C++ 23, the next major upgrade to the widely-used programming language, has been declared feature-complete. This means that the planned features for C++ 23, including support for standard library modules, have been finalized and are now ready for implementation. However, this doesn’t mean that development stops here. C++ 26 is already on the horizon, promising even more improvements and new capabilities.
In C++ 23, several features have been refined and added. These include static operator[], allowing for static access to elements of arrays and constexpr functions, providing compile-time evaluation and optimization. Safe range-based for loops have also been introduced, making it easier and safer to iterate over collections. Updates to std::print, the standard printing mechanism, have been made to enhance its usability and flexibility. Another notable addition is the monadic interface for std::expected, a type that represents either expected success or failure.
Looking ahead to C++ 26, developers can expect further enhancements. Improvements to aggregates will come in the form of std::get and std::tuple_size, allowing for easier manipulation and extraction of data from aggregate types. The #embed preprocessor directive will enable the embedding of external files directly into source code, streamlining the development process. With the inclusion of obtaining std::stacktrace from exceptions, debugging and error handling will become more efficient. Additionally, stackful coroutines will be introduced, offering a new approach to managing concurrent and parallel tasks.
With C++ 23 feature-complete and C++ 26 in the pipeline, the future of C++ looks bright. These upcoming releases will undoubtedly bring significant improvements and new possibilities to developers, ensuring that the programming language remains at the forefront of modern software development.

C++ 23 and C++ 26: The Future of the Programming Language

The most important thing for now is not C++ 26 or C++ 23, it should be the implementation for module.
