See https://github.com/twbs/bootstrap/releases/tag/v4.1.0. A handful of new utilities added.

• new .flex-fill, .flex-grow-, and .flex-shrink- utilities.
• new .text-monospace utility.
• new .text-body (default body color), .text-black-50 (50% opacity black), and .text-white-50 (50% opacity white) utilities.
• new .shadow-* utilities for quickly adding box-shadows.
• new .w-auto and .h-auto utilities.

Hi there, nice back port! Finding it very useful on a couple of projects that are stuck in BS3.

I noticed that both /dist/bs4-utilities-for-bs3.css and /dist/bs4-utilities-for-bs3.css.min have some odd spacing.

*-1 = 5px
*-2 = 10px
*-3 = 12px
*-4 = 16px

According to the docs: https://getbootstrap.com/docs/4.0/utilities/spacing/ the default should be:

*-1 = 0.25rem
*-2 = 0.5rem
*-3 = 1rem
*-4 = 1.5rem
*-5 = 3rem

Your variables.less file seems to be correct, with @spacer-default: 1rem

Are the odd spacing sizes and use of pixel units somehow intentional?

Thanks, Cam

This release (https://github.com/twbs/bootstrap/releases/tag/v4.1.1) did not change any utility classes.

Should I still tag a release for version number parity?
