C++17 - cppreference.com

C++17 is a major version that follows the minor version C++14 and introduces new language and library features. The standard was published in December 2017.

The following features were merged into C++17:

• From the File System TS: the filesystem library.
• From the Library fundamentals v1 TS: features, including std::any, std::optional, std::string_view, std::apply, polymorphic allocators, searchers.
• From Library fundamentals v2 TS: std::void_t, std::conjunction, std::disjunction, std::negation, std::not_fn, std::gcd, std::lcm.
• From Parallelism v1 TS: features, including execution policies, std::reduce, std::inclusive_scan, std::exclusive_scan, but removing exception_list.
• From Mathematical special functions IS: mathematical special functions.
• From C11: std::aligned_alloc, std::timespec_get.

• std::auto_ptr,
• deprecated function objects,
• std::random_shuffle,
• std::unexpected,
• the obsolete iostreams aliases,
• trigraphs,
• the register keyword,
• bool increment,
• dynamic exception specification

• std::iterator,
• std::raw_storage_iterator,
• std::get_temporary_buffer,
• std::is_literal_type,
• std::result_of,
• all of <codecvt>

• u8 character literal
• made noexcept part of type system
• new order of evaluation rules
• lambda capture of *this

• constexpr

  compile-time if constexpr

  constexpr lambda

• Variables

  inline variables

  structured bindings

  initializers for if and switch

  guaranteed copy elision

  temporary materialization

• Templates

  fold-expressions ( ... )

  class template argument deduction tuple t(4, 3, 2.5)

  constant template parameters declared with auto

• Namespaces

  simplified nested namespaces

  using-declaration declaring multiple names

  attribute namespaces don't have to repeat

• As of 2020-11-20, the latest release of Oracle Developer Studio is 12.6. Its documentation does not mention C++17.
• Cray compiler may have support for some features earlier than 11.0. That version is when it became a derivative of Clang, gaining all of the attendant language feature support of the base compiler. See Cray/HPE document S-2179.
