You may already be aware of this but OPC is being update. You might review some of the latest unreleased fixes for 1.5.6a noted here.

The code changes are the easy part!

The hard part with v2.1.0 for OPC is documenting the process that you'll need to use when updating, as the majority of OPC's core/template file changes are now included in the zc156/zc156a (and to-be-released zc156b) distributions. I'm trying to create an overall set of procedures to be used when updating or performing an initial install for Zen Cart versions prior to zc156b ... it's kind of like "putting Humpty Dumpty back together again"!
