+
+Today, I'd like to announce Homebrew 4.5.0.
+The most significant changes since 4.4.0 are major improvements to `brew bundle`/`services`, preliminary Linux support for casks, official Support Tiers, Tier 2 ARM64 Linux support, Ruby 3.4 and several deprecations.
+
+Major changes and deprecations since 4.4.0:
+
+#### `brew bundle` and `brew services`
+
+- [The documentation for Homebrew Bundle, `brew bundle` and `Brewfile`](https://docs.brew.sh/Brew-Bundle-and-Brewfile)
+  has been [hugely improved](https://github.com/Homebrew/brew/pull/19802).
+  It also documents the many new `brew bundle` features and changes in this release.
+- [`brew bundle`](https://github.com/Homebrew/brew/pull/19487)
+  and
+  [`brew services`](https://github.com/Homebrew/brew/pull/19385)
+  are built-in commands instead of being provided by an external tap.
+- [`brew bundle (exec|env|sh)` no longer filter the user's environment](https://github.com/Homebrew/brew/pull/19575) (like other `brew` commands do)
+- [`brew services` supports passing multiple formulae](https://github.com/Homebrew/brew/pull/19565)
+- [`Brewfile`s have a `version_file:` DSL that allows `brew bundle` to write to e.g. a `.ruby-version` file based on the installed version](https://github.com/Homebrew/brew/pull/19579)
+- `brew bundle` no longer includes `${HOMEBREW_PREFIX}/bin` in the `$PATH` by default.
+  You can do this in your `Brewfile` with `ENV["PATH"] = "#{HOMEBREW_PREFIX}/bin:#{ENV["PATH"]}"`.
+
+#### Linux casks
+
+- Some Homebrew casks are supported on Linux.
+  Right now these are mostly
+  [fonts](https://github.com/Homebrew/brew/pull/18874)
+  and those with
+  [Linux binaries](https://github.com/Homebrew/brew/pull/19121).
+  Some casks will never be available on Linux, such as those for macOS-specific software.
+  [The Homebrew Linux fonts cask tap has been deprecated as a result](https://github.com/Homebrew/brew/pull/19834).
+- [`brew bump-cask-pr` allows bumping multi-platform casks on Linux](https://github.com/Homebrew/brew/pull/19510)
+
+#### Support Tiers
+
+- [Homebrew has three documented Support Tiers plus Unsupported](https://docs.brew.sh/Support-Tiers).
+  Tier 1, previously called "supported", is where you'll get bottles/binary packages and we have CI coverage.
+- [`brew doctor` links to Support Tiers](https://github.com/Homebrew/brew/pull/19657)
+- [`brew doctor` checks for OpenCore Legacy Patcher](https://github.com/Homebrew/brew/pull/18762)
+- [Clarify that the OpenCore Legacy Patcher is Tier 2 or 3](https://github.com/Homebrew/brew/pull/19751)
+
+#### ARM64 Linux
+
+- [Homebrew provides a Portable Ruby for ARM64 Linux](https://github.com/Homebrew/brew/pull/19224).
+  This is the first step towards hopefully being able to provide Tier 1 support for ARM64 Linux in the future.
+- [Homebrew refers to ARM64 Linux, not AArch64 Linux](https://github.com/Homebrew/brew/pull/19188) (for consistency with macOS)
+- [Homebrew publishes some ARM64 Docker images](https://github.com/Homebrew/brew/pull/19275)
+
+#### Ruby
+
+- [Homebrew provides Portable Ruby 3.4.3](https://github.com/Homebrew/brew/pull/19779).
+  It also requires Ruby >=3.4 to run.
+- [Homebrew has enabled Bootsnap by default](https://github.com/Homebrew/brew/pull/19658). This should make repeated invocations of `brew` much faster.
