+# Synapse 1.113.0rc1 (2024-08-06)
+
+### Features
+
+- Track which rooms have been sent to clients in the experimental [MSC3575](https://github.com/matrix-org/matrix-spec-proposals/pull/3575) Sliding Sync `/sync` endpoint. ([\#17447](https://github.com/element-hq/synapse/issues/17447))
+- Add Account Data extension support to experimental [MSC3575](https://github.com/matrix-org/matrix-spec-proposals/pull/3575) Sliding Sync `/sync` endpoint. ([\#17477](https://github.com/element-hq/synapse/issues/17477))
+- Add receipts extension support to experimental [MSC3575](https://github.com/matrix-org/matrix-spec-proposals/pull/3575) Sliding Sync `/sync` endpoint. ([\#17489](https://github.com/element-hq/synapse/issues/17489))
+- Add typing notification extension support to experimental [MSC3575](https://github.com/matrix-org/matrix-spec-proposals/pull/3575) Sliding Sync `/sync` endpoint. ([\#17505](https://github.com/element-hq/synapse/issues/17505))
+
+### Bugfixes
+
+- Update experimental [MSC3575](https://github.com/matrix-org/matrix-spec-proposals/pull/3575) Sliding Sync `/sync` endpoint to handle invite/knock rooms when filtering. ([\#17450](https://github.com/element-hq/synapse/issues/17450))
+- Fix a bug introduced in v1.110.0 which caused `/keys/query` to return incomplete results, leading to high network activity and CPU usage on Matrix clients. ([\#17499](https://github.com/element-hq/synapse/issues/17499))
+
+### Improved Documentation
+
+- Update the [`allowed_local_3pids`](https://element-hq.github.io/synapse/v1.112/usage/configuration/config_documentation.html#allowed_local_3pids) config option's msisdn address to a working example. ([\#17476](https://github.com/element-hq/synapse/issues/17476))
+
+### Internal Changes
+
+- Change sliding sync to use their own token format in preparation for storing per-connection state. ([\#17452](https://github.com/element-hq/synapse/issues/17452))
+- Ensure we don't send down negative `bump_stamp` in experimental sliding sync endpoint. ([\#17478](https://github.com/element-hq/synapse/issues/17478))
+- Do not send down empty room entries down experimental sliding sync endpoint. ([\#17479](https://github.com/element-hq/synapse/issues/17479))
+- Refactor Sliding Sync tests to better utilize the `SlidingSyncBase`. ([\#17481](https://github.com/element-hq/synapse/issues/17481), [\#17482](https://github.com/element-hq/synapse/issues/17482))
+- Add some opentracing tags and logging to the experimental sliding sync implementation. ([\#17501](https://github.com/element-hq/synapse/issues/17501))
+- Split and move Sliding Sync tests so we have some more sane test file sizes. ([\#17504](https://github.com/element-hq/synapse/issues/17504))
+- Update the `limited` field description in the Sliding Sync response to accurately describe what it actually represents. ([\#17507](https://github.com/element-hq/synapse/issues/17507))
+- Easier to understand `timeline` assertions in Sliding Sync tests. ([\#17511](https://github.com/element-hq/synapse/issues/17511))
+- Reset the sliding sync connection if we don't recognize the per-connection state position. ([\#17529](https://github.com/element-hq/synapse/issues/17529))
+
+
+
