Line 31:

* Changed the specification which hid wireless networks using TKIP security from the network search results. Wireless networks using TKIP security will now display in search results as a grayed-out selection instead of not being displayed

** The Nintendo Switch console supports WEP, WPA-PSK(AES), and WPA2-PSK(AES). If your router is using a different security type (e.g. WPA-PSK(TKIP)), you will need to change this security type within your router's settings.

==Unofficial Changes==

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

==System Titles==

Line 37:

Line 40:

* 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).

Line 67:

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.
