CppCon 2026

The next evolution of C++ has officially arrived, bringing a massive wave of enhancements to both the core language and the Standard Library. But with hundreds of committee proposals officially baked into the standard, where do you start? Continuing the tradition from previous releases, this fast-paced session delivers a comprehensive look at the new and updated features that define C++26.

We won’t get bogged down in the minutiae of every single ISO proposal—covering everything in detail is impossible in just one hour. Instead, you'll get a high-level, curated overview of the most impactful changes, from the major game-changers down to the small quality-of-life gems. If you want to get up to speed with the new standard and see how it will shape your codebase, this session is for you.

The session will touch on the following core language and Standard Library topics.

C++26 core language changes include - Reflection - Contracts - Unnamed placeholder variables - = delete("reason"); - Pack indexing - #embed - constexpr exceptions, constexpr placement new - Variadic friends - ...

C++26 Standard Library changes include - Execution control library - New libraries such as , , , , , and more - std::inplace vector: dynamically-resizable vector with fixed capacity - std::philox engine: counter-based random number engine - std::text_encoding: text encodings identification - More constexpr for containers and container adaptors - Saturation arithmetic - New SI prefixes - Printing Blank Lines with std::println() - ...

Where applicable, I’ll point you toward other specialized CppCon sessions for those ready to dive even deeper into specific topics.
