 Inlay hints
 ^^^^^^^^^^^
 
+- Provide hints for:
+    - Lambda return types.
+    - Forwarding functions using the underlying function call.
+- Support for standard LSP 3.17 inlay hints protocol.
+- Designator inlay hints are enabled by default.
+
 Diagnostics
 ^^^^^^^^^^^
+
 - Improved Fix-its of some clang-tidy checks when applied with clangd.
+- Clangd now produces diagnostics for forwarding functions like make_unique.
+- Include cleaner analysis can be disabled with the ``Diagnostics.Includes.IgnoreHeader`` config option.
+- Include cleaner doesn’t diagnose exporting headers.
+- clang-tidy and include cleaner diagnostics have links to their documentation.
 
 Semantic Highlighting
 ^^^^^^^^^^^^^^^^^^^^^
 
-Compile flags
-^^^^^^^^^^^^^
+- Semantic highlighting works for tokens that span multiple lines.
+- Mutable reference parameters in function calls receive ``usedAsMutableReference`` modifier.
 
 Hover
 ^^^^^
 
+- Hover displays desugared types by default now.
+
 Code completion
 ^^^^^^^^^^^^^^^
 
+- Improved ranking/filtering for ObjC method selectors.
+- Support for C++20 concepts and requires expressions.
+
 Signature help
 ^^^^^^^^^^^^^^
 
+- Signature help for function pointers.
+- Provides hints using underlying functions in forwarded calls.
+
 Cross-references
 ^^^^^^^^^^^^^^^^
 
-Objective-C
-^^^^^^^^^^^
+Code Actions
+^^^^^^^^^^^^
+
+- New code action to generate ObjC initializers.
+- New code action to generate move/copy constructors/assignments.
+- Extract to function works for methods in addition to free functions.
+- Related diagnostics are attached to code actions response, if any.
+- Extract variable works in C and ObjC files.
+- Fix to define outline when the parameter has a braced initializer.
 
 Miscellaneous
 ^^^^^^^^^^^^^
 
+- Include fixer supports symbols inside macro arguments.
+- Dependent autos are now deduced when there’s a single instantiation.
+- Support for symbols exported with using declarations in all features.
+- Fixed background-indexing priority for M1 chips.
+- Indexing for standard library symbols.
+- ObjC framework includes are spelled properly during include insertion operations.
