I am not sure only because I have not tested it myself personally yet.
I was going to do so tonight but I had to finish other projects first.
But..."on paper" (per the read me version update notes) it "should" work. The notes say the crossbow mod is now using detection to be sure the player is not using a normal bow.
However, I still have some concerns with the way that script disables and enables attack (and other) controls when the player is using a crossbow. This could have adverse effects on some of the features in Combat Archery.
I do crossbow detection already in my mod to turn off SOME features such as draw the bow rate. If my crossbow detection works as intended I can release a new version that will stop my scripts from working anytime the player is using the cross bow. But then this would mean all the features of my mod (such as breathing sway and shots missed and critical shots) would be turned off when using a crossbow.
I will know more when I get a chance to test all this myself.
Is this still incompatible with crossbows of cyrodiil which just got an update?
