  • You can display a QR Code on-screen to check in using your Nintendo Account.
• Alarm Notifications have been added to System Settings > Notifications.

• You can now configure touch screen sensitivity settings.
  • Select between Standard and Stylus sensitivity (optimized for stylus input).
• Added the option to turn on/off the system button input (Nintendo Switch Lite only).
  • When this setting is turned off the system no longer receives input from the console buttons, with the exception of the Capture and HOME Buttons, and can only be operated from a wirelessly paired controller (sold separately).
  • This setting is on by default and can only be turned off if a compatible controller (sold separately) is wirelessly paired to the console.
  • The setting will automatically turn back on when the console is restarted or after returning from sleep mode.
• Added “Online Play Invites” section to the User's page.
  • Invites from friends to join online play in supported software will be displayed in this section.
• General system stability improvements to enhance the user's experience.
  • Resolved an issue where some users can’t start the Fire Emblem: Three Houses game, and get an error instead.

FIRM

All files in RomFS were updated.

NX_BOOTLOADER

NX bootloader was updated.

<check back later for diff>

Secure Monitor

Secure Monitor was updated.

• CPU Suspend SMC code now explicitly initializes the state of I2C5 before communicating with the PMIC, instead of assuming that it is in a valid state.
• Code for initializing MMIO inside package2ldr now writes random values to a number of PMC secure scratch registers, and validates that the written values are read back successfully before locking the scratch.
  • This writes to secscratch 4-7 (used to store SRK), then locks them.
    • The SE will overwrite these values during context save despite the lock.
  • This then writes to secscratch 112-115 and 24-25, used by TZ during context save to store a MAC and a key source, respectively.
    • These too will be overwritten during context save, as the scratch are not locked.
  • secscratch 4-7 are then locked a second time.

KernelLdr

KernelLdr was updated.

• TPIDR_EL1 is now set to 0, and VBAR_EL1 is now set to a table that infinite loops on all exceptions other than synchronous from same exception level.
  • synch_spx_el1 now restores a number of registers from a context with pointer in TPIDR_EL1.
• TPIDR_EL1 is now set to a context save struct before manufacturer-specific system registers are set, and validated to be non-0/NULL afterwards. It is then cleared.
  • Support was added for Cortex-A53 specific CPU initialization.
• Kernel .rodata is now initially mapped as RW- instead of R--, and then reprotected to R-- after relocations are completed.
  • This allows for/implements .rel.ro.

Kernel

Kernel was updated.

• Starting with this version, Kernel .rwdata is now 0x1000 aligned instead of 0x10000 aligned.

FS

Gamecard ASIC firmware was updated.

A new field "AcidSignatureKeyGeneration" in the NPDM format is now used to select between different public keys for verifying the ACID signature.

Loader

The anti-downgrade code in CreateProcess was updated.

• All system modules, and all web applets are now subject to anti-downgrade restrictions.
• Instead of using 1 as the minimum value, the minimum value is looked up from an array in .rodata on a per-module basis.
  • All current entries use 0x24000000 (9.0.0) as the minimum version.

Boot

Code was added implementing (partial, unfinished) support for a new hardware form-factor. Hardware type for this is 4 ("Calcio"), uses Mariko SoC.
