+ * Added some caching for uncompressed revlog chunks that speed up some operations
+
+== New Experimental Features ==
+
+== Bug Fixes ==
+ * Improve OpenVMS support
+ * byteify-strings: passe sysstr to attr function and wrapper
+ * journal: track bookmark deletion
+ * transaction: actually delete file created during the transaction on rollback

+ * run-tests: detect HGWITHRUSTEXT value
+ * censor: accept censored revision during upgrade
+ * rust-matchers: fix quadratic complexity in `FileMatcher`

+ * rust: add `UncheckedRevision` type
+ * rust: implement the `Graph` trait for all revlogs
+ * rust: make `Revision` a newtype
+ * perf: change the way we approach revlog reading

+
+== Miscellaneous ==
