+- Update to 16.0.0:
+  * Changes:
+    +  Officially support Python 3.5.
+    +  service_identity.SubjectAltNameWarning is now raised if the server certicate lacks a proper SubjectAltName. [#9]
+    +  Add a __str__ method to VerificationError.
+    +  Port from characteristic to its spiritual successor attrs.
+  * Backward-incompatible changes:
+    +  Python 3.3 and 2.6 aren't supported anymore. They may work by chance but any effort to keep them working has ceased.
+    +  pyOpenSSL versions older than 0.14 are not tested anymore. They don't even build with recent OpenSSL versions.
+- Update spec file with new upstream package requirements.
