <https://brew.sh> (e.g. [brew.sh#319](https://github.com/Homebrew/brew.sh/pull/319)). This should use the output from `brew release [--major|--minor]` as input but have the wording adjusted to be more human readable and explain not just what has changed but why.
3. When the release has shipped and the blog post has been merged, tweet the blog post as the [@MacHomebrew Twitter account](https://twitter.com/MacHomebrew) or tweet it yourself and retweet it with the @MacHomebrew Twitter account (credentials are in 1Password).
Please do not manually create a release based on older commits on the `master` branch. It's very hard to judge whether these have been sufficiently tested by users or if they will cause negative side effects with the current state of Homebrew/homebrew-core. If a new branch is needed ASAP but there are things on `master` that cannot be released yet (e.g. new deprecations and you want to make a patch release) then revert the relevant PRs, follow the process above and then revert the reverted PRs to reapply them on `master`.
