The C++17 standard is feature complete and has been proposed for standardization. In compilers with experimental support for these features, it is usually referred to as C++1z.

Language Extensions

• Fold Expressions
• declaring non-type template arguments with auto
• Guaranteed copy elision
• Template parameter deduction for constructors
• Structured bindings
• Compact nested namespaces
• New attributes: [[fallthrough]], [[nodiscard]], [[maybe_unused]]
• Default message for static_assert
• Initializers in if and switch
• Inline variables
• if constexpr
• Order of expression evaluation guarantees
• Dynamic memory allocation for over-aligned data

Library Extensions

• std::optional
• std::variant
• std::string_view
• merge() and extract() for associative containers
• A file system library with the <filesystem> header.
• Parallel versions of most of the standard algorithms (in the <algorithm> header).
• Addition of mathematical special functions in the <cmath> header.
• Moving nodes between map<>, unordered_map<>, set<>, and unordered_set<>
