- Implement callback functions needed by newlib - POSIX environment - Thread safe alloc/dealloc open/close files - Changed the way that HEAP is allocated, now by default it uses all available RAM except 512KB/ - Implement a lot of missing functions for having a real POSIX environment (some implementations are dummy because are impossible to do in the PSP OS) - Adding specific inet changes that previously where in the PSP newlib patch - Deleting the uncompleted & custom libc library - Create some weak functions during init of libc process to save some KB if we want to have tiny apps - Other I/O improvements