+
+#### Deprecations
+
+- [Homebrew 4.5's various deprecations/disables/removals](https://github.com/Homebrew/brew/pull/19801)
+- [The Ubuntu 18 Docker image has been removed](https://github.com/Homebrew/brew/pull/19190)
+
+Other changes since 4.4.0 I'd like to highlight are the following:
+
+- [`brew install --ask` and `HOMEBREW_ASK` allow viewing the packages, dependencies and sizes in a prompt before installation](https://github.com/Homebrew/brew/pull/19254)
+- [`brew install --skip-link` allows installation without running `brew link`](https://github.com/Homebrew/brew/pull/19136)
+- [`brew update-if-needed` provides a much faster possible replacement for `brew update` that does nothing if no auto-update is required](https://github.com/Homebrew/brew/pull/19626)
+- [`brew install --as-dependency` allows installation of formulae as dependencies rather than "on request"](https://github.com/Homebrew/brew/pull/19570)
+- [`brew` allows being run by `root` in `podman` containers](https://github.com/Homebrew/brew/pull/18574)
+- [`HOMEBREW_TEMP` defaults to `/var/tmp` on Linux, assuming it exists, is readable and is writable](https://github.com/Homebrew/brew/pull/19824)
+- [`brew install --cask` produces fewer GitHub Actions warnings](https://github.com/Homebrew/brew/pull/19009)
+- [Homebrew supports GCC 15](https://github.com/Homebrew/brew/pull/19811)
+- [`brew pyenv-sync` creates major version symlinks to fix `pyenv` support](https://github.com/Homebrew/brew/pull/18978)
+- [The Homebrew macOS `.pkg` installer will upgrade existing installations](https://github.com/Homebrew/brew/pull/19406)
+- [`HOMEBREW_UPGRADE_GREEDY_CASKS` allows specifying a list of casks that should always be upgraded with `--greedy`](https://github.com/Homebrew/brew/pull/19375)
+- Formulae can include
+  [PowerShell (`pwsh`)](https://github.com/Homebrew/brew/pull/19407)
+  or
+  [`clap`](https://github.com/Homebrew/brew/pull/18945)
+  completions.
+- [`@@HOMEBREW_PREFIX@@` can be replaced with the value of `HOMEBREW_PREFIX` in external patches](https://github.com/Homebrew/brew/pull/18613)
+- [`brew alias` and `brew unalias` commands are part of Homebrew/brew rather than an external tap](https://github.com/Homebrew/brew/pull/19258)
+- [`brew edit` and `brew bundle edit` look for VSCode variants, e.g. Cursor](https://github.com/Homebrew/brew/pull/19545)
+- [`brew bump*` can bump synced formulae together](https://github.com/Homebrew/brew/pull/19798)
+- [`brew *env-sync` has a `HOMEBREW_ENV_SYNC_STRICT` mode for stricter version handling](https://github.com/Homebrew/brew/pull/19577)
+- In formulae and casks,
+  [`deprecate!`/`disable!` support specifying replacement software](https://github.com/Homebrew/brew/pull/18733)
+  and
+  [can specify replacement type](https://github.com/Homebrew/brew/pull/19578)
+- [`brew bump-*` only warns, rather than errors, on duplicate PRs for non-official taps](https://github.com/Homebrew/brew/pull/19670)
+- [`brew verify` allows verifying package attributions](https://github.com/Homebrew/brew/pull/19217)
+- [`brew audit` flags `pkg-config` dependencies in core tap](https://github.com/Homebrew/brew/pull/18843).
+  We have fully moved to using `pkgconf` in Homebrew/homebrew-core instead.
+- [Formulae allow using Sequoia's `jq` instead of Homebrew's](https://github.com/Homebrew/brew/pull/18826)
+- [`brew config` prints the current Homebrew/brew branch](https://github.com/Homebrew/brew/pull/18811)
+- [Homebrew's Tabs/`INSTALL_RECEIPT.json` include the `bottle_rebuild` in `runtime_dependencies`](https://github.com/Homebrew/brew/pull/19576)
+- [Homebrew will use macOS's new `lockf` where available](https://github.com/Homebrew/brew/pull/18516)
+- [Homebrew's CI is no longer running `brew tests` on macOS 13](https://github.com/Homebrew/brew/pull/19736).
+  It was too slow and we're dropping macOS 13 support later this year.
+
+Finally:
+
+- [Homebrew has switched to SSH-based Git commit signing](https://brew.sh/2025/02/03/Homebrew-git-signing/)
+- [Homebrew has provided FAQs about their relationship with Workbrew](https://brew.sh/2024/11/19/homebrew-and-workbrew/)
+- [Homebrew accepts donations through GitHub Sponsors](https://github.com/sponsors/Homebrew) and [still accepts donations through Patreon](https://www.patreon.com/homebrew).
+  If you can afford it, please consider donating.
+  If you'd rather not use GitHub Sponsors or Patreon (our preferred donation methods), [check out the other ways to donate in our README](https://github.com/Homebrew/brew/#donations).
+
+Thanks to all our hard-working maintainers, contributors, sponsors and supporters for getting us this far.
