- Fixed a bug where the deprecated `DidYouMean::Formatter` has been removed unexpectedly ([#103](https://github.com/ruby/did_you_mean/issues/103), [<tt>4b5ba32</tt>](https://github.com/ruby/did_you_mean/commit/4b5ba3215975df1dd8e9c7eacffcf02abfffa92e))

- New Formatter API: This provides a clean way to customize DidYouMean’s formatter without overriding the default formatter. Please refer to [the built-in verbose formatter](https://github.com/ruby/did_you_mean/blob/671cdff/lib/did_you_mean/verbose.rb) for how to use it

## [v1.1.0](https://github.com/ruby/did_you_mean/tree/v1.1.0)
_<sup>released at 2016-12-19 23:19:06 UTC</sup>_
The version `1.1.0` only has support for Ruby 2.4.0 and later. Also, all patch releases under `1.1.*` will only be compatible with Ruby 2.4.0 and later as well. Versions under `1.0.*` will still be maintained until Ruby 2.3 is deprecated. Any other versions below `1.0` will no longer be maintained.
#### New Features

# => NameError: no member 'fooo' in struct
# Did you mean? foo
# foo=
```
- Added a public interface for the gem's spell checker:
```ruby
DidYouMean::SpellChecker.new(dictionary: ['email', 'fail', 'eval']).correct('meail')
# => ['email']
```
- Methods defined on `nil` by default are no longer suggested. Note that methods, defined after the gem is loaded, will still be suggested (e.g. ActiveSupport).
#### Bug Fixes
- Fixed a bug where private method names were added to the dictionary when an argument was passed in to a public method. Use the `NoMethodError#private_call?` method instead ([<tt>0a1b761</tt>](https://github.com/ruby/did_you_mean/commit/0a1b7612252055e583a373b473932f789381ca0f))

## [v1.0.2](https://github.com/ruby/did_you_mean/tree/v1.0.2)

- `require 'did_you_mean/extra_features'` is now deprecated in favor of `require 'did_you_mean/experimental'`
#### Internal Changes

This is a slower implementation but close to the model explained in [this talk](https://speakerdeck.com/yuki24/saving-people-from-typos), more reusable and possibly makes it easier to expose the class as a public interface.
## [v1.0.1](https://github.com/ruby/did_you_mean/tree/v1.0.1)

## [v1.0.0.beta3](https://github.com/ruby/did_you_mean/tree/v1.0.0.beta3)

- Now it forces everyone to upgrade the gem when they upgrade Ruby to a new version. This avoids introducing a bug like [#14](https://github.com/ruby/did_you_mean/issues/14 "Compatibility with `letter\_opener` gem").
