  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

  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.)
