When is it time to call it a new edition?

[pmmg]

At what point do you feel you've made enough changes to a story, after its been published, that you ought to uptick the edition number? What is your threshold?

The first time around, the edits were so severe - several per page, plus plot fixes - that I deleted the old books and released new ones. (Twice.)

This last time around, as it was mostly trivial grammar bugs (1-2 per 8-10 pages), I just updated the interior. (No new edition.)

On my first novel, I published the e-book too quickly and noticed some formatting issues and a small but embarrassing continuity howler in the published text. I re-published it and made sure that the paperback was correct. The corrected e-book and paperback were marked as edition 1.1. A year later (last year) I made two very small textual changes to the story (one being a typo correction) and some modifications/additions to the editorial matter (especially the insertion of a guide to the characters, which several reviewers/readers had demanded. So that was the "second edition."
