The ISO C++ committee recently concluded its meeting in Hagenberg, Austria, marking a significant milestone for C++26 development. At this gathering, the committee finalized the feature freeze for the upcoming C++26 standard.
Key highlights from the meeting include:
Approval of major C++26 features like contracts, reflection, and concurrent queues
Progress on safety and security improvements through profiles and library hardening
Advancements in SIMD, linear algebra, and other core language capabilities
Discussions on potential C++29 features like pattern matching
The committee made important decisions on which features will be included in C++26, setting the stage for the next phase of refining and implementing those features. There was also forward-looking discussion on the roadmap for C++29 and beyond.
With the feature freeze complete, the focus now shifts to finalizing the technical details and wording for C++26 ahead of the planned release in 2026. The next meeting in Sofia, Bulgaria will be crucial for resolving any remaining issues.
What are your thoughts on the direction C++26 is taking based on these updates? Are there any features you’re particularly excited about or wish had made the cut?
I’ve been using C++ professionally for over a decade, and I’m cautiously optimistic about C++26. The addition of contracts is long overdue - it’ll save countless hours of debugging and make our codebases more robust. I’ve had to implement my own contract-like system in previous projects, so having it baked into the language is a huge win.
Reflection is intriguing, but I’m reserving judgment until I see how it performs in real-world scenarios. In theory, it could simplify a lot of boilerplate code, especially in serialization and ORM layers. However, I’ve seen similar features in other languages lead to some pretty gnarly code when overused.
The emphasis on security is crucial, especially for those of us working in industries with strict compliance requirements. I’m hopeful that the new profiles will make it easier to write secure code by default, rather than having to bolt on security measures after the fact.
While the feature set looks promising, I’m a bit concerned about the growing complexity of the language. Each new feature increases the cognitive load on developers, especially those new to C++. I hope the committee is considering ways to manage this complexity growth in future standards.
As someone who’s been following C++ evolution closely, I’m quite pleased with the direction C++26 is taking. The inclusion of contracts is a game-changer for code reliability and maintainability. I’ve been burned too many times by subtle bugs that could have been caught with proper preconditions and postconditions.
Reflection is another feature I’m eagerly anticipating. It’ll open up so many possibilities for metaprogramming and generic code. I’ve worked on projects where we had to resort to convoluted template metaprogramming or external code generation tools to achieve what reflection will make trivial.
The focus on safety and security is also commendable. In today’s threat landscape, we can’t afford to ignore these aspects. I’m curious to see how the proposed profiles will be implemented and adopted by the community.
One thing I’m slightly disappointed about is the absence of pattern matching in C++26. It would have been a powerful addition to the language. However, I understand the need to prioritize and not overload a single release with too many major features. Looking forward to seeing how it shapes up for C++29.
excited about contracts! been waitin for ages. reflection sounds cool too, but gotta see how it works irl. kinda bummed pattern matching didnt make it but hey, c++29 maybe?
safety stuff is good i guess. hope it doesnt slow down compile times tho. overall, c++26 lookin pretty solid!
but hey, c++29 maybe?
