I need someone to do the usual process to verify the dist files, because I keep seeing changes in the CSS map files in some cases (on Linux, Windows is expected to have differences due to a bug in clean-css):
git checkout v3-dev-xmr
git clean -dfx
npm i
npm t
# here check about modifications with `git status`
npm run release
# check again here about modificationsChanges: https://github.com/twbs/bootstrap/compare/v3.4.1...v3-dev-xmr
