 ## Unreleased
 
-- Support more leniant usernames and group names in FTP servers [#507](https://github.com/PyFilesystem/pyfilesystem2/pull/507). Closes [#506](https://github.com/PyFilesystem/pyfilesystem2/pull/506).
+### Changed
+
+- Support more lenient usernames and group names in FTP servers
+  ([#507](https://github.com/PyFilesystem/pyfilesystem2/pull/507)).
+  Closes [#506](https://github.com/PyFilesystem/pyfilesystem2/issues/506).
+
+### Fixed
+
+- Fixed `MemoryFS.move` and `MemoryFS.movedir` not updating the name of moved
+  resources, causing `MemoryFS.scandir` to use the old name.
+  ([#510](https://github.com/PyFilesystem/pyfilesystem2/pull/510)).
+  Closes [#509](https://github.com/PyFilesystem/pyfilesystem2/issues/509).
