Command line tool changes but those are captured in shell files we supply. The AccessControl interfaces move but I don’t expect deployers would have directly interacted with that service as an API. Various beans move but they’re system-defined in almost all cases. Biggest API ripple is the IdentifierGenerationStrategy stuff, but that’s unlikely to affect anybody but us and probably needs more work given the use of impl classes all over the code base.
Moved net.shibboleth.utilities.java.support.xml → net.shibboleth.shared.xml
Moved BasicParserPool and an errorhandler class into an impl subpackage. Lots of Java code will have used the various XSupport classes and likely depend on the ParserPool and exception classes, but I do not expect deployer impact of much significance.
