I noticed 5.4 upgraded to Bootstrap 3.3.1 last month so I headed over the Bootstrap blog to see what’s in the new version. Along with info about the release there are comments about the upcoming 4.0 release. There’s not much info and no schedule but from past experience I would expect a Summer release and little to no backward compatibility. It also states V3 will only be maintained for a few months after 4.X ships.
I’m curious about how this will affect 5.4. From the brief description it appears V4 will require Tapestry component changes. It also drops support for IE8. Will/should 5.4 switch to 4.X when it comes out? For me if the changes are about the same as 2.X to 3.X I would expect a couple weeks work to make the required changes and some differences in the look and feel. I’m OK with that but the lack of IE 8 support has me a bit worried. Microsoft appears to be dropping IE 8 at the beginning of 2016 so that would mean I’m about 6 months ahead of that. Related to this does it make sense to switch to jQuery 2.X if the default styles do not support IE8? I think I’m OK with giving up on IE8 but I’ll like to see IE 8 render a Bootstrap 4.X site before I really decide. What do you think?
