+- Type hints
+    * Improved heuristics for showing sugared vs. desguared types
+    * Some hints which provide no information (e.g. ``<dependent-type>``) are now omitted
+- Parameter hints
+    * Parameter hints are now shown for calls through function pointers
+    * Parameter hints are now shown for calls to a class's ``operator()``
+    * No longer show bogus parameter hints for some builtins like ``__builtin_dump_struct``
 
 Compile flags
 ^^^^^^^^^^^^^
 
+- System include extractor (``--query-driver``) improvements
+    * The directory containing builtin headers is now excluded from extracted system includes
+    * Various flags which can affect the system includes (``--target``, ``--stdlib``, ``-specs``) are now forwarded to the driver
+    * Fixed a bug where clangd would sometimes try to call a driver that didn't have obj-c support with ``-x objective-c++-header``
+    * The driver path is now dot-normalized before being compared to the ``--query-driver`` pattern
+    * ``--query-driver`` is now supported by ``clangd-indexer``
+- Fixed a regression in clangd 17 where response files would not be expanded
