There are some discussions a few pages back about which API version to use. In short: use the one that the module was written for. The latest version of the module shows that for easy reference.
Thanks for your reply, but I'm still left with my original question: Should I be concerned about upgrading the plugin to the latest version, or just go with what is working just fine? (You know the old saying, "If it ain't broke, don't fix it!)
