Different version numbering scheme, lower main number - not updating

Damn…
I uploaded the first version of my WebExtension with the version number “1” (I thought maybe I’d like to use it as a build number) - I paid it no mind and had soon forgotten all about it.

Now I thought it would be nicer if I changed to naming it with 3 places (making the first version more like a 0.1.0, which would better reflect the state of it).
So I uploaded my first update to it as 0.1.1 (small fixes). But, alas, now I don’t see an update in Add-ons Manager.

Do I have to use a version with a leading 1 or greater now? Is there a way to change it, or to push the lower number over the older version?

The version numbering works as such that 0.1.1 is smaller than 1.0.0 so the users will not be updated with a lower version.

All new uploads must have a higher version number.

Aw, too bad. I thought there was a way to “re-define” the current version.
Thanks for the answer!
