Since ConfiForms app version 2.x we publish release notes here 

Version 2.26.5

• Move/Copy attachments will be still possible on pages that have ConfiForms forms and want to move/copy attachments from the same page even when the user does not have view permissions on the ConfiForms page (when the form is set to "allow reads" parameter, overriding explicitly Confluence page permissions model) 

Version 2.26.4

• Rendering: Fixed issue with accessing properties of the field when it is referenced through the smart field
• Rollback of "move attachment" IFTTT change due to incomplete implementation of possible user scenarious. Making it look broken when an attachment that is moved remains referenced in some field of a ConfiForms form
