**0.8.1** is Atmosphère's eighth official release.

fusee-primary was last updated in: **0.8.1**.

The following was changed since the last release:
* A bug was fixed causing users to see `Failed to enable SMMU!` if fusee had previously rebooted.
  * This message will still occur sporadically if fusee is not launched from coldboot, but it can never happen twice in a row.
* A race condition was fixed in Atmosphere `bis_protect` functionality that could cause NS to be able to overwrite BCT public keys.
  * This sometimes broke AutoRCM protection, the current fix has been tested on hardware and verified to work.
* Support was added for enabling `debugmode` based on the `exosphere` section of `BCT.ini`:
  * Setting `debugmode = 1` will cause exosphere to tell the kernel that debugmode is active.
  * Setting `debugmode_user = 1` will cause exosphere to tell userland that debugmode is active.
  * These are completely independent of one another, allowing fine control of system behavior.
* Support was added for `nogc` functionality; thanks to @rajkosto for the patches.
  * By default, `nogc` patches will automatically apply if the user is booting into 4.0.0+ with fuses from <= 3.0.2.
  * Users can override this functionality via the `nogc` entry in the `stratosphere` section of `BCT.ini`:
    * Setting `nogc = 1` will force enable `nogc` patches.
    * Setting `nogc = 0` will force disable `nogc` patches.
  * If patches are enabled but not found for the booting system, a fatal error will be thrown.
    * This should prevent running FS without `nogc` patches after updating to an unsupported system version.
* An extension was added to `exosphere` allowing userland applications to cause the system to reboot into RCM:
  * This is done by calling smcSetConfig(id=65001, value=<nonzero>); user homebrew can use splSetConfig for this.
* On fatal error, the user can now choose to perform a standard reboot via the power button, or a reboot into RCM via either volume button. 
* A custom message was added to `fatal` for when an Atmosphère API version mismatch is detected (2495-1623).
* General system stability improvements to enhance the user's experience.
