+  * Mercurial installation built with the Rust parts will now use the
+    "persistent nodemap" feature by default. This feature was introduced in
+    Mercurial 5.4 (May 2020). However Mercurial instalation built without the
+    fast Rust implementation will refuse to interract with them by default.
+    This restriction can be lifted through configuration.
