@DrChiper My reply was more on a humor tone that any things. Truly, the subject is half serious, don't mind it.

@BetterRed Hence the advantage of the semantice with four number for randomly shared version of a plugin. That mark it in the changelog that the user use a non standard version. Obviously, is even better that user that originaly share the hacky version delete it after their usage is ended, but second adavantage of four number version: Their don't interfer with official one that can take priorité of any hacky version that the user had installed.

@kovidgoyal Agree. 4 version numbers is just temporary version, preview, test, edit suggestion, etc. It work fine but it also inherently instable and unsuported. At the end, a official version with only 3 number need to be release and that the only one that we need to take care, even if it maintain by the community.
Pratical example: Right now, a user curently report a bug with my plugin, and I share a 4 version numbers to see if I corretly identifier and fix the bug their enconter before deploy the official one with only 3 numbers version.

@kiwidude Probably your own Quality Check plugin thread, wich one a user share a fix version for Calibre 8.12, but had not changed the number version of his mod, creating a risk of misidentify if is a official version instaled or the altred one in any future bug report.
Also, to clarify, for me a "official" version is the one in the attached to the first post, regardless of if is the orignal author or a maintener who build it, and so the only one that Calibre will search and use. See the others paragraphe/reply above.
