[Kenji Yoshida]

Hi everyone.

I just released 4th milestone of scalaz 7.3 for Scala binary versions 2.10.x, 2.11.x and 2.12.0-M5.

"org.scalaz" %% "scalaz-core" % "7.3.0-M4"

This is NOT binary compatible with 7.2.x and 7.3.x milestones.

There are some new features and changes. please refer to the release notes

Cheers.
