@dselsam @Armael: this feature may be useful for you.
The doc/changes.md describes many other new features.

at issue #1694
- Users can provide configuration parameters.
- `dunfold_occs` was deleted.

feat(library/tactic): add dsimp_config configuration object for the dsimp tactic family

Now, `dsimp` fails if the goal did not change.
We can use the config object to obtain the previous behavior:
```
dsimp {fail_if_unchaged := ff}
```

feat(library/init/meta/rewrite_tactic): improve rewrite tactic

`rewrite` tactic improvements
- Add support for `auto_param` and `opt_param`
- Order new goals using the same strategies available for `apply`
- Allow user to set configuration object in interactive mode.
@Armael This commit should address the issue you raised about the order
of new goals in the `rewrite` tactic.
See new test tests/lean/run/rw1.lean for examples.

refactor(init/data/nat/bitwise): change definitions to avoid WF
...
The type-correctness of binary_rec_eq (the statement, not the proof) depends on unfolding the embedded well-founded definition of mod. This definition avoids it by using two simpler functions bodd and div2 that reduce well in the kernel.
