# ChangeLog / ReleaseNotes


## Version 2.1.0.0

* Builds on GHC from 7.4 to 7.10, later with base 4.8. (change)
* Bumping transformers bounds to include 0.4.\* versions. (change)
* Dropped last threads of support for base <= 4.5; it hadn't worked anyway
  since [exceptions][] ==0.6 depend on base >=4.5 && <5. (breaking change)
* Instances for [mtl][] >=2.1 package. Package [exceptions][] already depends
  on [mtl][], so it doesn't make sense to shy away from them. (new)
* Introduced unsafe functions (new):

    ````Haskell
    liftCCLike
        :: (((a -> m b) -> m' c) -> m'' d)
        -> ((a -> Throws e m b) -> Throws e m' c) -> Throws e m'' d

    liftEmbedLike
        :: (forall a. m a -> Throws e n a)
        -> Throws e' m b -> Throws e n b

    liftHoistLike
        :: (forall a. m a -> n a)
        -> Throws e m b -> Throws e' n b
    ```

* Documentation updates. (new)
* Uploaded to [Hackage][]:
  <http://hackage.haskell.org/package/tagged-exception-core-2.1.0.0>
