1.6.1 is Atmosphère's seventy-sixth official release.

Please be sure to update fusee when upgrading to 1.6.1. fusee-primary no longer exists, and will not work any more.

Note: switch/haze.nro was updated in the release zip on 2023/10/16 at 3:40 PM PDT to fix an issue where haze could fail to work on Windows. The updated zip has a build hash of "7f4450f93".

Please note: Atmosphère 1.6.1 is currently in pre-release, and issues may be found that need to be fixed before full release.

• If any bugs are reported while Atmosphère is in pre-release, they will be fixed and the build will be updated.
• 1.6.1 will transition to release after a short amount of time has passed without pressing bug reports.

With thanks to the @switchbrew team, Atmosphère 1.6.1 is bundled with hbl 2.4.3, and hbmenu 3.5.1.

The following was changed since the last release:

• An improved solution to the problem that would cause consoles which had previously re-built their SYSTEM partition to brick on update-to-17.0.0 was added.
  • In particular, booting atmosphère will now automatically detect the problem and unbrick any consoles which have fallen into this state.
• Some improvements were made to haze, including:
  • Performance was greatly improved:
    • Support was added for GetObjectPropList, which decreases the amount of requests made by ~8x.
    • Haze now performs rendering on the GPU, freeing up the CPU to respond to requests in a more timely manner.
  • An issue was fixed with how haze configures bMaxPacketSize0 which improves support for USB3.
• General system stability improvements to enhance the user's experience.

And the following was changed in 1.6.0:

• Basic support was added for 17.0.0.
  • The console should boot and atmosphère should be fully functional. However, not all modules have been fully updated to reflect the latest changes.
    • There shouldn't be anything user visible resulting from this, but it will be addressed in a soon-to-come atmosphère update.
  • exosphère was updated to reflect the latest official secure monitor behavior.
  • mesosphère was updated to reflect the latest official kernel behavior.
  • ncm was updated to reflect the latest official behavior.
  • erpt was partially updated to support the latest official behavior.
• Atmosphere's gdbstub now supports waiting to attach to a specific program id on launch (as opposed to any application).
  • The monitor command for this is monitor wait <hex program id>, where program id can optionally have an 0x prefix.
• Support was added to haze for editing files in-place and performing 64-bit transfers (files larger than 4 GB).
• bpc.mitm was enabled on Mariko units, and now triggers pmic-based shutdowns/reboots (thanks @CTCaer).
  • This should cause the console to no longer wake ~15 seconds after shutdown on Mariko.
• A number of minor issues were fixed and improvements were made, including:
  • A workaround was added for a change in 17.0.0 that would cause consoles which had previously re-built their SYSTEM partition to brick on update-to-17.0.0.
• General system stability improvements to enhance the user's experience.
