[Switch] Atmosphere v0.8.3 disponible

• A custom warmboot firmware was implemented, which does not perform anti-downgrade fuse checks.
  • This fixes sleep mode when using a downgraded NAND.
  • This also removes Atmosphère's final dependency on Nintendo's encrypted PK11 binary; all components are now re-implemented.
• The ExternalContentSource API was changed to not clear on failure.
• Content override now supports an "app" setting, that causes all applications to be overridden with HBL instead of a specific title.
  • Note: because override keys are system-wide, using this setting will prevent using mods in games (as every game will be HBL).
• A bug was fixed causing incorrect fatal-error output when svcBreak was called on 5.0.0*.
• An extension was added to set.mitm to support customization of system settings.
  • These are controlled by atmosphere/system_settings.ini, see here for documentation.
• An extension was added to sm, adding a new sm:dmnt service.
  • This can be used by a debug monitor in order to debug the registration state of various other services.
• A bug was fixed in the MitM API that could sometimes cause a system hang during boot.
• A change was made to the MitM API: in cases where sm would have returned 0xE15 when installing a mitm service, it now defers the result (following GetService semantics).
• Support for booting into maintenance mode by holding */- was added to PM.
• An extension was added to exosphere, adding a custom SMC that allows for DMA to IRAM.
• In addition, smcGetConfig was extended to reboot to a payload in IRAM at 0x40010000 when ConfigItem 65001 is set to 2.
  • Fatal will now use this to reboot to sdmc:/atmosphere/reboot_payload.bin if present, when a vol button is pressed.
  • An example homebrew ("reboot_to_payload") was also written and is now included with Atmosphère.
• General system stability improvements to enhance the user's experience.
