Full Release Notes
**1.11.0** is Atmosphère's ninetieth official release.
**Please be sure to update fusee when upgrading to 1.11.0**. fusee-primary no longer exists, and will not work any more.
With thanks to the @switchbrew team, Atmosphère 1.11.0 is bundled with [hbl](https://github.com/switchbrew/nx-hbloader) 2.4.5, and [hbmenu](https://github.com/switchbrew/nx-hbmenu) 3.6.1.
The following was changed since the last release:
* Support was added for 22.0.0.
* Special thanks to @alula for handling a large chunk of the necessary kernel, loader and erpt changes.
* The console should boot and atmosphère should be fully functional.
* **Please note**: A change in how applications/applets' lifespan is managed broke the homebrew ecosystem.
* All applications and applets are expected to perform a clean exit by calling the relevant IPC commands.
* Homebrew compiled with libnx and hbmenu itself explicitly avoid exiting so it can keep using the same process.
* Properly fixing this would require a re-design of how homebrew is launched and terminated.
* As a temporary solution, patches to the `am` sysmodule are now included which allow restoring the previous behavior and regain homebrew compatibility without any further changes.
* Nonetheless, please report any issues you may face when testing homebrew to ensure no edge cases have been missed.
* `exosphère` was updated to reflect the latest official secure monitor behavior.
* `mesosphère` was updated to reflect the latest official kernel behavior.
* `loader` was updated to reflect the latest official behavior.
* `erpt` was updated to reflect the latest official behavior.
* `pgl` was updated to fix a few issues.
* Support was added for memory modes above 4GB (thanks @CTCaer).
* A build time option to configure Joy-Con rails as UART for debugging was added (thanks @alula).
* General system stability improvements to enhance the user's experience.
