I've been a member of the development team since we first started work on 0.6, even though I couldn't help much (devkitpro just doesn't seem to work on this crap computer), I'm guessing it's OK for me to release the finished product.
Changelog:
*Keyboard functions added! Now DSLua can access PALib's internal keyboard functions!
*3D functions added! 3D graphics are now possible!
*Support for unconverted BMP, JPG, and GIF images is now possible!
*For Slot-1 device users, you can now access an official Nintendo DS Rumble Pak with DSLua!
*DLDI support added in full! Patch with a DLDI of your choice!
*16-bit backgrounds added!
*GBFS version fully removed, emulator testing is now sadly impossible. PACK.BAT is no longer part of the package.
*The multiboot menu has been removed due to coding problems, now DSLua automatically starts /scripts/main.lua (currently is a new multibooter).
