Here’s a list of the Eventcache (changelog) EventType codes and their meanings. This list is from Wss3.0 (SharePoint 2007, MOSS) but still relevant in the main for later versions.
Mostly here as a reference for me as I am continually looking this stuff up and having to perform the conversion in Excel!
Enjoy!
