+author: oleavr
+version: 16.6.4
+categories: [release]

+
+This release brings important fixes and improvements:
+
+- **objc**: Handle extended block type encoding (thanks to [@mrmacete][]).
+- **module**: Reverted the previous optimization of `NativeModule` lifecycle,
+  as the underlying performance issue in our GLib patch has been addressed.
+- **darwin**: Fixed an issue where `Module.load()` could fail when provided
+  with an alias. On macOS >= 13, we now use `_dyld_get_dlopen_image_header()`
+  to resolve modules by address.
+- **linux**: Revived support for ARM BE8, restoring compatibility with
+  big-endian ARM systems.
