Edit Orders and v1.5.0?

I'm using a lot Edit Orders module in my actual 1.3.8 version . Now I plan to migrate on 1.5.0 but can't find anything about the compatibility of this module with actual version or other module doing that . Please tell me that I don't have to delay the entire migration process because isn't a way to edit an order ...

There is a sticky at the top of the Upgrading from 1.3.x to 1.5 thread that gives a list of those mods that should work with 1.5.0.
Edit Orders does not appear to have been touched in over four years. Since it is deeply involved in the admin and order sections, I doubt the 1.3.8 version would work.
Edit Orders v3.0.3 is eighteen months old but, again, it is questionable whether any mod not advertised as 1.5.0 ready will work.

There is a version 4 of Edit Orders being developed as of July. Keep an eye on the Plugins for its release.

The sticky thread dbltoe mentioned has a status of the Zen Cart 1.5 compatible version of Edit orders posted (and yes that means you might have to search the thread to find it).. And the support thread for Edit Orders also has a BUNCH of threads which speak to the progress of the Zen Cart 1.5 compatible version. So yes there is information available. That's why shop owners should ALWAYS check the add-on's support thread for the latest information on compatibility..
