We'd like to announce the second release (version 0.0.1) of the attempt package, for handling of failures. This release has been made to work with the new control-monad-failure package[1] in an effort to standardize failure handling.

Notable changes to this release:
* The MonadAttempt class was fully redundant with MonadFailure, and has thus been removed.
* WrapFailure class has been moved to control-monad-failure (with minor modifications).

* Data.Attempt.Helper (safe versions of some functions) has been moved to safe-failure[2].
* Full support for the monadloc package[3] to get monadic stack traces.

As usual, this release is available on hackage[4]. API stability cannot be guaranteed with this release as well, but we're getting much closer to hitting the mark.

All the best,

Michael Snoyman, Nicolas Pouillard
