C++ 11, also catchily known as ISO/IEC 14882:2011, has been finalised and published by the International Organisation for Standardisation (ISO).
Having had its final draft approved by the ISO C++ committee way back in March, the standard has now been completed and ISO sees it fit to be published.
However, that doesn’t mean that you can get your C++11 compiler today. Most popular C++ compilers now include at least some functionality of C++11 – many include the new standard libraries for example, as that is relatively easy to implement. No current compiler includes all of C++11, and none is likely to until at least next year. However, all of the C++11 features have been implemented somewhere by someone, so if there are any implementation problems there is someone somewhere in the world that has a working compiler that can do it already.
C++11 has been designed to be a general programming language which includes systems programming support, which builds upon the foundations of C but provides better abstraction, object orientation support, and generic programming support. For example, C++11 includes a dizzying array of new abstraction mechanisms that should allow developers to work safely and efficiently with even more complex data types than were previously possible.
