eXtineDocu is so close to release. We are putting the final final touches on it but are also unfortunately waiting on word back regarding some distribution stuff.
I talked with Luc yesterday and without a doubt we'll be releasing before i49, even if we're still waiting. We set a hard date, but this isn't the proper place to address it.
To clarify in case anyone freaks out. The docu will definitely be free on YT, but we're also looking at different routes for distributing a 50fps HQ version.
Bittorrent is the way to go. I'm sure some people in this community have access to a seedbox which would help speed up the initial process.
