 - Fixed a crash when trying to transform a dependent address space type. Fixes #GH101685.
 - Fixed a crash when diagnosing format strings and encountering an empty
   delimited escape sequence (e.g., ``"\o{}"``). #GH102218
+- The warning emitted for an unsupported register variable type now points to
+  the unsupported type instead of the ``register`` keyword (#GH109776).
