We have print proof copies in hand. We appear to be on track for approving the print version for sale by May 1st. We also learned a few lessons by doing this essentially backwards through Amazon (KDP then Createspace) and will be implementing that fix with Issue 2, which you should expect in July 2017.
We have also sent out acceptances for Issue 3, and contracts for those contributors will go out shortly. We anticipate re-opening for submissions sometime this summer.
