Meeting C++ 2026 - Profiles are coming

Guy Davidson

On Day 3 at 0:00 (CET/Berlin) in Track A [Saphir Room and online]

"Profiles" are a framework designed to improve software safety and security by allowing developers to opt into specific sets of rules and guarantees. Championed by C++ creator Bjarne Stroustrup, they provide a way to transition existing codebases toward modern safety standards (like memory and type safety) without fragmenting the language into incompatible dialects.

A "profile" is a deterministic and portably enforceable subset of rules designed to achieve a specific guarantee. Unlike general compiler flags, profiles are intended to be part of the source code, allowing compilers and static analysis tools to verify that a program follows strict safety protocols.

This talk will gently introduce profiles, explain how they work, and address the obvious question of why you should use them.
