==System Titles==
All updated New3DS-only titles except for [[NVer]] and NATIVE_FIRM were switched to the new NCCH crypto.
The following system applications were updated: System Settings, eShop, and System Transfer.
The New3DS-only placeholder menu system-application was updated(still a stub).
The following system applets were updated: Home Menu, error applet, mint, Miiverse applet, amiibo Settings, and the New3DS [[Internet Browser]].
The following system-modules were updated: Config, GSP(Old3DS/New3DS), PTM(Old3DS/New3DS), Download Play, HTTP, NIM, SSL, IR, NS, act, and NFC(Old3DS/New3DS).
The following CFAs were updated: 0004009B00010402, 0004009B00012302(and the equivalent non-USA-region titles), NGWord bad word list, Nintendo Zone hotspot list, [[NVer]](Old3DS/New3DS), [[CVer]], and 0004001B00018002. [[CVer]] had a [[CVer|new]] file added to RomFS.
The Old3DS [[Fangate_updater]] title was updated.
Old3DS/New3DS NATIVE_FIRM was updated.
Many other titles were updated/added for only KOR-region.
===New3DS NATIVE_FIRM===
====arm9loader====
The arm9loader was updated.
Old version of firm generated and initialized keyX for keyslots 0x15, 0x16, 0x18-0x1F. This version keeps the old algorithm for keyslots 0x11, 0x15, 0x18.
For keyslots 0x16, 0x19-0x1F it uses a new key for keyslot 0x11, but the actual algorithm has not been changed. This time the keyslot 0x11 seed is loaded from (nand_sector96+0x10) instead of (nand_sector96+0). They also changed the initialization vector for the 0x19-0x1F key-generation to a new hardcoded key.
Since we don't know the decrypted value at (nand_sector96+0x10), we don't know the new key for keyslot 0x11, and we cannot generate keys for the updated keyslots 0x16, 0x19-0x1F. Thus they plugged their hole and we can no longer decrypt arm9-binary without an arm9 code-execution exploit compatible with 9.6.0-X or <tricks where some of these *require* nand-modding>.
On panic, arm9loader now clears keyslots 0x15, 0x16, 0x18, 0x19, 0x19-0x1F. Previous versions only cleared 0-7, 0x15, 0x16.
====Process9====
The only actual code change for New3DS-only Process9 was that support for a new [[NCCH]] crypto flag 0xB was added.
===NATIVE_FIRM===
===NATIVE_FIRM===
The arm9loader was updated, new crypto it seems. On panic, arm9loader now clears keyslots 0x15, 0x16, 0x18, 0x19, 0x19-0x1F. Previous versions only cleared 0-8, 0x15, 0x16.
The ARM11-kernel and Process9 were updated. All of the ARM11-modules were updated, FS-module had the most changes among these modules.
The following is all of the changes for the (Old3DS) ARM11-kernel:
* 4 functions all with the same following changes were updated, one of these functions is called by [[SVC|svcWaitSynchronization1]]. Code was added which checks whether a certain s64 variable is <=0, when it is the variable value is set to 0x7FFFFFFFFFFFFFFF.
* The only other updated function appears to be memory related?
