Today we’re shipping Bootstrap v4.4.1!

In v4.4.0, we added add() and subtract() functions to avoid errors when using zero values in CSS’s built in calc() function. While these functions work as expected with our build system, which is based on node-sass, some alert developers noticed that things broke when using another Sass compiler like Dart Sass or Ruby Sass. To resolve this issue, we’ve tweaked these functions a bit to output what we would expect.

Lastly, we also added a theming fix for some custom forms in a disabled fieldset.
