-# 0.4.1
-
-Improvements:
-
-- Add Train-Case support
-
-# 0.4.0
-
-Breaking changes:
-
-* Make unicode support optional (off by default). Enable the `unicode` crate
-  feature if you need unicode support.
-* Rename all traits from `SomeCase` to `ToSomeCase`, matching `std`s convention
-  of beginning trait names with a verb (`ToOwned`, `AsRef`, …)
-* Rename `ToMixedCase` to `ToLowerCamelCase`
-* Rename `ToCamelCase` to `ToUpperCamelCase`
-* Add `ToPascalCase` as an alias to `ToUpperCamelCase`

-# **heck** is a case conversion library
-
-!["I specifically requested the opposite of this."](./no_step_on_snek.png)
-
-This library exists to provide case conversion between common cases like
-CamelCase and snake_case. It is intended to be unicode aware, internally
-consistent, and reasonably well performing.
-
-## Definition of a word boundary
-
-Word boundaries are defined as the "unicode words" defined in the
-`unicode_segmentation` library, as well as within those words in this manner:
-
-1. All underscore characters are considered word boundaries.
-2. If an uppercase character is followed by lowercase letters, a word boundary
-is considered to be just prior to that uppercase character.
-3. If multiple uppercase characters are consecutive, they are considered to be
-within a single word, except that the last will be part of the next word if it
-is followed by lowercase characters (see rule 2).
-
-That is, "HelloWorld" is segmented `Hello|World` whereas "XMLHttpRequest" is
-segmented `XML|Http|Request`.
-
-Characters not within words (such as spaces, punctuations, and underscores)
-are not included in the output string except as they are a part of the case
-being converted to. Multiple adjacent word boundaries (such as a series of
-underscores) are folded into one. ("hello__world" in snake case is therefore
-"hello_world", not the exact same string). Leading or trailing word boundary
-indicators are dropped, except insofar as CamelCase capitalizes the first word.
-
-## Cases contained in this library:
-
-1. UpperCamelCase
-2. lowerCamelCase
-3. snake_case
-4. kebab-case
-5. SHOUTY_SNAKE_CASE
-6. Title Case
-7. SHOUTY-KEBAB-CASE
-8. Train-Case
-
-## Contributing
-
-PRs of additional well-established cases welcome.
-
-This library is a little bit opinionated (dropping punctuation, for example).
-If that doesn't fit your use case, I hope there is another crate that does. I
-would prefer **not** to receive PRs to make this behavior more configurable.
-
-Bug reports & fixes always welcome. :-)
-
-## MSRV
-
-The minimum supported Rust version for this crate is 1.32.0. This may change in
-minor or patch releases, but we probably won't ever require a very recent
-version. If you would like to have a stronger guarantee than that, please open
-an issue.
-
-## License
-
-heck is distributed under the terms of both the MIT license and the
-Apache License (Version 2.0).
-
-See LICENSE-APACHE and LICENSE-MIT for details.
