Merge tag 'v1.32.0' into babolivier/dinsic_1.41.0

Synapse 1.32.0 (2021-04-20)
===========================

**Note:** This release requires Python 3.6+ and Postgres 9.6+ or SQLite 3.22+.

This release removes the deprecated `GET /_synapse/admin/v1/users/<user_id>` admin API. Please use the [v2 API](https://github.com/matrix-org/synapse/blob/develop/docs/admin_api/user_admin_api.rst#query-user-account) instead, which has improved capabilities.

This release requires Application Services to use type `m.login.application_service` when registering users via the `/_matrix/client/r0/register` endpoint to comply with the spec. Please ensure your Application Services are up to date.

Bugfixes
--------

- Fix the log lines of nested logging contexts. Broke in 1.32.0rc1. ([\#9829](https://github.com/matrix-org/synapse/issues/9829))

Synapse 1.32.0rc1 (2021-04-13)
==============================

Features
--------

- Add a Synapse module for routing presence updates between users. ([\#9491](https://github.com/matrix-org/synapse/issues/9491))
- Add an admin API to manage ratelimit for a specific user. ([\#9648](https://github.com/matrix-org/synapse/issues/9648))
- Include request information in structured logging output. ([\#9654](https://github.com/matrix-org/synapse/issues/9654))
- Add `order_by` to the admin API `GET /_synapse/admin/v2/users`. Contributed by @dklimpel. ([\#9691](https://github.com/matrix-org/synapse/issues/9691))
- Replace the `room_invite_state_types` configuration setting with `room_prejoin_state`. ([\#9700](https://github.com/matrix-org/synapse/issues/9700))
- Add experimental support for [MSC3083](https://github.com/matrix-org/matrix-doc/pull/3083): restricting room access via group membership. ([\#9717](https://github.com/matrix-org/synapse/issues/9717), [\#9735](https://github.com/matrix-org/synapse/issues/9735))
- Update experimental support for Spaces: include `m.room.create` in the room state sent with room-invites. ([\#9710](https://github.com/matrix-org/synapse/issues/9710))
- Synapse now requires Python 3.6 or later. It also requires Postgres 9.6 or later or SQLite 3.22 or later. ([\#9766](https://github.com/matrix-org/synapse/issues/9766))

Bugfixes
--------

- Prevent `synapse_forward_extremities` and `synapse_excess_extremity_events` Prometheus metrics from initially reporting zero-values after startup. ([\#8926](https://github.com/matrix-org/synapse/issues/8926))
- Fix recently added ratelimits to correctly honour the application service `rate_limited` flag. ([\#9711](https://github.com/matrix-org/synapse/issues/9711))
- Fix longstanding bug which caused `duplicate key value violates unique constraint "remote_media_cache_thumbnails_media_origin_media_id_thumbna_key"` errors. ([\#9725](https://github.com/matrix-org/synapse/issues/9725))
- Fix bug where sharded federation senders could get stuck repeatedly querying the DB in a loop, using lots of CPU. ([\#9770](https://github.com/matrix-org/synapse/issues/9770))
- Fix duplicate logging of exceptions thrown during federation transaction processing. ([\#9780](https://github.com/matrix-org/synapse/issues/9780))

Updates to the Docker image
---------------------------

- Move opencontainers labels to the final Docker image such that users can inspect them. ([\#9765](https://github.com/matrix-org/synapse/issues/9765))

Improved Documentation
----------------------

- Make the `allowed_local_3pids` regex example in the sample config stricter. ([\#9719](https://github.com/matrix-org/synapse/issues/9719))

Deprecations and Removals
-------------------------

- Remove old admin API `GET /_synapse/admin/v1/users/<user_id>`. ([\#9401](https://github.com/matrix-org/synapse/issues/9401))
- Make `/_matrix/client/r0/register` expect a type of `m.login.application_service` when an Application Service registers a user, to align with [the relevant spec](https://spec.matrix.org/unstable/application-service-api/#server-admin-style-permissions). ([\#9548](https://github.com/matrix-org/synapse/issues/9548))

Internal Changes
----------------

- Replace deprecated `imp` module with successor `importlib`. Contributed by Cristina Muñoz. ([\#9718](https://github.com/matrix-org/synapse/issues/9718))
- Experiment with GitHub Actions for CI. ([\#9661](https://github.com/matrix-org/synapse/issues/9661))
- Introduce flake8-bugbear to the test suite and fix some of its lint violations. ([\#9682](https://github.com/matrix-org/synapse/issues/9682))
- Update `scripts-dev/complement.sh` to use a local checkout of Complement, allow running a subset of tests and have it use Synapse's Complement test blacklist. ([\#9685](https://github.com/matrix-org/synapse/issues/9685))
- Improve Jaeger tracing for `to_device` messages. ([\#9686](https://github.com/matrix-org/synapse/issues/9686))
- Add release helper script for automating part of the Synapse release process. ([\#9713](https://github.com/matrix-org/synapse/issues/9713))
- Add type hints to expiring cache. ([\#9730](https://github.com/matrix-org/synapse/issues/9730))
- Convert various testcases to `HomeserverTestCase`. ([\#9736](https://github.com/matrix-org/synapse/issues/9736))
- Start linting mypy with `no_implicit_optional`. ([\#9742](https://github.com/matrix-org/synapse/issues/9742))
- Add missing type hints to federation handler and server. ([\#9743](https://github.com/matrix-org/synapse/issues/9743))
- Check that a `ConfigError` is raised, rather than simply `Exception`, when appropriate in homeserver config file generation tests. ([\#9753](https://github.com/matrix-org/synapse/issues/9753))
- Fix incompatibility with `tox` 2.5. ([\#9769](https://github.com/matrix-org/synapse/issues/9769))
- Enable Complement tests for [MSC2946](https://github.com/matrix-org/matrix-doc/pull/2946): Spaces Summary API. ([\#9771](https://github.com/matrix-org/synapse/issues/9771))
- Use mock from the standard library instead of a separate package. ([\#9772](https://github.com/matrix-org/synapse/issues/9772))
