[boost] [geometry] Planning switch to C++11

Hi, We are planning to switch Boost.Geometry to C++11 https://github.com/boostorg/geometry/issues/590 Is the following procedure sensible: 1. Warn users on the Boost mailing lists about the planned switch to C++11 2. Make the switch (update the codebase) 3. Release the Boost.Geometry as C++11 e.g. with Boost 1.75 4. Announce on the Boost mailing lists that Boost.Geometry requires C++11 Are there any recommendations or requirements on how we should proceed?
