Hi Thomas -
I hear you and I would love to do that if I could. However, Apple won't let any developer have two versions of the same app in the app store at the same time. So we would have to release a completely separate app every time we did an update, which would be super confusing for our users (two different apps can't have the same name even). We do regression testing on all new releases to try to make sure we're not breaking older MIBs with the new changes—if you're seeing something that's not working, please let us know and we will take a look at it right away. We try to get patches out as soon as bugs are found and fixed, and we have a list of known bugs on the support home page under Releases. Also, you can always use the Simulator to roll back to a previous version as well - the link to that is in the same article in Releases.
