The C++20 Firehose Talk
summary
Claims: format faster than printf with extensible, efficient formatting into buffers; char8_t for UTF-8 as a distinct, overloadable character type; a calendar/timezone library (chrono extensions) arrives; ranges lazy iota view plus views (filter/transform/join/split) and some range helpers postponed to C++23; source_location replaces many macros; concepts constrain templates but do not check every internal use; coroutines exist as language feature while higher‑level libraries and executors remain work in progress; threads gain stop_token cancellation and joining helpers; bit_cast, span, atomics, modules, consteval/constexpr improvements all land.
