Let's say there is a newspaper called "ACME News".
When they make a new "number" of ACME News, that is called an "issue". As in, issue 1, issue 2, issue 3, etc.
However, for a given day, they might publish several slightly different "versions" of issue 1. For example, the "initial version", the "updated version" and the "final version". I have seen these referred to as "editions", especially as in "final edition".
Is "edition" the right terminology for different "versions" of an issue? Where they have maybe corrected typos, added small updates to existing stories, but don't make any major changes until the next "issue" (which will have a entirely different set of news)?
The problem I have with "edition" is that it seems to overlap with other concepts, such as "Sunday edition" (which should be "Sunday issue" if you ask me), or "British edition", "American edition", "Canadian edition", etc. I don't want to use the word "edition" to refer to more than one concept, to avoid confusion.
So, are different versions of the same issue called "editions", period? Or can they be called "versions"? I'd like to stick fairly closely to established conventions for this.
