ABSTRACT
There is a perceived push towards memory-safe languages in the developer community. Various administrative bodies want to see a reduction in avoidable vulnerabilities in commonly used software. These vulnerabilities may cause harm of people, equipment, and property.

Long-term efforts in the standardization of C++ look like to become available in C++26. There is a wide range of proposals to improve the language, and merging them into the international standard is of utmost priority to the C++ committee.

We will look at those proposals, their current status in the upcoming C++26 standard, and the potential impact on the ecosystem and the development landscape. [...]
