When receiving a /send_join request for a room with join rules set to 'restricted',
check if the user is a member of the spaces defined in the 'allow' key of the join rules.
This only applies to an experimental room version, as defined in MSC3083.
Synapse 1.32.2 (2021-04-22)
===========================
This release includes a fix for a regression introduced in 1.32.0.
Bugfixes
--------
- Fix a regression in Synapse 1.32.0 and 1.32.1 which caused `LoggingContext` errors in plugins. ([\#9857](https://github.com/matrix-org/synapse/issues/9857))
1.32.0 also introduced an incompatibility with Synapse modules that make use of `synapse.logging.context.LoggingContext`, such as [synapse-s3-storage-provider](https://github.com/matrix-org/synapse-s3-storage-provider).
This PR adds a note to the 1.32.0 changelog and upgrade notes about it.
Synapse 1.32.1 (2021-04-21)
===========================
This release fixes [a regression](https://github.com/matrix-org/synapse/issues/9853) in Synapse 1.32.0 that caused connected Prometheus instances to become unstable. If you ran Synapse 1.32.0 with Prometheus metrics, first upgrade to Synapse 1.32.1 and follow [these instructions](https://github.com/matrix-org/synapse/pull/9854#issuecomment-823472183) to clean up any excess writeahead logs.
Bugfixes
--------
- Fix a regression in Synapse 1.32.0 which caused Synapse to report large numbers of Prometheus time series, potentially overwhelming Prometheus instances. ([\#9854](https://github.com/matrix-org/synapse/issues/9854))
As far as I can tell our logging contexts are meant to log the request ID, or sometimes the request ID followed by a suffix (this is generally stored in the name field of LoggingContext). There's also code to log the name@memory location, but I'm not sure this is ever used.
This simplifies the code paths to require every logging context to have a name and use that in logging. For sub-contexts (created via nested_logging_contexts, defer_to_threadpool, Measure) we use the current context's str (which becomes their name or the string "sentinel") and then potentially modify that (e.g. add a suffix).
