+- Update to 1.20.0
+  - Removal warning
+    - Some older clients used a disallowed character (:) in the
+      client_secret parameter of various endpoints. The incorrect
+      behaviour was allowed for backwards compatibility, but is now
+      being removed from Synapse as most users have updated their
+      client. Further context can be found at #6766.
+    - Historically, the Synapse Admin API has been accessible under
+      the prefixes:
+      /_matrix/client/api/v1/admin,
+      /_matrix/client/unstable/admin,
+      /_matrix/client/r0/admin
+      /_synapse/admin
+
+      In a future release, we will be dropping support for
+      accessing Synapse's Admin API using the /_matrix/client/*
+      prefixes. This makes it easier for homeserver admins to lock
+      down external access to the Admin API endpoints.
+  - Features
+    - Add flags to the /versions endpoint for whether new rooms
+      default to using E2EE. (#8343)
+    - Add an endpoint to query your shared rooms with another user
+      as an implementation of MSC2666. (#7785)
+    - Iteratively encode JSON to avoid blocking the reactor.
+      (#8013, #8116)
+    - Add support for shadow-banning users (ignoring any message
+      send requests). (#8034, #8092, #8095, #8142, #8152, #8157,
+      #8158, #8176)
+    - Use the default template file when its equivalent is not
+      found in a custom template directory. (#8037, #8107, #8252)
+    - Add unread messages count to sync responses, as specified in
+      MSC2654. (#8059, #8254, #8270, #8274)
+    - Optimise /federation/v1/user/devices/ API by only returning
+      devices with encryption keys. (#8198)
+  - Bugfixes
+    - Fix rate limiting of federation /send requests. (#8342)
+    - Fix a longstanding bug where back pagination over federation
+      could get stuck if it failed to handle a received event.
+      (#8349)
+    - Partially mitigate bug where newly joined servers couldn't
+      get past events in a room when there is a malformed event.
+      (#8350)
+    - Fix joining rooms over federation that include malformed
+      events.  (#8324)
+    - Fix a bug introduced in v1.20.0rc1 where the wrong exception
+      was raised when invalid JSON data is encountered.  (#8291)
+    - Fix a bug introduced in v1.20.0rc1 causing some features
+      related to notifications to misbehave following the
+      implementation of unread counts. (#8280)
+    - Fix a memory leak by limiting the length of time that
+      messages will be queued for a remote server that has been
+      unreachable. (#7864)
+    - Fix Re-starting finished log context PUT-nnnn warning when
+      event persistence failed. (#8081)
+    - Synapse now correctly enforces the valid characters in the
+      client_secret parameter used in various endpoints. (#8101)
+    - Fix a bug introduced in v1.7.2 impacting message retention
+      policies that would allow federated homeservers to dictate a
+      retention period that's lower than the configured minimum
+      allowed duration in the configuration file. (#8104)
+    - Fix a long-standing bug where invalid JSON would be accepted
+      by Synapse. (#8106)
+    - Fix a bug introduced in Synapse v1.12.0 which could cause
+      /sync requests to fail with a 404 if you had a very old
+      outstanding room invite. (#8110)
+    - Return a proper error code when the rooms of an invalid group
+      are requested. (#8129)
+    - Fix a bug which could cause a leaked postgres connection if
+      synapse was set to daemonize. (#8131)
+    - Clarify the error code if a user tries to register with a
+      numeric ID. This bug was introduced in v1.15.0. (#8135)
+    - Fix a bug where appservices with ratelimiting disabled would
+      still be ratelimited when joining rooms. This bug was
+      introduced in v1.19.0. (#8139)
+    - Fix logging in via OpenID Connect with a provider that uses
+      integer user IDs. (#8190)
+    - Fix a longstanding bug where user directory updates could
+      break when unexpected profile data was included in events.
+      (#8223)
+    - Fix a longstanding bug where stats updates could break when
+      unexpected profile data was included in events. (#8226)
+    - Fix slow start times for large servers by removing a table
+      scan of the users table from startup code. (#8271)
+  - Improved Documentation
+    - Link to matrix-synapse-rest-password-provider in the password
+      provider documentation. (#8111)
+    - Updated documentation to note that Synapse does not follow
+      HTTP 308 redirects due to an upstream library not supporting
+      them. Contributed by Ryan Cole. (#8120)
+    - Explain better what GDPR-erased means when deactivating a
+      user. (#8189)
+  - Internal Changes
+    - Blacklist MSC2753 SyTests until it is implemented. (#8285)
+    - Add filter name to the /users admin API, which filters by
+      user ID or displayname. Contributed by Awesome Technologies
+      Innovationslabor GmbH. (#7377, #8163)
+    - Reduce run times of some unit tests by advancing the reactor
+      a fewer number of times. (#7757)
+    - Don't fail /submit_token requests on incorrect session ID if
+      request_token_inhibit_3pid_errors is turned on. (#7991)
+    - Convert various parts of the codebase to async/await. (#8071,
+      #8072, #8074, #8075, #8076, #8087, #8100, #8119, #8121,
+      #8133, #8156, #8162, #8166, #8168, #8173, #8191, #8192,

+      #8207, #8213, #8214)
+    - Remove some unused database functions. (#8085)
+    - Add type hints to various parts of the codebase. (#8090,
+      #8127, #8187, #8241, #8140, #8183, #8232, #8235, #8237,
+      #8244)
+    - Return the previous stream token if a non-member event is a
+      duplicate. (#8093, #8112)
+    - Separate get_current_token into two since there are two
+      different use cases for it. (#8113)
+    - Remove ChainedIdGenerator. (#8123)
+    - Reduce the amount of whitespace in JSON stored and sent in
+      responses. (#8124)
+    - Update the test federation client to handle streaming
+      responses. (#8130)
+    - Micro-optimisations to get_auth_chain_ids. (#8132)
+    - Refactor StreamIdGenerator and MultiWriterIdGenerator to have
+      the same interface. (#8161)
+    - Add functions to MultiWriterIdGen used by events stream.
+      (#8164, #8179)
+    - Fix tests that were broken due to the merge of 1.19.1.
+      (#8167)
+    - Make SlavedIdTracker.advance have the same interface as
+      MultiWriterIDGenerator. (#8171)
+    - Remove unused is_guest parameter from, and add safeguard to,
+      MessageHandler.get_room_data. (#8174, #8181)
+    - Standardize the mypy configuration. (#8175)
+    - Refactor some of LoginRestServlet's helper methods, and move
+      them to AuthHandler for easier reuse. (#8182)
+    - Fix wait_for_stream_position to allow multiple waiters on
+      same stream ID. (#8196)
+    - Make MultiWriterIDGenerator work for streams that use
+      negative values. (#8203)
+    - Refactor queries for device keys and cross-signatures.
+      (#8204, #8205, #8222, #8224, #8225, #8231, #8233, #8234)
