Python 3.8 is now [end-of-life](https://devguide.python.org/versions/). As per our [Deprecation Policy for Platform Dependencies](https://element-hq.github.io/synapse/latest/deprecation_policy.html#policy), Synapse will be dropping support for Python 3.8 in the next release; Synapse 1.119.0. Synapse 1.118.x will be the final release to support Python 3.8. If you are running Synapse with Python 3.8, please upgrade before the 1.119.0 release, due in less than one month. On the other end of the spectrum, Synapse 1.118.0 is the first release to support [Python 3.13](https://www.python.org/downloads/release/python-3130/)! [PostgreSQL 17](https://www.postgresql.org/about/news/postgresql-17-released-2936/) is also supported as of this release. - Added the `display_name_claim` option to the JWT configuration.
