 # Changelog
 
+## Unreleased
+
+- Added support for bitstyles `v5.0.0`. You can continue using bitstyles_phoenix with a lower bitstyles version, or migrate your codebase to bitstyles `v5.0.0`.
+
+### How to migrate to bitstyles `v5.0.0`
+
+Follow the [bitstyles changelog](https://github.com/bitcrowd/bitstyles/blob/main/CHANGELOG.md#500---2023-01-03) for versions 5.0.0 and 5.0.0-alpha-1. Even if you're using the `BitstylesPhoenix.Helper.Classnames.classnames/1` helper to apply bitstyles classes in your own codebase, you will still need to migrate some of them yourself. For example, the class `u-gap-m` could not have been migrated via the helper because it exists in both bitstyles versions with different meanings (`u-gap-m` and `u-gap-l` in bitstyles 4.3.0 are equivalent to `u-gap-l` and `u-gap-xl` in bitstyles `v5.0.0`).
+
+The `variant` attribute of the `Button` component is deprecated in bitstyles `v5.0.0`. Use the attributes `shape` and `color` instead.
