Background: we have a matrixdotorg/synapse-workers docker image, which is intended for running multiple workers within the same container. That image includes a prefix-log script which, for each line printed to stdout or stderr by one of the processes, prepends the name of the process.

This commit disables buffering in that script, so that lines are logged quickly after they are printed. This makes it much easier to understand the output, since they then come out in a natural order.

# Synapse 1.104.0 (2024-04-02)

### Bugfixes

- Fix regression when using OIDC provider. Introduced in v1.104.0rc1. ([\#17031](element-hq/synapse#17031))


# Synapse 1.104.0rc1 (2024-03-26)

### Features

- Add an OIDC config to specify extra parameters for the authorization grant URL. IT can be useful to pass an ACR value for example. ([\#16971](element-hq/synapse#16971))
- Add support for OIDC provider returning JWT. ([\#16972](element-hq/synapse#16972), [\#17031](element-hq/synapse#17031))

### Bugfixes

- Fix a bug which meant that, under certain circumstances, we might never retry sending events or to-device messages over federation after a failure. ([\#16925](element-hq/synapse#16925))
- Fix various long-standing bugs which could cause incorrect state to be returned from `/sync` in certain situations. ([\#16949](element-hq/synapse#16949))
- Fix case in which `m.fully_read` marker would not get updated. Contributed by @SpiritCroc. ([\#16990](element-hq/synapse#16990))
- Fix bug which did not retract a user's pending knocks at rooms when their account was deactivated. Contributed by @hanadi92. ([\#17010](element-hq/synapse#17010))

### Updates to the Docker image

- Updated `start.py` to generate config using the correct user ID when running as root (fixes [\#16824](element-hq/synapse#16824), [\#15202](element-hq/synapse#15202)). ([\#16978](element-hq/synapse#16978))

### Improved Documentation

- Add a query to force a refresh of a remote user's device list to the "Useful SQL for Admins" documentation page. ([\#16892](element-hq/synapse#16892))
- Minor grammatical corrections to the upgrade documentation. ([\#16965](element-hq/synapse#16965))
- Fix the sort order for the documentation version picker, so that newer releases appear above older ones. ([\#16966](element-hq/synapse#16966))
- Remove recommendation for a specific poetry version from contributing guide. ([\#17002](element-hq/synapse#17002))

### Internal Changes

- Improve lock performance when a lot of locks are all waiting for a single lock to be released. ([\#16840](element-hq/synapse#16840))
- Update power level default for public rooms. ([\#16907](element-hq/synapse#16907))
- Improve event validation. ([\#16908](element-hq/synapse#16908))
- Multi-worker-docker-container: disable log buffering. ([\#16919](element-hq/synapse#16919))
- Refactor state delta calculation in `/sync` handler. ([\#16929](element-hq/synapse#16929))
- Clarify docs for some room state functions. ([\#16950](element-hq/synapse#16950))
- Specify IP subnets in canonical form. ([\#16953](element-hq/synapse#16953))
- As done for SAML mapping provider, let's pass the module API to the OIDC one so the mapper can do more logic in its code. ([\#16974](element-hq/synapse#16974))
- Allow containers building on top of Synapse's Complement container is use the included PostgreSQL cluster. ([\#16985](element-hq/synapse#16985))
- Raise poetry-core version cap to 1.9.0. ([\#16986](element-hq/synapse#16986))
- Patch the db conn pool sooner in tests. ([\#17017](element-hq/synapse#17017))

### Features
