    • Use markdown where necessary, mostly for code blocks.
    • End with either a period (.) or an exclamation mark (!).
    • Start with a capital letter.
    • Feel free to credit yourself, by adding a sentence "Contributed by @github_username." or "Contributed by [Your Name]." to the end of the entry.
  • Code style is correct (run the linters)

Other than this & the failing Complement (have put in a re-run but it looked slightly bizarre, it might come up red again), this seems good to me!

#### Features

- Add experimental support for the [MSC4370](matrix-org/matrix-spec-proposals#4370) Federation API `GET /extremities` endpoint. ([#&#8203;19314](element-hq/synapse#19314))
- [MSC4140: Cancellable delayed events](matrix-org/matrix-spec-proposals#4140): When persisting a delayed event to the timeline, include its `delay_id` in the event's `unsigned` section in `/sync` responses to the event sender. ([#&#8203;19479](element-hq/synapse#19479))
- Expose [MSC4354 Sticky Events](matrix-org/matrix-spec-proposals#4354) over the legacy (v3) /sync API. ([#&#8203;19487](element-hq/synapse#19487))
- When Matrix Authentication Service (MAS) integration is enabled, allow MAS to set the user locked status in Synapse. ([#&#8203;19554](element-hq/synapse#19554))

#### Bugfixes

- Fix `Build and push complement image` CI job pointing to non-existent image. ([#&#8203;19523](element-hq/synapse#19523))
- Fix a bug introduced in v1.26.0 that caused deactivated, erased users to not be removed from the user directory. ([#&#8203;19542](element-hq/synapse#19542))

#### Improved Documentation

- In the Admin API documentation, always express path parameters as `/<param>` instead of as `/$param`. ([#&#8203;19307](element-hq/synapse#19307))
- Update docs to clarify `outbound_federation_restricted_to` can also be used with the [Secure Border Gateway (SBG)](https://element.io/en/server-suite/secure-border-gateways). ([#&#8203;19517](element-hq/synapse#19517))
- Unify Complement developer docs. ([#&#8203;19518](element-hq/synapse#19518))

#### Internal Changes

- Put membership updates in a background resumable task when changing the avatar or the display name. ([#&#8203;19311](element-hq/synapse#19311))
- Add in-repo Complement test to sanity check Synapse version matches git checkout (testing what we think we are). ([#&#8203;19476](element-hq/synapse#19476))
- Migrate `dev` dependencies to [PEP 735](https://peps.python.org/pep-0735/) dependency groups. ([#&#8203;19490](element-hq/synapse#19490))
- Remove the optional `systemd-python` dependency and the `systemd` extra on the `synapse` package. ([#&#8203;19491](element-hq/synapse#19491))
- Avoid re-computing the event ID when cloning events. ([#&#8203;19527](element-hq/synapse#19527))
- Allow caching of the `/versions` and `/auth_metadata` public endpoints. ([#&#8203;19530](element-hq/synapse#19530))
- Add a few labels to the number groupings in the `Processed request` logs. ([#&#8203;19548](element-hq/synapse#19548))
