Zoph 0.7.2.1 released

I have created a bugfix release for Zoph 0.7.2: I found out that the 0.7.2 release that was released earlier this week did not include the latest version of some files. I also fixed 2 other bugs. For a full overview of the changes, see the changelog.

0.7.2.1 is still an unstable release. Download 0.7.0.4 if you're not comfortable with running an unstable release.
