7.0.0 RC2

Changed features

• tuned function0Instance and function1Instance (backport of #319)
• optimisation for Future.run (backport of #320)
• fix ambiguity for Functor instance in OptionT and IdT (backport of #322, 0fef6e514f)
• add Traverse1 and Foldable1 ops to the all-ops trait (backport of #327)

Incompatible changes

• Unapply: instead of just a conversion, require a Leibniz instance (backport of #325)

  Migration strategy: If you define your own Unapply instances, it is probably as simple as removing apply and adding the line def leibniz = refl. See the commit in the pull request for examples.

• remove ^ method from FunctorOps (backport of #326)

  Migration strategy: use map or one of the other countless aliases instead
