==System Titles==
All 01000000000010XX titles and most 01000000000008XX titles were updated. Some 8XX titles were just rebuilt with the new NCA crypto without actual RomFS-content changes.

* 0100000000000824(Mariko Config), 0100000000000825, 0100000000000826 were added.
** 0100000000000824 provides configuration for the new "T214" SoC.
** 0100000000000825 contains an empty "/blacklist.dat" file.
** 0100000000000826 contains a 0x40-byte "/version" file, this is all-zero except for '0' at offset 0x20.

The only 8XX titles with actual changes are (besides sysver-title, see below for FIRM):
* 801 (Support Error Codes)
* 803 (web-applet "shareddata:/")
* 804 (HTML resources for "Intellectual Property Notices" / "Health & Safety Information")
** "/legallines.htdocs/index.html" was updated with a Twitter mention, and a license section for "Software License for The Fraunhofer FDK AAC Codec Library for Android" was added.
** "/safe.htdocs/html/EU{XX}/index.html" was updated.
* 806 (Bad words)
* 807 ([[Hotspot List]])
** This was updated with more hotspots (these networks use encryption): "nintendoappdebug1", "Nintendo App Debug2", "Nintendo App Debug3", and "NCL-NZSERVICE1-5GHZ".
* 80A (Chara)
* 80B (Offline news)
* 80E (Geo Zoneinfo)
* 810-814 (All fonts)
* 818 (System-config)
* 81E (Controller gfx/icon data + dummy file)
** "/lyt/ColorTable" and "/lyt/footer/controllerIcon.bntx" were updated. The "01-00" image showing handheld-mode with detached joy-cons was replaced with a blank image.
* 81F (Icosa system config)
* 820 (Copper system config)
* 821 (Hoag system config)
* 822 (Firmware binaries for peripherals)
** The following was updated: "FirmwareInfo.csv", "tera_ota.bin", "tera_ota_iap.bin", and "ukyosakyo_ep2_ota.bin".
* 823

The built codebins now have padding in .text after every function for 0x10-byte alignment (and other compiler changes).

The SDK included with titles (main-codebin) for NV changed/updated NVIDIA hw strings:

===FIRM===
All FIRM titles were updated, and everything under RomFS was updated.

A new folder "a" was added, in addition to the existing "nx" folder, containing a separate "bct" and "package1". Both of these seem encrypted/meant for the new "Mariko" hardware that support was added for.

The following firm-sysmodules was added to both safemode-firm, which were originally in separate sysmodule-titles: [[Bus_services|Bus]], [[PCV_services|PCV]], and [[PSC_services|psc]].

====Secure Monitor====
The [[Memory_layout|Memory layout]] was changed significantly:
* .text, .rodata, and .data are now separate sections, mapped with correct permissions (RX, RO, RW, respectively), instead of being mapped RWX.
* Physical layout in TZRAM changed significantly, with pk2ldr being in low TZRAM instead of high TZRAM, etc.

In addition, there were changes to the [[SMC]] interface:

* smcGenerateSpecificAesKey was updated to support generating previous 4.x+ device key(s).
* smcLoadSecureExpModKey/smcLoadRsaOaepKey/smcDecryptRsaPrivateKey no longer exist.
* smcLoadRsaOaepKey was replaced with smcEncryptRsaPrivateKeyForImport.
* smcDecryptRsaPrivateKey was replaced with smcDecryptOrImportRsaPrivateKey.
** All keys which were previously imported with specific keys now first call smcEncryptRsaPrivateKeyForImport with the appopriate enum member to get a sealed copy of the RSA key, then smcDecryptOrImportRsaPrivateKey to import/unseal the key when needed.
* smcGetConfig was extended with two new config items:
** GetConfig(16), which seems to check whether the Switch is running on a Tegra 210:
return (FUSE_RESERVED_ODM4 & 0x800) && FUSE_RESERVED_ODM0 == 0x8E61ECAE && FUSE_RESERVED_ODM1 == 0xF2BA3BB2 ? (FUSE_RESERVED_ODM2 & 0x1F) : 0
** Getconfig(17), which returns the Package2 hash if booting from recovery mode.

<fill in the rest later>

====Kernel====
* Kernel Address Space Layout Randomization was added.
** Instead of using a hardcoded address for per-CPU region, they now use x18 to point to the per-CPU region.
* When using most [[SMC]]s, IRQs are now disabled first then restored to original state afterwards. x18 is also reinitialized right after most SMCs (see above).
* 5 new syscalls.
** Syscalls 0x48+0x49 (svcAllocateUserHeapMemory+svcFreeUserHeapMemory) are used by [[AM_services|AM]]-sysmodule.
*** This is used to allocate Application pool.
** Syscall 0x4A (svcSetUserHeapMemoryAllocationMax) is used by [[Process_Manager_services|PM]]-sysmodule.
*** This allows PM to set a limit on the number of bytes AM can allocate from Application pool.
** Syscall 0x6F (svcGetMemoryInfo) is used by FS, SM, and PM.
** Syscall 0x2E (svcGetNextThreadInfo) was added, but it only works on dev units.
*** Allows fetching how many bytes free/occupied by the different pools.
* NPDM irq_id's are no longer checked to be < 0x100, instead max-value is loaded from per-cpu state.
* The order slabheaps are laid out in memory is now randomized.
* There are now 4 memory pool partitions.
** This fixes sysmodule takeover with GMMU hax.

===[[Internet Browser]]===
OSS/WebKit was updated.

In the [[NPDM]], besides the RSA region the only changes were the kernel-release-version descriptor + {new ACID flag is set}.

In the "shareddata:/" title, the NROs are now compressed: "{name}.nro.lz4" instead of "{name}.nro".

===[[qlaunch]]===
RomFS changes:
* "/common/shader/VarietyOceanShader_Nx.arc.szs" updated
* "/lyt/common.szs" updated
* "/lyt/DummyGameA.szs" and "/lyt/DummyGame.szs" were removed.
* "/lyt/Entrance.szs" updated
* "/lyt/Eula.szs" added
* "/lyt/Flaunch.szs" updated
* "/lyt/Gift.szs" updated
* "/lyt/Interrupt.szs" updated
* "/lyt/Migration.szs" updated
* "/lyt/Notification.szs" updated
* "/lyt/Option.szs"
* "/lyt/ResidentMenu.szs"
* "/lyt/Set.szs"
* "/message/" Everything under here was updated.
* "/message/Ocean.msbp.szs" added
* "/sound/qlaunch_action.bksnd" and "/sound/qlaunch.bfsar" were updated.
* "/texture" Directory was added, which contains images for Nintendo Switch Parental Controls:
** "IcoPctl.bntx"
** "LogoMoon{region/language-text}.bntx", for every region/language.

===System Config===
New fields were added to [[Settings_services#System_Config|System Config]].

==[[NPDM]]==
New flags bit2/bit3 were added to the flags at ACID+0xC.

==Keys==
[[Flash_Filesystem|Keyblob]] 5 is now used, instead of 4. New NCA keydata is now used as well.
