Thanks!
The configurations seems to be all right on both ends. After updating though, still the old script files were loaded – I assume the CDN has cached them heavily, as the local cache is clean.
After switching the script source back to the default minified everything seems to work all right. Make sure to clear the CDN cache after plugin updates or perhaps configure the CDN to consider query strings (not to ignore query string). With that the CDN will know when to refresh the scripts as the query string updates after a plugin update.
