Have you noticed that the edit window / grace period has changed? In the past I could fix typos and such within a few minutes and my post would not show a “1” revision history. Now it seems to do so pretty much immediately.
I noticed the same sometime last week. Looks like a change from the last Discourse upgrade. Shouldn’t be a problem… users can’t see your edit history. It’s just a notice that an edit occurred, by you or a moderator.
This is a change we made we made recently because some important edits were not being captured in the version history, making it hard for us to track changes made between mods. As @Seapup notes, it should not affect you other than seeing the little number by the pencil increase.
Well, if you are a prolific error generator like myself you edit a lot of your own posts. I believe there is a 30-edit limit per day? With the counter counting every edit, I can now do that in about 6 posts, lol.
I do create most in a word processor now, but I still edit them a lot.
Edit: Corrected the number of edits. So editing right away, lol.
