+* The :mod:`ssl` module now rejects TLS certificate chains that contain one
+  of a set of compromised eMudhra intermediate CA certificates.  The affected
+  certificates are identified by their public key, so cross-signed copies that
+  reuse the same key are blocked as well.  It is a defense-in-depth backstop
+  that applies even when an application supplies its own root CA bundle, and
+  regardless of whether the platform trust store has removed trust.
