Sadly, the version linked on the original post is still the latest released version. I still plan to release an update, but as I only really get to work on LBGUI during the holidays between semesters and I have become a terrible procrastinator on working on LBGUI I often waste most of the holidays when I finally get back to it I spend most of the time I have getting back into the code. I'm kinda ashamed to see that my last post about this is already two years old...

Basically, you should treat the update for LBGUI like The Winds of Winter. You know that it's coming, but don't expect it to come soon. Then you can only be pleasantly surprised.
