The widget disappeared

Since I updated to version 4.3, the widget stopped appearing in my available widgets list. Also, any instances I had of it at my sidebars just disappeared 🙁 It’s a pity because I really liked it!

I see there haven’t been any updates, but just in case you are interested in giving it some more life, it would be greatly appreciated.
