7.1.0 M6

This release is not binary compatible with 7.0.0 and previous milestones in the 7.1.x series.

Built against Scala 2.9.3, 2.10.3 and 2.11.0-RC1.

Note that these lists are not cumulative!

New features

• specialized aliases for subst on Leibniz and Liskov (#640)
• filter method on OptionT (#643)
• function to transform an arrow under an isomorphism (#646)
• dimap method on Profunctor (#647)
• liftFU on Free which infers the nested type constructor (a7bab4bf65)
• whenM, untilM, forever (#653)
• instances for Coyoneda (#652)
• catching combinators on MonadCatchIO (#663)
• specializied sequence for Free (#658)
• constant functor and polymorphic constant function (#657)
• instances for LiftIO and MonadIO (#661)

Experimental/Subject to further changes

• ISet: port Data.Set from Haskell (interface is probably stable) (#641, 2147f9417e, e2ed8cddc4, 41a841bfe9)

Changed features

• various performance optimizations (758d43ac5f, cd3fc71300, d59f3a49f1, b2acf67f49, 949b90fb19, 4a16dc3be2)
• constraint fromTryCatch to catch a specific Throwable (#605)
• generalise Nondeterminism gather to use Reducers (#650)

Deprecations

• scalaz-xml: The whole module is now deprecated.

  Reason: This module should not live inside the main scalaz project. If there are any users willing to maintain it, it can be resurrected as a project under the scalaz umbrella (cf. scalaz-geo).

  Plan: The module is not actually marked with @deprecated. The last release shipping it will be 7.1.0. Since 7.1.x will be binary compatible with 7.1.0, it can still be used with the 7.1.x series.

• fromTryCatch, replaced by fromTryCatchThrowable (#605)

  Reason: This method catches fatal throwables

• old, manually-importable MonadIO and LiftIO instances for StateT and Kleisli (#661)

  They are now in the respective companion objects and are picked up automatically without importing.

Build changes

• build with Scala 2.11.0-RC1 (78ff758d63, 2d2802af07, d354358ed1)

Incompatible changes

• curry zipWith on Free for better type inference (5cba367955)

  Migration strategy: trivial
