Heads up if your site is upgrading from XPP 8.4 to XPP 9.1 and uses xppcompare to automate the tracing of editorial traces between different versions of documents.
Publishers in the tax, legal, mil-spec, financial, pharmaceutical and a couple of other subject areas publish documents with change bars and revision markup to show what has changed between versions of a document.
So, if you publish some of this stuff, and if you use xppcompare, put some extra time in your release schedule to check out how the new, upgraded xppcompare process works in your environment. It will probably work pretty good, but do be sure to plan check it out.
There are changes to the comparator and the “.dxp pipeline”, which, in basic terms, is a set of transformations and java jars that prep and tweak the files during the compare process. These are very useful! But if you have customized them, you may need to adjust them post upgrade.
Also, you may want to adjust your batch workflow code to fire the new command line option that lets you say that you want to run the older or newer comparator.
Basically, all is manageable, but do plan some extra time to evaluate and, if needed, tweak your code for the comparison phase of XPP processing.
Hopefully, this will help save some kindred site out a bit of time.
