1. xml2-config now has a --dynamic option that can be used with --libs. This should always be used when linking dynamically (as we almost always are). With this flag available you don't have to switch to pkg-config to avoid overlinking.
2. Along with the new upstream version, I added a patch to hide the icu C++ API when not using C++11 or newer. That means dependents aren't forced to use C++11 when they're just trying to use libxml2's C API and don't even use icu. So if you added a C++11 requirement to any ports purely because of build failures in icu headers via libxml2, you can revert that now. - Josh
