Atmosphère 1.12.0

on GitHub

1.12.0 is Atmosphère's ninety-third official release.

Please be sure to update fusee when upgrading to 1.12.0. fusee-primary no longer exists, and will not work any more.

With thanks to the @switchbrew team, Atmosphère 1.12.0 is bundled with hbl 2.4.5, and hbmenu 3.6.1.

The following was changed since the last release:

• Support was added for 23.0.0.
• Special thanks to @alula for handling the implementation of several kernel changes.
  • The console should boot and atmosphère should be fully functional.
  • Please note: As a result of changes made to nintendo's software in 23.0.0, there is even less memory available for custom system modules.
    • The amount of memory we can steal from the applet pool has been reduced beyond 7MB and we can no longer launch browser applets (e.g.: eshop) without crashing.
    • To compensate for this, a set of patches for the browser applets has been introduced.
      • Thanks to the redesign of the browser applets in 22.0.0 there are only 3 applets we need to worry about: systemWeb, openWeb and LibAppletOff.
      • With the added burden of maintaining patches for these applets, we can reclaim around 9MB of reserved memory by patching out their allocations.
      • This memory is provably unused and stealing it should not affect the browser applets in any way as the applets themselves tag it as reserved and never access it.
      • As a result, the memory available for custom system modules has been experimentally increased to 16MB.
      • Preliminary testing has seemingly shown no downsides to the overall functioning of the OS and the browser applets in particular.
      • Nonetheless, please report any issues you may face to ensure no edge cases have been missed and to determine if the memory amount needs to be adjusted.
      • These patches may be deprecated at any point in the future if a better solution is devised.
  • exosphère was updated to reflect the latest official secure monitor behavior.
    • A new ConfigItem was added to the secure monitor for the first time since firmware 5.0.0.
  • mesosphère was updated to reflect the latest official kernel behavior.
    • The kernel now supports a 42bit wide address space.
    • A new memory region dubbed ShadowStack has been introduced.
    • Kernel RNG was changed to CTR-DRBG.
  • boot was updated to reflect the latest official behavior and to implement a previously missing change.
    • The way battery i2c shutdown was being enabled changed in firmware 18.0.0 and we missed it.
    • It is possible this might have been related to a known battery draining issue reported to have started around firmware 18.0.0. Further testing will be needed to confirm.
  • loader was updated to reflect the latest official behavior.
  • erpt was updated to reflect the latest official behavior.
  • pgl was updated to reflect the latest official behavior.
  • ro was updated to reflect the latest official behavior.
    • NROs can now be lz4 frame compressed.
• ZBIC compresison/decompression has been properly implemented. Applications using it should now launch and work properly.
• A dockerfile has been added to atmosphère (thanks @alula).
• R_DISCARD macro has been adopted across the entire codebase where applicable. This finishes the work started in version 1.10.0 and eliminates the nodiscard warnings during compilation.
• General system stability improvements to enhance the user's experience.
