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))
