Actually, 1.2.1 is out (and marked stable).=A0 I see = no reason not to upgrade.

As far as performance goes, when I upgraded our cluster from 1.0.= 4 to 1.1.2, our small jobs (that took about 1 min each) were taking about 2= 0-30s less time.=A0 So there is definitely some performance enhancements!

Like Hars said, the release notes described every bug fix, minor or
major improvements with the link to the related JIRA for each one.

Just a simple question? Why not upgrade directly to 1.2.0?
There are lot of good improvements and bug fixes here too.

See the Release notes here:
