0.10.0

• Fix a regression in 0.9.0 whereby the non-IO effects in bracket’s use action were not visible to the release action, and the non-IO effects in the release action were not visible after the bracket call.
• The type of generalBracket was changed in order to restore those non-IO effects, so if you are a library author that provides a MonadMask instance, you will need to update your implementation of this method.
• Add MonadMask instance for MaybeT
• Add onError function whose action also runs on errors which are not exceptions, such as a Nothing or a Left.

0.9.0

• Add generalBracket to the MonadMask typeclass, allowing more valid instances.

  Note that functions such as bracket and finally are now based off of generalBracket, so if you are a library author that provides a MonadMask instance, you will need to provide an implementation of this method.

• Add MonadMask instances for ExceptT and ErrorT
