History of C++
 Early C++
- 1979: C with Classes first implemented
- New features: classes, member functions, derived classes, separate compilation, public and private access control, friends, type checking of function arguments, default arguments, inline functions, overloaded assignment operator, constructors, destructors, f() same as f(void), call-function and return-function (synchronization features, not in C++)
- Libraries: the concurrent task library (not in C++)
- 1982: C with Classes reference manual published
- 1984: C84 implemented, reference manual published
- 1985: Cfront 1.0
- New features: virtual functions, function and operator overloading, references, new and delete operators, the keyword const, scope resolution operator
- Library additions: complex, string, iostream
- 1985: The C++ Programming Language, 1st edition
- 1987: C++ support in GCC 1.15.3
- 1989: Cfront 2.0
- New features: multiple inheritance, pointers to members, protected access, type-safe linkage, abstract classes, static and const member functions, class-specific new and delete
- Library additions: I/O manipulators
- 1990: The Annotated C++ Reference Manual
This book described the language as designed, including some features that were not yet implemented. It served as the de-facto standard until the ISO.
- New features: namespaces, exception handling, nested classes
- 1991: Cfront 3.0
- 1991: The C++ Programming Language, 2nd edition
 Standard C++
- 1990 ANSI C++ Committee founded
- 1991 ISO C++ Committee founded
- 1992 STL implemented in C++
- New features: RTTI (dynamic_cast, typeid), covariant return types, cast operators, mutable, bool, declarations in conditions, template instantiations, member templates, export
- Library additions: containers, algorithms, iterators, function objects (based on STL), locales, bitset, valarray, auto_ptr, templatized string, iostream, and complex.
- 1998 The C++ Programming Language, 3rd edition
- 1999 Boost founded by the committee members to produce new high-quality candidate libraries for the standard.
This was a minor revision, intended to be little more than a technical corrigendum
- New features: value initialization
- 2006 Performance TR (ISO/IEC TR 18015:2006) (ISO Store) (2006 draft)
- 2007 Library extension TR1 (ISO/IEC TR 19768:2007) (ISO store) (2005 draft).
This TR is a C++ library extension, which adds the following to the C++ standard library:
- From Boost: Reference wrapper, Smart pointers, Member function, Result Of, Bind, Function, Type Traits, Random, Mathematical Special Functions, Tuple, Array, Unordered Containers (including Hash), and Regular Expressions.
- From C99: mathematical functions from math.h that were new in C99, blank character class, Floating-point environment, hexfloat I/O Manipulator, fixed-size integral types, the long long type, va_copy, the snprintf() and vfscanf() families of functions, and the C99 conversion specifies for printf() and scanf() families of functions.
All of TR1 except for the special functions was included in C++11, with minor changes.
- 2010 Mathematical special functions TR (ISO/IEC 29124:2010) (ISO Store) (2010 draft)
This TR is a C++ standard library extension, which adds the special functions that were part of TR1, but were not included in C++11: elliptic integrals, exponential integral, Laguerre polynomials, Legendre polynomials, Hermite polynomials, Bessel functions, Newmann functions, beta function, and Riemann zeta function.
C++11(ISO/IEC 14882:2011) (ISO Store) (ANSI Store) (Post-publication draft).
A large number of changes were introduced to both standardize existing practices and improve the abstractions available to the C++ programmers
- New language features: auto and decltype, defaulted and deleted functions, final and override, trailing return type, rvalue references, move constructors/move assignment, scoped enums, constexpr and literal types, list initialization, delegating and inherited constructors, brace-or-equal initializers, nullptr, long long, char16_t and char32_t, type aliases, variadic templates, generalized unions, generalized PODs, Unicode string literals, user-defined literals, attributes, lambda expressions, noexcept, alignof and alignas, multithreaded memory model, thread-local storage, GC interface, range for (based on a Boost library), static assertions (based on a Boost library)
- New library features: atomic operations library, emplace() and other use of rvalue references throughout all parts of the existing library, std::initializer_list, stateful and scoped allocators, forward_list, chrono library, ratio library, new algorithms, Unicode conversion facets
- From TR1: all of TR1 except Special Functions.
- From Boost: The thread library, exception_ptr, error_code and error_condition, iterator improvements (std::begin, std::end, std::next, std::prev)
- From C: C-style Unicode conversion functions
- 2011 Decimal floating-point TR (ISO/IEC TR 24733:2011) (ISO Store) (2009 draft)
This TR implements the decimal floating-point types from IEEE 754-2008 Standard for Floating-Point Arithmetic: std::decimal::decimal32, std::decimal::decimal64, and std::decimal::decimal128.
- 2012 The Standard C++ Foundation founded
- 2013 The C++ Programming Language, 4th edition
C++14(ISO Store) (2014 final draft)
Minor revision of the C++ standard
- New language features: variable templates, polymorphic lambdas, lambda captures expressions, new/delete elision, relaxed restrictions on constexpr functions, binary literals, digit separators, return type deduction for functions, aggregate initialization for classes with brace-or-equal 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 string, duration, and complex number literals, etc.
- 2015 Filesystem library TS (ISO/IEC TS 18822:2015) (ISO Store) (2014 draft)
This TS is an experimental C++ library extension that specifies a filesystem library based on boost.filesystem V3 (with some modifications and extensions)
- 2015 Extensions for Parallelism TS (ISO/IEC TS 19570:2015) (ISO Store) (2015 draft)
This TS standardizes parallel and vector-parallel API for all standard library algorithms, as well as adds new algorithms such as
- 2015 Extensions for Transactional Memory TS (ISO/IEC TS 19841:2015) (ISO Store) (2015 draft)
This TS extends the C++ core language with synchronized and atomic blocks, as well as transaction-safe functions, which implement transactional memory semantics.
- 2015 Extensions for Library Fundamentals TS (ISO/IEC TS 19568:2015) (ISO Store) (2015 draft)
This TS adds several new components to the C++ standard library: optional, any, string_view, sample, search, apply, polymorphic allocators, and variable templates for type traits.
- 2015 Extensions for Concepts TS (ISO/IEC TS 19217:2015) (ISO Store) (2015 draft)
This TS extends the C++ core language with concepts (named type requirements) and constraints (limits on the types allowed in template, function, and variable declarations), which aids metaprogramming and simplifies template instantiation diagnostics, see concepts
 Future development
- Experimental technical specifications (Concurrency, Networking, Ranges, Modules, Numerics)
- 2017 C++17 (2015-11-09 draft)
The next major revision of the C++ standard
- Language changes: fold-expressions, u8-char, simplified nested namespaces, made noexcept part of type system, __has_include. Removed trigraphs, the register keyword, bool increment
- Library changes: contiguous iterators, non-member size/empty/data, try_emplace, insert_or_assign, uncaught_exceptions, variadic lock_guard, as_const, conjunction/disjunction/negation, type trait variables, transparent owner_less, rounding functions for duration and time_point. Removed auto_ptr, the deprecated function objects, the obsolete iostreams aliases.
