+Synapse 1.30.1 (2021-03-26)
+===========================
+
+This release is identical to Synapse 1.30.0, with the exception of explicitly
+setting a minimum version of Python's Cryptography library to ensure that users
+of Synapse are protected from the recent [OpenSSL security advisories](https://mta.openssl.org/pipermail/openssl-announce/2021-March/000198.html),
+especially CVE-2021-3449.
+
+Note that Cryptography defaults to bundling its own statically linked copy of
+OpenSSL, which means that you may not be protected by your operating system's
+security updates.
+
+It's also worth noting that Cryptography no longer supports Python 3.5, so
+admins deploying to older environments may not be protected against this or
+future vulnerabilities. Synapse will be dropping support for Python 3.5 at the
+end of March.
+
+
+Updates to the Docker image
+---------------------------
+
+- Ensure that the docker container has up to date versions of openssl. ([\#9697](https://github.com/matrix-org/synapse/issues/9697))
+
+
+Internal Changes
+----------------
+
+- Enforce that `cryptography` dependency is up to date to ensure it has the most recent openssl patches. ([\#9697](https://github.com/matrix-org/synapse/issues/9697))
