+### 2023-11-22 — Apple Silicon builds, drop macOS 11 support
+
+Apple Silicon builds are now available, but limited to stable releases, and
+nightly builds on the 1st of each month due to the cost of using M1-based
+runners on GitHub Actions. Apple Silicon builds also require macOS 13 Ventura,
+as that is the oldest macOS version available on M1-based runners.
+
+Additionally, Intel builds minimum required macOS version has been increased
+from macOS 11 Big Sur, to macOS 12 Monterey. This was needed as Homebrew no
+longer supports Big Sur, leading to very lengthy and error prone builds as all
+Homebrew dependencies had to be installed from source.
+
+If dropping support for macOS 11 turns out to be a big issue, it may be possible
+to offer macOS 11 compatible builds on a less frequent schedule similar to what
+we're doing with Apple Silicon.
