With thanks to the @switchbrew team, Atmosphère 1.11.1 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:
* Basic support was added for 22.1.0.
* General system stability improvements to enhance the user's experience.

And the following was changed in 1.11.0:
* 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.
