Update chat/matrix-synapse to 1.23.0

Synapse 1.23.0 (2020-11-18)
===========================

This release changes the way structured logging is configured. See the [upgrade \ 
notes](UPGRADE.rst#upgrading-to-v1230) for details.

**Note**: We are aware of a trivially exploitable denial of service \ 
vulnerability in versions of Synapse prior to 1.20.0. Complete details will be \ 
disclosed on Monday, November 23rd. If you have not upgraded recently, please do \ 
so.

Bugfixes
--------

- Fix a dependency versioning bug in the Dockerfile that prevented Synapse from \ 
starting. ([\#8767](https://github.com/matrix-org/synapse/issues/8767))

Synapse 1.23.0rc1 (2020-11-13)
==============================

Features
--------

- Add a push rule that highlights when a jitsi conference is created in a room. \ 
([\#8286](https://github.com/matrix-org/synapse/issues/8286))
- Add an admin api to delete a single file or files that were not used for a \ 
defined time from server. Contributed by @dklimpel. \ 
([\#8519](https://github.com/matrix-org/synapse/issues/8519))
- Split admin API for reported events (`GET /_synapse/admin/v1/event_reports`) \ 
into detail and list endpoints. This is a breaking change to #8217 which was \ 
introduced in Synapse v1.21.0. Those who already use this API should check their \ 
scripts. Contributed by @dklimpel. \ 
([\#8539](https://github.com/matrix-org/synapse/issues/8539))
- Support generating structured logs via the standard logging configuration. \ 
([\#8607](https://github.com/matrix-org/synapse/issues/8607), \ 
[\#8685](https://github.com/matrix-org/synapse/issues/8685))
- Add an admin API to allow server admins to list users' pushers. Contributed by \ 
@dklimpel. ([\#8610](https://github.com/matrix-org/synapse/issues/8610), \ 
[\#8689](https://github.com/matrix-org/synapse/issues/8689))
- Add an admin API `GET /_synapse/admin/v1/users/<user_id>/media` to get \ 
information about uploaded media. Contributed by @dklimpel. \ 
([\#8647](https://github.com/matrix-org/synapse/issues/8647))
- Add an admin API for local user media statistics. Contributed by @dklimpel. \ 
([\#8700](https://github.com/matrix-org/synapse/issues/8700))

([\#8722](https://github.com/matrix-org/synapse/issues/8722))

Bugfixes
--------

master key and device signing key is cached already. \ 
([\#8455](https://github.com/matrix-org/synapse/issues/8455))

clients when retrieving profile information. \ 
([\#8580](https://github.com/matrix-org/synapse/issues/8580))
- Fix a bug where the account validity endpoint would silently fail if the user \ 
ID did not have an expiration time. It now returns a 400 error. \ 
([\#8620](https://github.com/matrix-org/synapse/issues/8620))
- Fix email notifications for invites without local state. \ 
([\#8627](https://github.com/matrix-org/synapse/issues/8627))

and return a 500. ([\#8628](https://github.com/matrix-org/synapse/issues/8628))
- Fix handling of User-Agent headers that are invalid UTF-8, which caused user \ 
agents of users to not get correctly recorded. \ 
([\#8632](https://github.com/matrix-org/synapse/issues/8632))
- Fix a bug in the `joined_rooms` admin API if the user has never joined any \ 
rooms. The bug was introduced, along with the API, in v1.21.0. \ 
([\#8643](https://github.com/matrix-org/synapse/issues/8643))
- Fix exception during handling multiple concurrent requests for remote media \ 
when using multiple media repositories. \ 
([\#8682](https://github.com/matrix-org/synapse/issues/8682))
- Fix bug that prevented Synapse from recovering after losing connection to the \ 
database. ([\#8726](https://github.com/matrix-org/synapse/issues/8726))
- Fix bug where the `/_synapse/admin/v1/send_server_notice` API could send \ 
notices to non-notice rooms. \ 
([\#8728](https://github.com/matrix-org/synapse/issues/8728))

v1.21.0. ([\#8729](https://github.com/matrix-org/synapse/issues/8729))
- Fix PostgreSQL port script to correctly handle foreign key constraints. Broke \ 
in v1.21.0. ([\#8730](https://github.com/matrix-org/synapse/issues/8730))

in v1.21.0. ([\#8755](https://github.com/matrix-org/synapse/issues/8755))
