It appears Sony is on a role lately, first releasing PS3 OFW 4.82 after quite some time and now they've pushed a PlayStation Vita Firmware 3.67 update live with the changelog incoming but expected to reflect their previous 3.65 revision by improving System Software stability once again.

While Sony's official site isn't updated just yet, as soon as we hear from PlayStation Vita scene developers we'll update this article with what's changed or patched in the PS Vita System Software 3.67 update.
Main features in system software update version 3.67
No DMA in the Wifi chip, so any exploit there would be useless anyways.
Yay, my browser stuff still working, neat
So yea, probably an useless update, Someone was bored at Sony
Crap, forgot to check _everything_ I suspect there is something else... don't update if you're on 3.65.
Account switching still works on 3.67 lol
So it seems some stuff releated to CMA was changed in 3.67 since now it checks the license file for content being copied to the vita from CMA (which means no hidden applications and you cant "Install" DRM content that isnt owned by your account.
also it seems PFS is now enforced everywhere (like it was for ux0:patch. just now for ux0:app too!)
(if you want to continue switching accounts on 3.67, simply use "Get Sign Up App" from http://vitatricks.tk) as this is not patched
If you are currently on 3.65 do not update to 3.67 because it _may_ (not confirmed) have fixed an exploit.
It's useless on its own but paired with an exploit chain, it would allow for persistence. No, I don't have such a chain.
Looks like I wasn’t clear before: there are no 3.61+ hacks anywhere, private or otherwise, period. People claiming otherwise are liars.
Someone is gonna have to find and exploit ~4 vulnerabilities before there’s even a chance of a 3.63+ hack and ~5 for 3.67 hack.
