Surprised this hasn't been posted yet. Apparently the author is ceasing development on RDX. There hasn't been an official announcement, the only information I could find is from this thread and related screenshot.
Yeah, there is a small group of people that are planning on maintaining it from patch to patch and do bug fixes as they come up, with possibly adding new features as time allows. Veni hasn't open sourced it yet, but said that he will be doing it shortly as well as handing over what code he had for RDX7. There is a handful of people familiarizing themselves with the codebase and going about documenting RDX more thoroughly. Just basically waiting for Veni to change the license on it so people can start getting it for free.
I believe someone took the liberty of publicly hosting the latest version on the offical site.
At present it won't be hosted on OpenRDX until an official release statement is posted by the author
I honestly wouldn't like to say. While I have the utmost respect for the author's coding capabilities, an official statement releasing the mod or atleast posting on the forums that RDX was no longer going to be maintained by him is only corteous as it was a paid membership
What I will say however, Grab the free download if you wish, theres a host of additional modules on the openRDX site to make the mod fully usable
