+# Synapse 1.125.0rc1 (2025-02-18)
+
+### Features
+
+- Add functionality to be able to use multiple values in SSO feature `attribute_requirements`. ([\#17949](https://github.com/element-hq/synapse/issues/17949))
+- Add experimental config options `admin_token_path` and `client_secret_path` for MSC 3861. ([\#18004](https://github.com/element-hq/synapse/issues/18004))
+- Add `get_current_time_msec()` method to the [module API](https://matrix-org.github.io/synapse/latest/modules/writing_a_module.html) for sound time comparisons with Synapse. ([\#18144](https://github.com/element-hq/synapse/issues/18144))
+
+### Bugfixes
+
+- Fix a bug when updating a user 3pid with invalid returns 500 server error change to 400 with a message. ([\#18125](https://github.com/element-hq/synapse/issues/18125))
+- Fix user directory search when using a legacy module with a `check_username_for_spam` callback. Broke in v1.122.0. ([\#18135](https://github.com/element-hq/synapse/issues/18135))
+- Add rate limit `rc_presence.per_user`. This prevents load from excessive presence updates sent by clients via sync api. Also rate limit `/_matrix/client/v3/presence` as per the spec. Contributed by @rda0. ([\#18145](https://github.com/element-hq/synapse/issues/18145))
+
+### Updates to the Docker image
+
+- Add `SYNAPSE_HTTP_PROXY`/`SYNAPSE_HTTPS_PROXY`/`SYNAPSE_NO_PROXY` environment variables to pass through specifically to the Synapse process (instead of needing to apply [`http_proxy`/`https_proxy`/`no_proxy`](https://element-hq.github.io/synapse/latest/setup/forward_proxy.html) globally). ([\#18158](https://github.com/element-hq/synapse/issues/18158))
+
+### Improved Documentation
+
+- Add Oracle Linux 8 and 9 installation instructions. ([\#17436](https://github.com/element-hq/synapse/issues/17436))
+- Document missing server config options (`daemonize`, `print_pidfile`, `user_agent_suffix`, `use_frozen_dicts`, `manhole`). ([\#18122](https://github.com/element-hq/synapse/issues/18122))
+- Document consequences of replacing secrets. ([\#18138](https://github.com/element-hq/synapse/issues/18138))
+- Make `burst_count` field an integer in `rc_presence` config documentation example. ([\#18159](https://github.com/element-hq/synapse/issues/18159))
+
+### Internal Changes
+
+- Overload DatabasePool.simple_select_one_txn to return non-None when the allow_none parameter is False. ([\#17616](https://github.com/element-hq/synapse/issues/17616))
+- Python 3.8 EOL: compile native extensions with the 3.9 ABI and use typing hints from the standard library. ([\#17967](https://github.com/element-hq/synapse/issues/17967))
+- Add log message when worker lock timeouts get large. ([\#18124](https://github.com/element-hq/synapse/issues/18124))
+- Make it explicit that you can buy an AGPL-alternative commercial license from Element. ([\#18134](https://github.com/element-hq/synapse/issues/18134))
+- Fix the 'Fix linting' GitHub Actions workflow. ([\#18136](https://github.com/element-hq/synapse/issues/18136))
+- Do not log at the exception-level when clients provide empty `since` token to `/sync` API. ([\#18139](https://github.com/element-hq/synapse/issues/18139))
+- Reduce database load of user search when using large search terms. ([\#18172](https://github.com/element-hq/synapse/issues/18172))
+
+
+
