 ## Bug Fixes
 
+- Fixed `fir::getTypeSizeAndAlignment` returning the wrong allocation size for
+  **packed derived types** (`SEQUENCE` types compiled with `PACK` / LLVM

Flang does not derive packed `RecordType`s from the `SEQUENCE` attribute or a `PACK` option. Among source-language paths, only the AIX lowering of `BIND(C)` types sets `pack(true)`, and that lowering adds explicit padding fields. Textual FIR can also declare a packed `RecordType`.

Could the release note refer to explicitly packed FIR `RecordType`s or the AIX lowering of `BIND(C)` types instead of attributing packing to `SEQUENCE` and `PACK`?
