+ ~~~~~~~~~~~~~~~~~~
+ 
++* **BACKWARDS INCOMPATIBLE:** Loading a PKCS7 with no content field using
++  :func:`~cryptography.hazmat.primitives.serialization.pkcs7.load_pem_pkcs7_certificates`
++  or
++  :func:`~cryptography.hazmat.primitives.serialization.pkcs7.load_der_pkcs7_certificates`
++  will now raise a ``ValueError`` rather than return an empty list.
+ * **SECURITY ISSUE:** Fixed a bug where certain sequences of ``update()`` calls
+   when symmetrically encrypting very large payloads (>2GB) could result in an
+   integer overflow, leading to buffer overflows. *CVE-2020-36242*
