This page shows the C++11 features that are added by each version of GCC, in case you're curious how C++11 support has changed from 4.7 to 4.8: http://gcc.gnu.org/projects/cxx0x.html http://gcc.gnu.org/projects/cxx0x.html EDIT: I see that some of the C++11 changes are also listed on the change log (http://gcc.gnu.org/gcc-4.8/changes.html http://gcc.gnu.org/gcc-4.8/changes.html), but that page seems to be missing the changes in concurrency support: bidirectional fences, memory model, `at_quick_exit`, and thread-local storage.
