FreeNAS 11 and iocage-style plugins: pkg repo?

I'm setting up a new FreeNAS box, and started experimenting with the new iocage-style plugins.

I was a little surprised to see that they resolved to relatively old packages. Plex Media Server, for example, was on the 1.4.4 series.

Is there a policy or goal around this package repository to keep things stable versus bleeding edge?
