I was working on a three month old build of 's plugin on 4.6.1 not too long ago if I remember right.
Yep, just checked my repository.

I think the plugin versions dated around December 2014 will work for sure with v4.6 and likely newer versions too. (But I never tried them) Just trying to be helpful.
