Given the nature of Github,you could also download the newly changed but not yet publically released versions right now if you have a C++ compiler. I've yet to try this out though.
Some of the devs know already that there hasn't been an update in while,but I don't think any of them are in a rush to release a new update. Most of the TPT devs are not paid ones, and quite a few of those that have contributed code to Github are busy with other,more important things.
What ? simon is the only one who can public the update ? his last post was in March.
just wait if it takes this long it must be a good update (or they could have run out of things to update.
