Bootstrap v5.0.0-alpha1

You may want to read Bootstrap's announcement on their blog.
The most importants part are: dropping jQuery and IE 11, and a new utility API which makes extremely simple to customize design tokens!

Boosted v5.0.0-alpha1

Boosted v5.0.0-alpha1 is basically Bootstrap's one, Orange branded. There're no Boosted custom components in v5 for now, but a few noticeable differences with Bootstrap:

1. using Helvetica,
2. improving focus visiblity thanks to :focus-visible polyfill,
3. defining a mininum contrast ratio of 4.5:1 instead of 3:1,
4. and obviously, branded components and core variables.

If you want to have a look at Boosted v5 roadmap, you'll find it in this repo's projects.
