Hi,
I have not been consequent with writing which files have changed in the changelog, but in general, new versions of DFFS involve the JS and CSS files for DFFS – and any plugin that is mentioned in the changelog.
If you have a relatively new DFFS install, you shouldn’t have to change the CEWP codes – only replace the files in the “SPJS/DFFS” folder.
Hope this helps,
Alexander
