C++11

C++11 (formerly known as C++0x) is the most recent iteration of the C++ programming language. It was approved by ISO on 12 August 2011, replacing C++03. The name is derived from the tradition of naming language versions by the year of the specification's publication.
C++11 includes several additions to the core language and extends the C++ standard library, incorporating most of the C++ Technical Report 1 (TR1) libraries — with the exception of the library of mathematical special functions. C++11 was published as ISO/IEC 14882:2011in September 2011 and is available for a fee. The working draft most similar to the published C++11 standard is N3337, dated 12 January 2012; it has only editorial corrections from the C++11 standard.
