consumption. Conan client has a local cache for package storage, and so it allows you to fully create and test packages offline. You can also work offline as long as no new packages are needed from remote servers upgrade easier. 2.2 New graph model Conan 2 defines new requirement traits (headers, libs, build, run, test, package_id_mode, options, transitive_headers, transitive_libs) and package types (static, shared associated to recipes and packages. This feature can be very useful to manage build logs, tests executable, test results, coverage data and many other different files needed for traceability, compliance and business
