Yes, they're taking ungodly long, that doesn't mean the mod is dead. Three months doesn't seem much when put against the total time it's been since the last update.
Just play HIP or Ck3 and maybe theyll eventually release something.
last time they released a stable version was after jade dragon came out. holy fury broke the mod and we hadn't seen a stable release atleast 6 months before that, so we're talking 2.5 years total give or take outside of a beta release with bugs.
Point is, its been awhile and its going to be awhile longer. Just move on to something else for now.
