 ## Zulip 5.x series
 
+### 5.4 -- 2022-07-11
+
+- CVE-2022-31134: Exclude private file uploads from [exports of public
+  data](https://zulip.com/help/export-your-organization#export-of-public-data). We
+  would like to thank Antoine Benoist for bringing this issue to our
+  attention.
+- Upgraded python requirements.
+- Improved documentation for load balancers to mention CIDR address
+  ranges.
+- Documented an explicit list of supported CPU architectures.
+- Switched `html2text` to run as a subprocess, rather than a Python
+  module, as its GPL license is not compatible with Zulip’s.
+- Replaced `markdown-include` python module with a reimplementation,
+  as its GPL license is not compatible with Zulip’s.
+- Relicensed as GPL the `tools/check-thirdparty` developer tool which
+  verifies third-party licenses, due to a GPL dependency by way of
+  `python-debian`.
+- Closed a potential race condition in the Tornado server, with events
+  arriving at exactly the same time as request causing server errors.
+- Added a tool to help automate more of the release process.
