 ## Release Notes
 
-### v1.5.1 (WIP)
-
+### [v1.5.2](https://github.com/gulrak/filesystem/releases/tag/v1.5.2)
+
+* Enhancement [#104](https://github.com/gulrak/filesystem/issues/104),
+  on POSIX backend: optimized reuse of status information and reduced
+  `directory_entry` creation leads to about 20%-25% in tests with
+  `recursive_directory_iterator` over a larger directory tree.
+* Pull request [#103](https://github.com/gulrak/filesystem/pull/103), `wchar_t`
+  was not in the list of supported char types on non-Windows backends.
+* Pull request [#102](https://github.com/gulrak/filesystem/pull/102), improved
+  `string_view` support makes use of `<string_view>` or `<experiemental/string_view>`
+  when available, and allows use of custom `basic_string_view` implementation
+  when defining `GHC_HAS_CUSTOM_STRING_VIEW` and importing the string view
+  into the `ghc::filesystem` namespace before including filesystem header.
 * Pull request [#101](https://github.com/gulrak/filesystem/pull/101), fix for
   [#100](https://github.com/gulrak/filesystem/issues/100), append and concat
   type of operations on path called redundant conversions.
