[5.0.1]: https://github.com/thoughtbot/bourbon/compare/v5.0.0...v5.0.1

## [5.0.0] - 2018-01-05

Bourbon 5.0.0 is a major release with lots of changes and removals, which are
documented below in each of the alpha and beta releases. There are no changes
between v5.0.0-beta.8 and v5.0.0. For information on how to upgrade from v4 to
v5, read our [migrating guide][migrating-guide].

[5.0.0]: https://github.com/thoughtbot/bourbon/compare/v5.0.0.beta.8...v5.0.0
[migrating-guide]: https://www.bourbon.io/docs/migrating-from-v4-to-v5/

## [5.0.0-beta.8] - 2017-06-26

### Added

- A `style` property has been added to our `package.json`, which makes for easy
  importing when using npm-sass, sass-module-importer and others.

### Changed

- The `triangle` mixin no longer has default argument values. The order of the
  arguments also changed: `$width` and `$height` now come before `$color`.

### Fixed

- The `bourbon update` CLI command now works when Bourbon is installed using a
  custom path.
- Fixed an issue that would cause Bourbon to not be found within Rails apps.

[5.0.0-beta.8]: https://github.com/thoughtbot/bourbon/compare/v5.0.0.beta.7...v5.0.0.beta.8

## [5.0.0-beta.7] - 2016-11-03

### Added

- Added `white-space: nowrap;` to the `hide-visually` mixin so that content
  renders on one line and is correctly pronounced by screen readers. You can
  read more about this in Jesse Beach’s article “[Beware smushed off-screen
    accessible text][smushed-text-article].”

### Changed

- Removed the default values from the `$position` and `$coordinates` arguments
  for the `position` mixin.
- Updated `contrast-switch` to calculate contrast based on the WCAG 2.0
  specification. Please note that it is an approximation and we cannot guarantee
  full compliance, though all of our manual testing passed.
- Renamed the `$coordinates` argument in the `position` mixin
  to `$box-edge-values`.
- Updated `$font-stack-system` to include Avenir Next, Avenir, Lucida
  Grande, Helvetica, Noto, Franklin Gothic Medium, Century Gothic, and
  Liberation Sans. This follows [system-fonts] by Adam Morse.
- The `word-break` property was removed from the `word-wrap` mixin and
  is no longer output.
- Renamed the `word-wrap` mixin to `overflow-wrap` to align with the
  name change in the [CSS spec].

[5.0.0-beta.7]: https://github.com/thoughtbot/bourbon/compare/v5.0.0.beta.6...v5.0.0.beta.7

## [5.0.0-beta.6] - 2016-06-06

### Added

- Added a `value-prefixer` mixin for generating vendor prefixes on values.

[5.0.0-beta.6]: https://github.com/thoughtbot/bourbon/compare/v5.0.0.beta.5...v5.0.0.beta.6

## [5.0.0-beta.5] - 2016-03-23

### Fixed

- Fixed a Sass load path issue that would intermittently break the importing of
  Bourbon in Rails apps.

### Changed

- Swapped the order of the `$file-formats` and `$asset-pipeline` arguments in
  the `font-face` mixin, so that `$asset-pipeline` is last (because it has a
  default and is likely used the least).

[5.0.0-beta.5]: https://github.com/thoughtbot/bourbon/compare/v5.0.0.beta.4...v5.0.0.beta.5

## [5.0.0-beta.4] - 2016-03-11

### Fixed

- We accidentally published `5.0.0.beta.3` as a stable release on npm, rather
  than a prerelease. We’ve unpublished that to go back to `4.2.6` on the stable
  channel.

[5.0.0-beta.4]: https://github.com/thoughtbot/bourbon/compare/v5.0.0.beta.3...v5.0.0.beta.4

## [5.0.0-beta.3] - 2016-03-04

[5.0.0-beta.3]: https://github.com/thoughtbot/bourbon/compare/v5.0.0.beta.2...v5.0.0.beta.3

## [5.0.0-beta.2] - 2016-03-03

### Added

- Added global settings for the `contrast-switch` mixin:
  `contrast-switch-dark-color` & `contrast-switch-light-color`.
- Added the `triangle` mixin back, but note that it’s been refactored and the
  arguments have changed. See [43e5a90].

### Changed

- Switched argument names in `contrast-switch`; `$dark-color` is now
  `$light-color` and `$light-color` is now `$dark-color`.
- The `is-light` function is now private.

### Removed

- Dropped support for Ruby on Rails versions older than 4.2.
- Dropped support for LibSass versions older than 3.3.

[5.0.0-beta.2]: https://github.com/thoughtbot/bourbon/compare/v5.0.0.beta.1...v5.0.0.beta.2
[43e5a90]: https://github.com/thoughtbot/bourbon/commit/43e5a90e7e624d2977731030ccdb36b3c2e460d9

## [5.0.0-beta.1] - 2016-02-09

### Added

- Added a `contrast-switch` function that switches between two colors based on the
  lightness of a another color. Great for building button styles.
- Added an `$all-text-inputs-invalid` variable to target the `:invalid`
  pseudo-class on all text-based inputs.
- The `ellipsis` mixin now takes a `$display` argument.
- Added a font stack for system fonts: `$font-stack-system`.
- Added a `hide-visually` mixin that hides an element visually while still
  allowing the content to be accessible to assistive technology,
  e.g. screen readers.
- The `font-face` mixin now allows additional CSS properties to be included in
  its block, which will output as part of the `@font-face` declaration.
  See [2356719].

### Changed

- The global default for the `modular-scale` ratio is now set to
  `$major-third` (`1.25`), instead of `$perfect-fourth` (`1.333`).
- All font stack variables are now prefixed with `$font-stack-`,
  e.g. `$font-stack-helvetica`.
- Global settings are now set via a `$bourbon` map, instead of variables.
  See [4e43c2d].
- The `clearfix` mixin now uses `block` display, instead of `table`.

### Removed

- The `$weight` and `$style` arguments in the `font-face` mixin have been
  removed. Instead, you can now include these—along with other CSS
  properties—within the mixin block and they’ll be output as part of the
  `@font-face` declaration.

## [5.0.0.alpha.0] - 2015-08-21

### Added

- Added a `$global-font-file-formats` setting to globally set the file formats
  for the `font-face` mixin. The default is `("ttf", "woff2", "woff")`.
- Add `$consolas`, `$courier-new` and `$monaco` variables (these replace the
  removed `$monospace` variable).

### Changed

- Removed the type selectors in `$all-text-inputs` and `$all-buttons` to
  reduce specificity.
- Font stacks have been modernized. See [3cf106a].
- The `strip-units` function is now `strip-unit`.
