Vecna has publically released a roadmap of how v3's release will progress. Read about it here.
For those of you who haven't noticed, there's three games/demos already released using v3:
- Timeless: vecna's v3 image tech demo (also very pretty and mesmerizing)
- Zaril's salute to even older demoscene demos (it must run in his swedish blood)
- Pulser, a compo game by Tatsumi, Zeromus, and Toen. It's a weird oldschool arcade game that demos the multiwin capabilities of v3. Zero promises more versions in the coming weeks... we'll see ;)
There's no docs out yet, as explained in the roadmap post. However, for the more adventurous, there's a copy of timeless with the source available. Any brave souls that make something neat with v3 without any documentation will get a forum avatar, and perhaps some other form of undisclosed recognition...
