The first release supporting (and thus depending on a minimum of) Fabric Loader 0.7. Therefore also being designed for Mixin 0.8. Feature identical to 1.9.1 although with two important notes which likely make existing code incompatible:
ASM Lib Shift
Mixin no longer repackages ASM, thus the standard imports can finally be used in preference to the Mixin ones. Care should be taken to not leave any dangling references given Mixin's remaining stub implementation will crash at runtime.
Early Risers load from Entry Points
Although not a Loader 0.7 change, now that it is the minimum version Early Risers can be loaded as entry points now rather than requiring to be custom JSON entries. The old system also works, but using entry points is preferred. The required changes should be minimal.
