+- amend: add -U/--current-user option
+- evolve: add a --tool option
+- evolve: add a --confirm option
+- mark "commit -o", "graft -o" and "graft -O" as deprecated since they are
+  unlikely to eventually make it into core.
+- push obsmarkers and phases in the same transaction than changesets
+  (when using hg >= 3.1 and bundle2-exp is enabled)
+- hide message about the obsolescence marker exchange behind a
+  `experimental.verbose-obsolescence-exchange` variable (default to False).
