   - There is a new connective `tc_opaque`, which can be used to make definitions
     opaque for type classes, and thus opaque for most tactics of the proof
     mode.
-  - Many missing type class instances for distributing connectives have been
-    defined.
-  - The tactics `iIntros (?)` and `iIntros "!#"` (i.e. `iAlways`) are now
-    implemented using type classes. That way, they are more generic, e.g.
-    `iIntros (?)` also works when the universal quantifier is below a modality,
-    and `iAlways` also works for the plainness modality. A breaking change,
-    however, is that these tactics now no longer work when the universal
-    quantifier or modality is behind a type class opaque definition.
-    Furthermore, this can change the name of anonymous identifiers introduced
-    with the "%" pattern.
-* The generic `fill` operation of the `ectxi_language` construct has been
-  defined in terms of a left fold instead of a right fold. This gives rise to
-  more definitional equalities.

 * Use `Hint Mode` to prevent Coq from making arbitrary guesses in the presence
   of evars, which often led to divergence. There are a few places where type
   annotations are now needed.
