C++14 is the fastest turnaround time in history for a new standard of C++ with being approved by the ISO C++ committee. While everyone signed off on the C++14 draft standard, there's editorial tweaks, various fixes, etc, to take before officially shipping International Standard ISO/IEC 14882:2014(E) Programming Language C++ -- the C++14 standard.
Confirmation of C++14 being done was made to the ISOCPP.org site.
C++14 is just an incremental update over C++11 with some new features like function return type deduction, variable templates, binary literals, generic lambdas, etc. More of the C++14 features are listed on Wikipedia. Stay tuned for the official C++14 specification release later in the year.
