 ## Release Notes
 
-### v1.6.0 (wip)
+### [v1.5.10](https://github.com/gulrak/filesystem/releases/tag/v1.5.10)
 
+* Pull request [#136](https://github.com/gulrak/filesystem/pull/136), the Windows
+  implementation used some unnecessary expensive shared pointer for resource
+  management and these where replaced by a dedicated code.
+* Fix for [#132](https://github.com/gulrak/filesystem/issues/132), pull request
+  [#135](https://github.com/gulrak/filesystem/pull/135), `fs::remove_all` now
+  just deletes symbolic links instead of following them.
+* Pull request [#133](https://github.com/gulrak/filesystem/pull/133), fix for
+  `fs::space` where a numerical overflow could happen in a multiplication.
 * Replaced _travis-ci.org_  with GitHub Workflow for the configurations:
   Ubuntu 20.04: GCC 9.3, Ubuntu 18.04: GCC 7.5, GCC 8.4, macOS 10.15: Xcode 12.4,
   Windows 10: Visual Studio 2019
