I've uploaded my addon (autorun reminder) and have been able to update it a few times. I see other addons in curse with revision numbers. How do I go about showing the revision number of my updated addon?
The authors of those addons simply used the revision number as the version string, whereas you entered "AutoRun_Reminder" as your version string and named your ZIP file "AutoRun_ReminderV2_5.zip".
I'm pretty sure it even tells you on the "Upload file" page that the version string should not include the name of your addon, only the actual version number you want to use, but if not, there you go. Just enter "v2.5" or "r72" or whatever you want users to see as the version number in that box.
Also, ZIP filenames can include periods, so "AutoRun_Reminder-v2.5.zip" would work too.
I just figured it out after studying other addon file names. You're right, just change the name of the upload file. I was under the mistaken impression that the file name had to be the name of the addon.
