scalaz 7.0.4 released

[Lars Hupel]

Just staged on Sonatype:

"org.scalaz" %% "scalaz-core" % "7.0.4"

for Scala binary versions 2.9.2, 2.9.3 and 2.10.

This is a maintenance release for the 7.0.x series. It's a drop-in
replacement for 7.0.0 which is fully* binary backwards compatible
(tested with MiMa)! We also fixed two problems which made the MiMa check
incomplete in 7.0.3 and earlier.

There are two exceptions to the rule, though:
* New methods have been added to sealed traits, which is fine if nobody
extends those traits using Java.
* New methods have been added to the trait Future. See #542 for a
discussion.

That means: Libraries compiled against 7.0.x will continue to work
(without recompilation) with version 7.0.4. However, the inverse
direction is not supported.

This release contains a lot of bug fixes (notably for `==>>`) and a few
new features. Please refer to the release notes in the wiki
<https://github.com/scalaz/scalaz/wiki/7.0.4> for a full list.
