* Support for Wii U GameCube Adapter and Headsets [[List of compatible USB devices | over USB]]
* Added support for Wii U GameCube Adapter and Headsets [[List of compatible USB devices | over USB]]

==System Titles==
* Every single system title was updated, except for: 0100000000000805("Chinese and Korean dictionaries"), 0100000000000808("European, English and Japanese dictionaries"), and 010000000000080C("EULA").

* 4 new sysmodules were added, and new FIRM-package title 010000000000081C was added.

* [[Flog]] was stubbed: official code for launching it was removed from [[qlaunch|the home menu]], and *all* code was overwritten with garbage. Thus, even attempts to launch it manually will result in [[Loader services|loader]] returning error 0xA09.
==Kernel==
* Kernel startup code was updated:
** A new (unused?) function was added, this is roughly the same as the code which originally directly read a MC register (0x70019050) for [[Memory_layout|getting]] the DRAM size, except [[SMC]] ReadWriteRegister is used for the read instead.
** The code which originally read the above register directly was replaced with an inlined version of the above function.
* All RTTI symbols were removed, can no longer know official name of kernel objects. :(
* JIT syscalls were added.
** New MemoryType bit for "JIT allowed".
** New MemoryTypes for JitWritable and JitReadOnly.
* New synchronization syscalls 0x34, 0x35 added: These ones allow implementation of synchronization primitives without a mutex+condvar pair. This is more efficient because when a thread wakes up from a condvar, the mutex is held and needs to perform a syscall to unlock it. If you have N threads blocking on a condvar, you need N-1 syscalls to wake all the threads. With the new syscalls, you can wake up all N with a single syscall.
* Added new syscall svcDumpInfoNew, but it's stubbed.
* The linked-list node for KAutoObjects was added to the struct itself instead of being a separate allocation.
* svcGetInfo now exposes the first and last process id for built-in modules.
** This is used by some services to make sure we can't connect to them from outside a privileged module.
* svcReadWriteRegister was updated, now always goes through TZ for both PMC and MC. Whitelist for MC remains the same.
* Support was added for loading non-KIP processes into the Secure pool via a flag in SvcCreateProcess.
** This is used by only for es, to prevent attackers from using GPU DMA to take over the es sysmodule to pirate games.
** Correspondingly, the KHeapArrange calculation of the secure pool size now has an extra 0x13A000 factored in (to ensure there is enough space for es).

The package1 entrypoint address specified by BCT was increased by 0x20-bytes, since there's now an additional 0x20-bytes at the start of package1. The additional data is identical to the 0x20-byte block before it.

In SafeMode Firmware the [[Bus_services|Bus]], [[PCV_services|PCV]] and [[PSC_services|psc]] sysmodules are now bundled with the kernel.
Sysmodules:
* spl was updated to split the [[SPL services#spl:|IGeneralService]] ("spl:") into many usage-case specific services.
** spl: no longer contains commands for doing AES/RSA cryptographic operations
** spl:mig was added, supporting crypto commands used by the new migration sysmodule.
** spl:ssl was added, supporting crypto commands used by the [[SSL services|ssl]] sysmodule
** spl:es was added, supporting crypto commands used by the es sysmodule.
** spl:fs was added, supporting crypto commands used by the [[Filesystem services|fs]] FIRM sysmodule.
