Cleanup and moving forward to 4.0

Hi everyone, first up, please accept my apology for leaving this project in silence for a long time – sorry :) I know many of you are using this component and depending on it, so I don't take that lightly. Many have taken the time to report issues and create pull requests, and I appreciate your patience.

I'm going to put in some effort now to bring the project back to a healthy state, and also explore options of how to make that sustainable in the long term.

First up I'll be doing some triage on issues, to get a better understanding of where things are at. I'll also be merging some PRs that deal with updates to documentation and minor bugs.

Larger changes will be held just a little longer as more care needs to be taken towards backwards-compatibility.

And shortly I'll also be sharing my plans for a 4.0 release, and how you can help. Thanks!
