In the old days, we used to be able to submit a version of an addon with an “a” or “b” character in the version string, in order to sign an addon for dev/debugging purposes without it appearing as the listed addon or users being automatically updated to that version. This was very convenient when working with users in trying to debug problems that were not easily reproduce-able. But when trying this approach (using alpha/beta flag in the version string), I find this is no longer the case.
Is there other recourse that can be done in order to accomplish this, other than submitting it under another addon id and self-signing/self-hosting it?
