Log Message:
Update to monad-control-1.0.2.3

1.0.2.3
* Correct spelling mistake. Courtesy of Edward Betts.
* Support transformers-compat-0.6.

1.0.2.2
* Added some good documentation. Courtesy of Franz Thoma.

1.0.2.1
* Refer to Michael Snoyman's excellent tutorial on monad-control.

1.0.2.0
* Improve documentation by including type equalities in the Haddock
  documentation.
* Add helpers to define MonadTransControl for stack of two:
  RunDefault2, defaultLiftWith2, defaultRestoreT2

1.0.1.0
* Added the functions:

  liftThrough
    :: (MonadTransControl t, Monad (t m), Monad m)
    => (m (StT t a) -> m (StT t b)) -- ^
    -> t m a -> t m b

  captureT :: (MonadTransControl t, Monad (t m), Monad m) => t m (StT t ())
  captureM :: MonadBaseControl b m => m (StM m ())

* Added Travis-CI integration

1.0.0.5
* Support transformers-0.5 & ransformers-compat-0.5.*.

1.0.0.4
* Support transformers-compat-0.4.*.

1.0.0.3
* Unconditionally add ExceptT instances using transformers-compat.

1.0.0.2
* Add a base >= 4.5 constraint because monad-control only builds on
  GHC >= 7.4.

1.0.0.1
* Use Safe instead of Trustworthy. This requires a dependency on stm.

1.0.0.0
* Switch the associated data types StT and StM to associated type
  synonyms.

  This is an API breaking change. To fix your MonadTransControl or
  MonadBaseControl instances simply remove the StT or StM constructors
  and deconstructors for your monad transformers or monad.

* Add the embed, embed_ and liftBaseOpDiscard functions.

0.3.3.1
* Unconditionally add ExceptT instances using transformers-compat.
