Synapse 1.29.0rc1 (2021-03-04)

==============================

Note that synapse now expects an `X-Forwarded-Proto` header when used with a reverse proxy. Please see [UPGRADE.rst](UPGRADE.rst#upgrading-to-v1290) for more details on this change.

Features
--------

- Add rate limiters to cross-user key sharing requests. ([\#8957](https://github.com/matrix-org/synapse/issues/8957))
- Add `order_by` to the admin API `GET /_synapse/admin/v1/users/<user_id>/media`. Contributed by @dklimpel. ([\#8978](https://github.com/matrix-org/synapse/issues/8978))
- Add some configuration settings to make users' profile data more private. ([\#9203](https://github.com/matrix-org/synapse/issues/9203))
- The `no_proxy` and `NO_PROXY` environment variables are now respected in proxied HTTP clients with the lowercase form taking precedence if both are present. Additionally, the lowercase `https_proxy` environment variable is now respected in proxied HTTP clients on top of existing support for the uppercase `HTTPS_PROXY` form and takes precedence if both are present. Contributed by Timothy Leung. ([\#9372](https://github.com/matrix-org/synapse/issues/9372))
- Add a configuration option, `user_directory.prefer_local_users`, which when enabled will make it more likely for users on the same server as you to appear above other users. ([\#9383](https://github.com/matrix-org/synapse/issues/9383), [\#9385](https://github.com/matrix-org/synapse/issues/9385))
- Add support for regenerating thumbnails if they have been deleted but the original image is still stored. ([\#9438](https://github.com/matrix-org/synapse/issues/9438))
- Add support for `X-Forwarded-Proto` header when using a reverse proxy. ([\#9472](https://github.com/matrix-org/synapse/issues/9472), [\#9501](https://github.com/matrix-org/synapse/issues/9501), [\#9512](https://github.com/matrix-org/synapse/issues/9512), [\#9539](https://github.com/matrix-org/synapse/issues/9539))
