 ===========================
+
+Fixes
+-----
+

+
+Features
+--------
+
+* Implemented P0608: sane variant converting constructor.
+* Added `ssize` function.
+* Added `front` and `back` methods in `std::span`.
+* `std::is_unbounded_array` and `std::is_bounded_array` added to type traits.
+* `std::atomic` now includes many new features and specialization including improved Freestanding support.
+* Added `std::midpoint` and `std::lerp` math functions.
+* Added the function `std::is_constant_evaluated`.
+* Erase-like algorithms now return size type.
+* Added `contains` method to container types.
