Once again, this is the same as the previous pre-release, recompiled to work with the latest atmosphere and HOS (0.19.4 and 12.0.3)
This release incorporates updates made to libstratosphere since the previous release that relax version checks, meaning that these updates to Mission Control for each minor Atmosphere release should no longer be required.
Since there appears to be some confusion amongst people... yes these pre-releases are stable, even on 12.0.0. I originally believed a lot of work may be required to support the bluetooth overhaul in 12.0.0 so labelled the release alpha to indicate that support was in its infancy. The issues I'd been having were mostly resolved in the 12.0.1 update and I kept the alpha label for consistency since I hadn't actually changed my code.
And finally, yes, I am aware that pairing of Wii/WiiU contollers is not working on 12.x.x. Please stop creating issues about it. Nintendo have added device class checks and changed how controllers using legacy pincode pairing are handled. I am looking into it. This is the final thing holding back a final 0.5.0 release, and it will likely require patching of the bluetooth module
