Hi Scott,

We've been looking at ExtJS 5 and expect to adopt it, but there's no specific timeframe yet. As you probably already know, we have a mix of ExtJS 3 and 4 in use in the core codebase, and both are still available for other modules to use. In the meantime, you can always add ExtJS 5 or other JavaScript libraries within your own modules (though you'd want to be sure to use a "sandbox" to avoid namespace collisions).

Separately, we are committed to supporting IE 11. We have made some fixes since it was released in 2013 to improve our support. If you're aware of current problems with IE 11 support, please let us know!

Thanks,
Josh

My issues were fixed with CSS changes. I can ask the other developers what they've encountered. I seem to remember hearing about other types of issues.

Have you tried adding the workaround suggested here to here Ext JS patches?

Hi Scott,

I've opened an issue to make sure that we do something for the ExtJS IE detection code:

Hi Scott,

We've committed the ExtJS patch. Right now it's in the trunk, meaning it will be part of 15.1. If there are specific cases under 14.3 that would be improved with this, please let us know and we can backport if needed.

Thanks,
Josh

Thanks Josh. I appreciate that.

Talking with the other guys, the issues we saw in 14.3 were fixable via CSS. We didn't get to everything, just what was the most problematic.

This was one of the more informative pages I found regarding the changes in IE 11:
