What happened and what to do
Published on May 28, 2026, Ou Changkun’s free, open-access book is a tutorial on modern C++ features, from C++11 to C++26, aimed at engineers. Its scope spans multiple language versions, providing a reference for understanding how C++ has evolved.
A company can use this overview to assess which C++ standards its systems rely on and plan upgrades safely. Practical work could include inventorying compilers and dependencies, adding automated tests, validating compatibility in continuous integration, and monitoring failures during migration—without updating code solely to follow the newest standard.
How the consultancy can help
Wendelmaques can diagnose compatibility and risks in a C++ codebase, define a modernization scope, and implement tests, automation, and monitoring. Operation and maintenance can be included according to the client’s needs.
