Hi team, Last year Twitter announced the new version of Bootstrap. Wok currently uses a customized version of Bootstrap 3 Sass / SCSS files and looking at the Alpha code it seems that porting Wok to the new version won't be difficult: http://v4-alpha.getbootstrap.com/migration/ -Browser Support: Ok! -SCSS environment: Ok! -Dropped glyphicons: Ok! We already use Font-Awesome - Non-responsive usage of Bootstrap is no longer supported: Ok! I recognize some classes from this document and I think that a minor drawback would be with the Media Queries that were already implemented throughout the application and some changes with the classes names. Ginger uses a lot of "panel-" classes that were replaced by "cards", the "btn-default" button was renamed to "btn-secondary" and etc. The major issue is with jQuery Bootgrid plugin. It seems that they're not planning to port to Bootstrap 4 until it gets stable. I think we should port our jQuery Bootgrid code to Datatables.net, since it has a vast documentation and it already supports Bootstrap 4: https://datatables.net/examples/styling/bootstrap4.html Any comments?
