#145: owo-colors/owo-colors#145

[4.2.1] - 2025-05-15

Fixed

• Fixed a couple of bugs while rendering custom colors (#144). Thanks https://github.com/MiguelValentine for your first contribution!

#144: owo-colors/owo-colors#144

[4.2.0] - 2025-02-22

Added

• Style::prefix_formatter and Style::suffix_formatter return Display formatters for the prefix and the suffix of a style, respectively.
• All the *Display types now have an into_styled function that converts those types into a Styled, erasing type parameters.
• Even more methods are now const.

Changed

• The Color and DynColor traits are now explicitly marked sealed (i.e. downstream crates cannot implement them).

  These traits were already effectively sealed due to a number of hidden methods that were not part of the API, but they are now explicitly so. In that sense this is not a breaking change, so it's being released under a new minor version rather than a major version.

[4.1.1] - 2025-02-22

Added

• The vast majority of owo-colors is now usable in const contexts.

Fixed

• Documentation for Stream is now rendered properly. Thanks purplesyringa for the contribution!
• Replace brittle const-promotion-based unsafe code with safe code. Thanks Manish for the contribution!

Other

• owo-colors now lives under its own organization, https://github.com/owo-colors.
