The expire_access_token didn't do what it sounded like it should do. What it actually did was make Synapse enforce the 'time' caveat on macaroons used as access tokens, but since our access token macaroons never contained such a caveat, it was always a no-op.

(The code to add 'time' caveats was removed back in v0.18.5, in #1656)

This is extra confusing now that we have real code to do access token expiry (#5660)

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))

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

- Make Jaeger fully configurable. ([\#5694](#5694))
- 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))
- Add a prometheus metric for pending cache lookups. ([\#5750](#5750))
- Stop trying to fetch events with event_id=None. ([\#5753](#5753))
- Convert RedactionTestCase to modern test style. ([\#5768](#5768))
- Allow looping calls to be given arguments. ([\#5780](#5780))
- Set the logs emitted when checking typing and presence timeouts to DEBUG level, not INFO. ([\#5785](#5785))
- Remove DelayedCall debugging from the test suite, as it is no longer required in the vast majority of Synapse's tests. ([\#5787](#5787))
- 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))
- Add a lower bound to well-known lookup cache time to avoid repeated lookups. ([\#5836](#5836))
- Whitelist history visbility sytests in worker mode tests. ([\#5843](#5843))
