GAAB...chill out. Developers typically don’t follow a classical, disciplined business model. As a result, the vast majority release updates....when they feel like it....and work on the projects....when they feel like it. You’ll save yourself a lot of angst if you can align your expectations to that mentality - i.e. decide to feel surprised and happy whenever they decide to release any updates...or when they decide to release any products for that matter. The good news is, despite the typically non-commercial development path, the wait is nearly always worth it!
Hang in there.
