text-hide() warning message

Created by: arechsteiner

When building the new 4.1 scss source code, I get the following warning message:

alex@ubuntuVM:~/code/bootstrap-41/scss$ scss bootstrap.scss  bootstrap.css
WARNING: The `text-hide()` mixin has been deprecated as of v4.1.0. It will be removed entirely in v5.
         on line 10 of mixins/_text-hide.scss, in `text-hide'
         from line 57 of utilities/_text.scss
         from line 14 of _utilities.scss
         from line 41 of bootstrap.scss

It seems text-hide() ist still used in https://github.com/twbs/bootstrap/blob/v4.1.0/scss/utilities/_text.scss#L57
