C++26
The next-generation C++ language standard being developed by the C++ Standards Committee, expected to be officially published in 2026. It introduces major features including static reflection, pattern matching, and an executor/sender-receiver concurrency model.
Timeline (last 90 days)
The C++ standards committee is introducing a brand-new <debugging> header for C++26.
After using <debugging>, cross-platform projects no longer need to write conditionally compiled debugging code for different operating systems.
C++26 has not yet been officially released, and compiler support will take time.
C++26 introduces the Contracts feature, allowing developers to declare preconditions and postconditions directly on function interfaces.
In C++26 Contracts semantics, the handling modes for contract violations include ignoring, continuing execution after only logging diagnostics, and terminating directly.
The community's assessments of C++26 Contracts differ: some developers believe the unified contract syntax ends the chaos of three coexisting systems—assert, custom macros and documentation comments—while others worry that divergence in default behavior will lead to semantic inconsistency.
