On the Mendix reference pages, the Bootstrap version 2.3.2 is referenced. I believe I saw an news-message somewhere that said Mendix is now using version 3. I quote the text: "Mendix 5 adopted Bootstrap as its main css framework. Therefore all Mendix classes are renamed to conform to Bootstrap's naming conventions. By dropping support for Internet Explorer 6 and 7, we were able to simplify the DOM structure of widgets, which makes styling a lot easier." As found on URL https://world.mendix.com/display/refguide5/Moving+from+4+to+5 Which version is exacly being used in the current modeler? (v 5.6.2) And since when is the new version of Bootstrap supported? Where can I find this information?
