Current status

 

C++14 is a minor version after the major version C++11, featuring mainly minor improvements and defect fixes. Its approval was announced on August 18, 2014. It was released on December 15, 2014.

Before its approval, C++1y is sometimes used to indicate its release in 2010s.

New language features

• variable templates
• generic lambdas
• lambda init-capture
• new/delete elision
• relaxed restrictions on constexpr functions
• binary literals
• digit separators
• return type deduction for functions
• aggregate classes with default non-static member initializers.

New library features

• std::make_unique
• std::shared_timed_mutex and std::shared_lock
• std::integer_sequence
• std::exchange
• std::quoted
• and many small improvements to existing library facilities, such as
  • two-range overloads for some algorithms
  • type alias versions of type traits
  • user-defined literals for basic_string, duration and complex
  • etc.
