+## 2.4.1
+
+### Improvements
+* Added a StringMaker for `std::(w)string_view` (#1375, #1376)
+* Added a StringMaker for `std::variant` (#1380)
+  * This one is disabled by default to avoid increased compile-time drag
+* Added detection for cygwin environment without `std::to_string` (#1396, #1397)
+
+### Fixes
+* `UnorderedEqualsMatcher` will no longer accept erroneously accept
+vectors that share suffix, but are not permutation of the desired vector
+* Abort after (`-x N`) can no longer be overshot by nested `REQUIRES` and
+subsequently ignored (#1391, #1392)
