GCC 5 uses the new C++ ABI by default. When building new code, you might run
into link time errors like:
...: undefined reference to '_ZNSt6chrono12steady_clock3nowEv@GLIBCXX_3.4.17'
Or you might see linkage failures with "std::__cxx11::string" in the output.
These are signs that you need to rebuild packages using the new C++ ABI.
You can quickly do so by using revdep-rebuild like so:
# revdep-rebuild --library 'libstdc\+\+\.so\.6'

i know there's no rush, but let's not loose sight of this.
