Over several recent tweets I have seen that Structr is restructuring its websites to better separate structr.com (commercial) from structr.org (open source) communities.
The upcoming structr release is 2.0 and is set for just before @GraphConnect (Oct. 21, 2015). Another tweet says there are lots of new features, full-text file and URL indexing, SSH/SCP support, a new Files UI etc.)
That makes October seem further away that it was just moments ago. 😉
