Determine whether requested_version is satisfied by
current_version; in other words, current_version is >=
requested_version.
Parameters:
requested_version – version to check for compatibility
current_version – version to check against
same_major – if True, the major version must be identical between
requested_version and current_version. This is used when a
major-version difference indicates incompatibility between the two
versions. Since this is the common-case in practice, the default is
True.
