The only time a version # needs to be changed is when the script changes. If there are no changes in the script then it doesn't check the version number. That way it only requires you to upload scripts that have changed and not all of them.
When we put out the 7.5.4.2 release, I didn't update all of the scripts since it was just a once script change.
On the initial bug in this report, my fault. I only had 1 subscription to test with on my devel site, so I had set it to 1 per page
