9.0.21 is a modification to the original 1.0.18. There hasn't been an appearance of the developer for months, but it would have been up to him to submit it to that group. That group is somewhat sensitive to accusations that it supports 'piracy' in their third-party apps from the 'Kodi" foundation, and unless the defaults that pointed to the NFPS Stalker middleware were removed, it probably wouldn't be acceptable. I think that group also doesn't like the iVue guide, mostly because it was developed for a customized box.
IPTV Stalker is like of like a pandora, and you can't get it back into the box at this point, and its kind of an orphan. Soon, the server people will make it obsolete, when they finally get around to using real passwords tied to donations. I don't know when that will happen, but I know its in the works. (pvr stalker already has the capability to accept passwords and usernames).
