+Today, I'd like to announce Homebrew 5.0.0.
+The most significant changes since 4.6.0 are download concurrency by default, official support for Linux ARM64/AArch64, timescales for deprecating macOS Intel and removing macOS Gatekeeper bypass behaviours.
+
+Major changes and deprecations since 4.6.0:
+
+- [`HOMEBREW_DOWNLOAD_CONCURRENCY=auto` is set by default](https://github.com/Homebrew/brew/pull/20975).
+  This enables parallel downloads by default for all users.
+  It can be disabled by setting `HOMEBREW_DOWNLOAD_CONCURRENCY=1`.
+  [Concurrent downloads now have progress reporting](https://github.com/Homebrew/brew/pull/20991).
+  We expect there may be a long-tail of issues, please report them!
+- [Homebrew has promoted Linux ARM64/AArch64 to Tier 1 support.](https://github.com/Homebrew/brew/pull/20974)
+- [Casks without codesigning are deprecated](https://github.com/Homebrew/brew/pull/20388).
+  We will disable all Homebrew/homebrew-cask casks that fail Gatekeeper checks in September 2026.
+- Homebrew now provides official macOS 26 (Tahoe) support.
+  [Homebrew's future macOS support is noted in our Support Tiers document](https://github.com/Homebrew/brew/pull/20497)
+  at <https://docs.brew.sh/Support-Tiers#future-macos-support>.
+  In September (or later) 2026:
+  - Homebrew will not run on macOS Catalina 10.15 and earlier
+  - macOS Intel x86_64 will move to Tier 3, dropping CI support and no additional bottles (binary packages) will be built for Intel.
+  In September (or later) 2027:
+  - Homebrew will not run on macOS Big Sur 11 on Apple Silicon or **at all on Intel x86_64**
+- [`HOMEBREW_USE_INTERNAL_API` allows opt-in to the new, smaller internal Homebrew JSON API](https://github.com/Homebrew/brew/pull/20951).
+  This will become the default behaviour in a later version of Homebrew.
+  Please consider opting-in now and reporting any issues you encounter.
