The new games that will be added in 1.7.0 are Chivalry Is Not Dead, Mortville Manor, Return to Ringworld, The Neverhood, and Voyeur. They have also changed their Adlib player for the DOS floppy versions of Indiana Jones and the Last Crusade and Loom, so they need your help testing these games as well.
If you own any of these games and would like to help out, then fire up ScummVM on your platform of choice and test. Let them know how you made out on the ScummVM forums and if you find any bugs, submit them on the ScummVM bug tracker. The results of testing will be posted on the ScummVM wiki.
In related news, keep an eye on the ScummVM Planet. The Google Summer of Code is going on now, ScummVM is a part of it again, and this year their sister project ResidualVM is involved too (with ScummVM acting as an umbrella for both projects). GSoC students are adding support for Sfinx and The Prince and the Coward to ScummVM, as well as improving support for Escape from Monkey Island and improving the TinyGL renderer in ResidualVM. They've already accomplished a lot on these tasks, so it will be really interesting to see what they manage to get done by the end of the summer.
