The draft for the upcoming C++26 standard reached completion, Herb Sutter announced on Hacker News. Among the headline features are compile‑time reflection, memory‑safety extensions, contract syntax, and a unified async model built around std::execution. Reflection lets code describe and generate itself without runtime cost, opening a new path for metaprogramming libraries and will soon be visible in production toolchains.

Reflection also powers cppfront, a prototype front‑end that translates interface syntax into pure ISO C++. The draft adds contracts with pre‑ and post‑conditions, exposing them to callers and static analysers, and replaces the C assert macro with a native statement. Memory safety upgrades automatically eliminate undefined reads and add bounds checks to vectors, strings and spans, proven at scale by Google and Apple and prevented crashes.

Concurrency receives a fresh abstraction layer via std::execution, defining schedulers, senders and receivers that compose into customizable asynchronous algorithms and interoperate with C++20 coroutines. GCC and Clang have already integrated most of these components, positioning the language to ship these capabilities in the next mainline releases. Developers can now adopt safer, more expressive code without extensive rewrites.
