The newest versions of the C++ standard are C++20 and C++23. C++20 was released in 2023 and is the current standard, but C++23 has been completed and is in its final stage of approval. C++20 replaced C++17 and has extensive changes. Currently, Microsoft's Visual C++ Redistributable only supports Windows systems, and there are plans to release more technical specifications for C++. There is also a newer version of C++, C++23, which is considered more advanced. In April 2023, the latest major version of the C++ compiler, GCC 13.1, was released.
