 * Added support for defining derived connectives involving n-ary binders using
   telescopes.
+* The proof mode now more consistently "prettifies" the goal after each tactic.
+  Prettification also simplifies some BI connectives, like conditional

+* Added a `gmultiset` RA.
 * Rename `timelessP` -> `timeless` (projection of the `Timeless` class)
 * The CMRA axiom `cmra_extend` is now stated in `Type`, using `sigT` instead of
   in `Prop` using `exists`. This makes it possible to define the function space
