I wouldn't. While it still works (and I use it in a project of mine), the last commit is two years old and there are more and more open issues. It's a dead project.
On the other hand, using the flavour-of-the month JS shiny thing until the CADTs jump ship is also burdensome. There is a lot to be said for stable libraries, let-alone stable ecosystems.
Totally agree. But there is a difference between stable and dead. Bugfixes matter. Taking care of issues would mean that things like "FF 51 breaks the tooltips" (fictional example) gets discovered and fixed. And one or two improvements a years also don't hurt.
IMHO that's a good thing. It's not changing, works very well, has lots of plugins and is a relatively small library so you can fix it yourself. Plus a large user base, so many problems you run into are already known.
