It would be very helpful if ExL included a Differences report (.diff file) for the Delivery-System-Skin mashup CSS file (mashupnew.css) and also any Letter-template XSLT files which have changed for each new Alma Release, and to post them alongside the Knowledge Base article for the release (ie. https://knowledge.exlibrisgroup.com/Alma/ReleaseNotes/00992017/May2017 ).

Any institution which has made local customizations based on these files needs to perform a manual review each month. While this isn't so horrific for the single mashup_new.css file, it is for the Letter-templates. Having a section which lists the differences would be a huge time-saver. Bonus points for a human readable explanation of the change.
