 ### Improvements to clang-doc

+### Improvements to clang-include-cleaner
+
+- Added Objective-C support to the include analysis. References made through
+  interfaces, protocols, categories, compatible aliases, instance variables,
+  properties, message sends, `@selector` expressions, literals and boxed
+  expressions, and toll-free bridged casts are now attributed to the headers
+  that declare them, and forward declarations of interfaces and protocols no
+  longer satisfy a use that needs the definition. This also applies to clangd
