Wasn’t version 1.3.1 (22.214.171.1240) withdrawn?
That version was only available for very few days and then it disappeared... I removed my 1.3.1 and reinstalled 1.3.0 (126.96.36.1995) since I thought that the 1.3.1 version apparently was a mistake that it was released.
Of course, it would have been nice to know why 1.3.1 disappeared, but since no others apparently commented it before now, I thought it was best to forget that version. I probably expected it was only a matter of a few days before it was available again. It's about a month ago it was removed.
If no one from the dynamo team comment on this, then I would suggest you to install the 1.3.0 version.
I have on the other hand heard and seen that we can expect a version 2.0, but not much is written about that version on the github page, and there is no release date.
