It landed in schema version 58 after 59 had been created, causing some
servers to not run it. The main effect of was that not all rooms had
their chain cover calculated correctly. After the BG updates complete
the chain covers will get fixed when a new state event in the affected
rooms is received.

Also I can't really tell from the github UI -- is this a copy or a move of that file? 😕

It's a move, so that new servers don't run both delta files.

I'm pretty sure this should be fine. Will this cause any issues for servers which have run the background update (will the insert fail in the delta if it already exists? What if a server is still chunking through this background update, will it blow away progress?)

The background update should do the right thing if re-run (as it needs to handle the case where new rejected events are inserted correctly into the metadata tables).

This will break if the previous background update is still in progress, as there's a unique index on background_updates, will fix.

Synapse 1.29.0 (2021-03-08)
===========================

Note that synapse now expects an `X-Forwarded-Proto` header when used with a reverse proxy. Please see [UPGRADE.rst](UPGRADE.rst#upgrading-to-v1290) for more details on this change.


No significant changes.


Synapse 1.29.0rc1 (2021-03-04)
==============================

Features
--------

- Add rate limiters to cross-user key sharing requests. ([\#8957](matrix-org/synapse#8957))
- Add `order_by` to the admin API `GET /_synapse/admin/v1/users/<user_id>/media`. Contributed by @dklimpel. ([\#8978](matrix-org/synapse#8978))
- Add some configuration settings to make users' profile data more private. ([\#9203](matrix-org/synapse#9203))
- The `no_proxy` and `NO_PROXY` environment variables are now respected in proxied HTTP clients with the lowercase form taking precedence if both are present. Additionally, the lowercase `https_proxy` environment variable is now respected in proxied HTTP clients on top of existing support for the uppercase `HTTPS_PROXY` form and takes precedence if both are present. Contributed by Timothy Leung. ([\#9372](matrix-org/synapse#9372))
- Add a configuration option, `user_directory.prefer_local_users`, which when enabled will make it more likely for users on the same server as you to appear above other users. ([\#9383](matrix-org/synapse#9383), [\#9385](matrix-org/synapse#9385))
- Add support for regenerating thumbnails if they have been deleted but the original image is still stored. ([\#9438](matrix-org/synapse#9438))
- Add support for `X-Forwarded-Proto` header when using a reverse proxy. ([\#9472](matrix-org/synapse#9472), [\#9501](matrix-org/synapse#9501), [\#9512](matrix-org/synapse#9512), [\#9539](matrix-org/synapse#9539))


Bugfixes
--------

- Fix a bug where users' pushers were not all deleted when they deactivated their account. ([\#9285](matrix-org/synapse#9285), [\#9516](matrix-org/synapse#9516))
- Fix a bug where a lot of unnecessary presence updates were sent when joining a room. ([\#9402](matrix-org/synapse#9402))
- Fix a bug that caused multiple calls to the experimental `shared_rooms` endpoint to return stale results. ([\#9416](matrix-org/synapse#9416))
- Fix a bug in single sign-on which could cause a "No session cookie found" error. ([\#9436](matrix-org/synapse#9436))
- Fix bug introduced in v1.27.0 where allowing a user to choose their own username when logging in via single sign-on did not work unless an `idp_icon` was defined. ([\#9440](matrix-org/synapse#9440))
- Fix a bug introduced in v1.26.0 where some sequences were not properly configured when running `synapse_port_db`. ([\#9449](matrix-org/synapse#9449))
- Fix deleting pushers when using sharded pushers. ([\#9465](matrix-org/synapse#9465), [\#9466](matrix-org/synapse#9466), [\#9479](matrix-org/synapse#9479), [\#9536](matrix-org/synapse#9536))
- Fix missing startup checks for the consistency of certain PostgreSQL sequences. ([\#9470](matrix-org/synapse#9470))
- Fix a long-standing bug where the media repository could leak file descriptors while previewing media. ([\#9497](matrix-org/synapse#9497))
- Properly purge the event chain cover index when purging history. ([\#9498](matrix-org/synapse#9498))
- Fix missing chain cover index due to a schema delta not being applied correctly. Only affected servers that ran development versions. ([\#9503](matrix-org/synapse#9503))
- Fix a bug introduced in v1.25.0 where `/_synapse/admin/join/` would fail when given a room alias. ([\#9506](matrix-org/synapse#9506))
- Prevent presence background jobs from running when presence is disabled. ([\#9530](matrix-org/synapse#9530))
- Fix rare edge case that caused a background update to fail if the server had rejected an event that had duplicate auth events. ([\#9537](matrix-org/synapse#9537))


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

- Update the example systemd config to propagate reloads to individual units. ([\#9463](matrix-org/synapse#9463))


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

- Add documentation and type hints to `parse_duration`. ([\#9432](matrix-org/synapse#9432))
- Remove vestiges of `uploads_path` configuration setting. ([\#9462](matrix-org/synapse#9462))
- Add a comment about systemd-python. ([\#9464](matrix-org/synapse#9464))
- Test that we require validated email for email pushers. ([\#9496](matrix-org/synapse#9496))
- Allow python to generate bytecode for synapse. ([\#9502](matrix-org/synapse#9502))
- Fix incorrect type hints. ([\#9515](matrix-org/synapse#9515), [\#9518](matrix-org/synapse#9518))
- Add type hints to device and event report admin API. ([\#9519](matrix-org/synapse#9519))
- Add type hints to user admin API. ([\#9521](matrix-org/synapse#9521))
- Bump the versions of mypy and mypy-zope used for static type checking. ([\#9529](matrix-org/synapse#9529))
