I've not yet seen anyone try to create an ultimate list of *all* the new features in CF10, so here's my shot at it. (This is based on the public beta. I will update it soon with info from the final release.) Of course many (including Adobe) have created lists that show perhaps a couple dozen of what they think may be the most prominent features, or the most interesting for them, etc. I've just not yet seen anyone list even simply all the features mentioned in the beta new features guide. That's what I'm doing here.
But to be clear, I am not listing every new tag and function (that would be tedious.) Instead, I'm listing them as concepts, and where warranted, any relevant subtopics that expand on the new feature.
I've got more to say about the list (how I created it basically from the 244-page CF10 new feature docs, and what you can do to help expand it). But some will want me to cut to the chase, so here's the list. Please check out the additional discussion after it.
