80  * Check for correct responses from the Version API for features or
81  * functionality not (yet) guaranteed by the current API version.
82  * If a feature is available, it is expected to conform to the API specification
83  * for the library Version::release(). As we discover features that break
84  * forward-compatibility of the API, we will have to provide developer documentation
85  * or sample code for build-time CMake feature checks.
86  *
87  * This is the test for pre-0.1 features leading up to that specification.
88  *
89  * \internal
90  * Designed but unimplemented features should be tested with ``EXPECT_FALSE``
91  * until they are implemented, then toggled to ``EXPECT_TRUE`` as implemented as
92  * extensions of the current API spec. (There aren't any yet.)
