Notice for Everyone using AquaTouch v3

@Andreas_Hegenberg has rolled out some much awaited BTT features that i've been longing to implement into AQT.
These features will add further quality improvements and bug fixes, but will require you to update using BTT's Alpha release stream.
BTT's alpha versions are still in testing phase so it may be buggy. AQTv3 is also in testing phase too, so I guess we could all come together to help Andreas solve any bugs with the new features. More people = more tests!

AQTv3 will only be released when these new BTT features are released in it's stable release.

Thanks!

EDIT: I can't seem to update to the alpha. It's returning an "Update Error!" window
