Thanks to Netrix one critical issue was addressed this time, which was the problem of running out of memory using the standard JSoS modus operandi. Instead of defining all functions and variables immediately, additional scripts are now delayed from execution and run after the exploit has access to the full user memory space provided by the Vita.
A lot of new function wrappers were added and the batch tests' system was changed. In terms of design, it's now looking closer to a pseudo javascript based SDK.
You can find the sceMotion functions and the motion test as well, which became popular due to Brian's video demonstrating the Vita's gyroscope. The test simply prints the xyz coordinates of the gyroscope, but using the sceNet functions it's possible to send them back to the computer and write a simple application to read them (like the one showcased in the referred video).
The errors related to module loading should now be fixed as well.
