+  o Removed features:
+
+    - Remove support for clients claiming to support any standard
+      ciphersuites that we can actually provide.  (As of modern
+      OpenSSL versions, it's not necessary to fake any standard
+      ciphersuite, and doing so prevents us from using better
+      ciphersuites in the future, since servers can't know whether an
+      advertised ciphersuite is really supported or not.)  Some
+      hosts--notably, ones with very old versions of OpenSSL or where
+      OpenSSL has been built with ECC disabled-- will stand out
+      because of this change; TBB users should not be affected.
+      This implements the client side of proposal 198.
