- 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.
