+### Added

+- **Linux ARM64 wheel** - Build and publish a manylinux `aarch64`
+  (`aarch64-unknown-linux-gnu`) wheel so `pip install duroxide` works in
+  Linux ARM64 containers without compiling from source.
+- **Linux ARM64 CI smoke** - Run local wheel and post-publish registry smoke
+  on `ubuntu-24.04-arm`.
