I noticed the npm repo is now on version 5 alpha line. And 4.1 stopped at beta 4. Are you guys not planning to release the fixes for 4.1? Specifically the IE ones. I was waiting on them so I can use the 4x line.
Thanks.

@ctrlplusb Should probably have some sort of migration guide for v4 to cover at least some of the basic changes that will be required after updating.

I just discovered that listeners on actions with .type stopped working and I had to remove all of them for just the action name.

The two biggest things I had to change were

1. listeners, actions => action.method.type --> actions => action.method
2. Persists whitelist: -> allow: and blacklist: -> deny:

I saw the notes about persist being pretty much a complete rewrite, but i didn't catch the listeners until testing and my loading states stop getting updated

Still working on integrating all these updates. My sincere apologies.
