To quote from Dukio.com (linked above): Well, I think it's going to be a good framework for any new enthusiastic developer who wish to start in the ever growing PS3 Jailbreak scene. Below are the changelog for the recent refactoring work that has been done by him to his PL3 git.
WIP: rename macros.h.S to pl3.h.S and make it do a lot more stuff
Make send_eth compatible with FUNC_PTR and add a _res variant
Add proper ifndef/define/endif to all .h.S files
Port all payloads to the new pl3.h.S framework
Factor out the code to hook the hvsc instructions into its own file
