Nope, it’s still very much alive as a whole, and I still actively provide support/answer questions when they arise.
We’ve actually had some activity recently over on Github, where any development happens first, but I’m not sure if we’re at a point where we’re prepping for a new release just yet.
Thankfully, all in all, it’s still been pretty stable and usable with the latest versions of WordPress, so despite not necessarily having new releases, it’s a viable solution. I make heavy use of it on my own personal sites to this day, and am happy with it ??
