 autowrap 0.24.0 (unreleased)
 
+
+New STL Container Support (C++17):
+
+- Added `std::unordered_map<K,V>` converter - maps to Python `dict`
+- Added `std::unordered_set<T>` converter - maps to Python `set`
+- Added `std::deque<T>` converter - maps to Python `list`
+- Added `std::list<T>` converter - maps to Python `list`
+- Added `std::optional<T>` converter - maps to Python `T | None`
+- Added `std::string_view` converter - maps to Python `bytes`/`str`
+
+Other Changes:
+
+- Updated default C++ standard from C++11 to C++17 for compilation
+  (required for `std::optional` and `std::string_view` support)
+- Fixed converter architecture to properly handle `None` values for
+  `std::optional<T>` input parameters
 - Support for enums with the same name in different C++ namespaces using
   scoped enum declarations with `wrap-as` annotation for renaming
 - Support for arbitrary key types in `operator[]` (getitem/setitem), not
