## [2.1.1] - 2021-06-14

### Fixed

- Updating a path that had a map as value with `deep_update_with` returned
  `error` instead of the map value.

## [2.1.0] - 2020-07-02

### Added

- New [`deep_update_with/4`][deep_update_with-4] function

[deep_update_with-4]: https://hexdocs.pm/mapz/mapz.html#deep_update_with-4

## [2.0.0] - 2019-11-27

### Added

- New [`deep_update/3`][deep_update-3] function
- New [`deep_update_with/3`][deep_update_with-3] function

[deep_update-3]: https://hexdocs.pm/mapz/mapz.html#deep_update-3
[deep_update_with-3]: https://hexdocs.pm/mapz/mapz.html#deep_update_with-3

### Changed

- The `{badvalue, P}` exception from `deep_put/3` now returns a path to the bad
  value instead of the value itself to make it coherent with the new
  `deep_update/3` implementation.
- The `{badkey, K}` exception from `deep_get/2` has been changed to
  `{badvalue, P}` to make it coherent with `deep_put/3` and others.

## [1.0.0] - 2019-11-26

### Added

- Clarified documentation for `deep_put/3` regarding possible exceptions.

### Changed

- `deep_remove` now removes the last existing key in the path, ignoring the rest
  to keep it in line with the behavior of `maps:remove/1` which silently returns
  the map if the key doesn't exist.
