Synapse 1.3.0 (2019-08-15)
==========================

Bugfixes
--------

- Fix 500 Internal Server Error on `publicRooms` when the public room list was
  cached. ([\#5851](#5851))

Synapse 1.3.0rc1 (2019-08-13)
==========================

Features
--------

- Use `M_USER_DEACTIVATED` instead of `M_UNKNOWN` for errcode when a deactivated user attempts to login. ([\#5686](#5686))
- Add sd_notify hooks to ease systemd integration and allows usage of Type=Notify. ([\#5732](#5732))
- Synapse will no longer serve any media repo admin endpoints when `enable_media_repo` is set to False in the configuration. If a media repo worker is used, the admin APIs relating to the media repo will be served from it instead. ([\#5754](#5754), [\#5848](#5848))
- Synapse can now be configured to not join remote rooms of a given "complexity" (currently, state events) over federation. This option can be used to prevent adverse performance on resource-constrained homeservers. ([\#5783](#5783))
- Allow defining HTML templates to serve the user on account renewal attempt when using the account validity feature. ([\#5807](#5807))

Bugfixes
--------

- Fix UISIs during homeserver outage. ([\#5693](#5693), [\#5789](#5789))
- Fix stack overflow in server key lookup code. ([\#5724](#5724))
- start.sh no longer uses deprecated cli option. ([\#5725](#5725))
- Log when we receive an event receipt from an unexpected origin. ([\#5743](#5743))
- Fix debian packaging scripts to correctly build sid packages. ([\#5775](#5775))
- Correctly handle redactions of redactions. ([\#5788](#5788))
- Return 404 instead of 403 when accessing /rooms/{roomId}/event/{eventId} for an event without the appropriate permissions. ([\#5798](#5798))
- Fix check that tombstone is a state event in push rules. ([\#5804](#5804))
- Fix error when trying to login as a deactivated user when using a worker to handle login. ([\#5806](#5806))
- Fix bug where user `/sync` stream could get wedged in rare circumstances. ([\#5825](#5825))
- The purge_remote_media.sh script was fixed. ([\#5839](#5839))

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

- Synapse now no longer accepts the `-v`/`--verbose`, `-f`/`--log-file`, or `--log-config` command line flags, and removes the deprecated `verbose` and `log_file` configuration file options. Users of these options should migrate their options into the dedicated log configuration. ([\#5678](#5678), [\#5729](#5729))
- Remove non-functional 'expire_access_token' setting. ([\#5782](#5782))

- Add precautionary measures to prevent future abuse of `window.opener` in default welcome page. ([\#5695](#5695))
- Reduce database IO usage by optimising queries for current membership. ([\#5706](#5706), [\#5738](#5738), [\#5746](#5746), [\#5752](#5752), [\#5770](#5770), [\#5774](#5774), [\#5792](#5792), [\#5793](#5793))
- Improve caching when fetching `get_filtered_current_state_ids`. ([\#5713](#5713))
- Don't accept opentracing data from clients. ([\#5715](#5715))
- Speed up PostgreSQL unit tests in CI. ([\#5717](#5717))
- Update the coding style document. ([\#5719](#5719))
- Improve database query performance when recording retry intervals for remote hosts. ([\#5720](#5720))
- Add a set of opentracing utils. ([\#5722](#5722))
- Cache result of get_version_string to reduce overhead of `/version` federation requests. ([\#5730](#5730))
- Return 'user_type' in admin API user endpoints results. ([\#5731](#5731))
- Don't package the sytest test blacklist file. ([\#5733](#5733))
- Replace uses of returnValue with plain return, as returnValue is not needed on Python 3. ([\#5736](#5736))
- Blacklist some flakey tests in worker mode. ([\#5740](#5740))
- Fix some error cases in the caching layer. ([\#5749](#5749))

- Remove some spurious exceptions from the logs where we failed to talk to a remote server. ([\#5790](#5790))
- Improve performance when making `.well-known` requests by sharing the SSL options between requests. ([\#5794](#5794))
- Disable codecov GitHub comments on PRs. ([\#5796](#5796))
- Don't allow clients to send tombstone events that reference the room it's sent in. ([\#5801](#5801))
- Deny redactions of events sent in a different room. ([\#5802](#5802))
- Deny sending well known state types as non-state events. ([\#5805](#5805))
- Handle incorrectly encoded query params correctly by returning a 400. ([\#5808](#5808))
- Handle pusher being deleted during processing rather than logging an exception. ([\#5809](#5809))
- Return 502 not 500 when failing to reach any remote server. ([\#5810](#5810))
- Reduce global pauses in the events stream caused by expensive state resolution during persistence. ([\#5826](#5826))

…s_rooms (matrix-org#7387)

populate_stats_process_rooms was added in matrix-org#5971 / v1.4.0; current_state_events_membership was added in matrix-org#5706 / v1.3.0.

Fixes matrix-org#7380.

…tate_events`

`current_state_events` was added in #5706
and #13745

…_state_events` (#15731)

This helps with the upstream `is_host_joined()` and `is_host_invited()` functions.

`membership` was added to `current_state_events` in #5706 and forced in #13745
