Further, Nginx and Haproxy, two common reverse proxies, do not appear to support configuring their upstreams to use HTTP pipelining and thus would not be affected. For both of these reasons, we consider it unlikely that a Synapse deployment would be set up in such a configuration. + +Despite that, we cannot rule out that some installations may exist with this unusual setup and so we are releasing this security update today. + +**pip users:** Note that by default, upgrading Synapse using pip will not automatically upgrade Twisted. **Please manually install the new version of Twisted** using `pip install Twisted==24.7.0rc1`. Note also that even the `--upgrade-strategy=eager` flag to `pip install -U matrix-synapse` will not upgrade Twisted to a patched version because it is only a release candidate at this time. + +### Internal Changes + +- Upgrade locked dependency on Twisted to 24.7.0rc1. ([\#17502](https://github.com/element-hq/synapse/issues/17502)) + + +# Synapse 1.112.0rc1 (2024-07-23) + +Please note that this release candidate does not include the security dependency update +included in version 1.111.1 as this version was released before 1.111.1. +The same security fix can be found in the full release of 1.112.0. + +### Features + +- Add to-device extension support to experimental [MSC3575](https://github.com/matrix-org/matrix-spec-proposals/pull/3575) Sliding Sync `/sync` endpoint.

([\#17434](https://github.com/element-hq/synapse/issues/17434)) +- Order `heroes` by `stream_ordering` as the Matrix specification states (applies to `/sync`).
