In June 2025, Hoxnox developed ABI version 2 support for opentelemetry-cpp within the conan-io/conan-center-index repository. By introducing a new with_abi_v2 option in conanfile.py, Hoxnox enabled downstream projects to opt into ABI v2, addressing compatibility with newer opentelemetry-cpp releases and reducing build issues. The implementation required careful configuration of CMake variables to ensure correct build behavior when ABI v2 is selected. This work leveraged skills in C++, build systems, and package management, and was delivered as a single, traceable commit. The focused contribution provided a clear upgrade path for users needing ABI v2 compatibility in their projects.
