How about the following?
(1) Identifying the exact version number of Atlas 2 to which you refer
-- in your message and on the DigiArea web site?
With my licensed copy of Atlas 2, in the Documentation Center page
guide/InstalledAddOns, I see that I am running Atlas version 2.3.0. And
the "Update" button in the "Manage" section for that item on the page is
not highlighted, so _presumably_ I have the current version.
(2) Providing an easy way to tell within Atlas what the version is.
In fact, it should be a "law" for any commercial or free add-on: within
the context of the add-on, include a variable that returns the version
I tried some poking around in the Atlas add-on files themselves, but in
Atlas.m I see:
(* :Package Version: 2.0 *)
(* :Copyright: Copyright 2011, DigiArea, Inc. *)
(* :Mathematica Version: 8.0 *)
So how am I supposed to tell easily what version is really there?
Add-on providers, especially commercial ones, should be subject to 10
lashes from a wet spaghetti if they fail to include such a function.
