MVE 3.0.4 to 3.0.5 upgrade issues

Has anyone experienced negative issues upon installing the MVE 3.0.4 to 3.0.5 upgrade yet?

Is this upgrade worth potentially having to FIX all of my installed Add-ons?

Has the upgrading system evolved enough so that existing “My Changes Add-ons” are not affected?

sigh…growning tired of spending time doing updates, thought i bought a ‘finished’ product…““sad face””
