Synapse 1.33.0rc1 (2021-04-28) 

==============================
 
 Features
 --------
 
 - Update experimental support for [MSC3083](https://github.com/matrix-org/matrix-doc/pull/3083): restricting room access via group membership. ([\#9800](https://github.com/matrix-org/synapse/issues/9800), [\#9814](https://github.com/matrix-org/synapse/issues/9814))
 - Add experimental support for handling presence on a worker. ([\#9819](https://github.com/matrix-org/synapse/issues/9819), [\#9820](https://github.com/matrix-org/synapse/issues/9820), [\#9828](https://github.com/matrix-org/synapse/issues/9828), [\#9850](https://github.com/matrix-org/synapse/issues/9850))
 - Return a new template when an user attempts to renew their account multiple times with the same token, stating that their account is set to expire. This replaces the invalid token template that would previously be shown in this case. This change concerns the optional account validity feature. ([\#9832](https://github.com/matrix-org/synapse/issues/9832))
 
 Bugfixes
 --------
 
 - Fixes the OIDC SSO flow when using a `public_baseurl` value including a non-root URL path. ([\#9726](https://github.com/matrix-org/synapse/issues/9726))
 - Fix thumbnail generation for some sites with non-standard content types. Contributed by @rkfg. ([\#9788](https://github.com/matrix-org/synapse/issues/9788))
 - Add some sanity checks to identity server passed to 3PID bind/unbind endpoints. ([\#9802](https://github.com/matrix-org/synapse/issues/9802))
 - Limit the size of HTTP responses read over federation. ([\#9833](https://github.com/matrix-org/synapse/issues/9833))
 - Fix a bug which could cause Synapse to get stuck in a loop of resyncing device lists. ([\#9867](https://github.com/matrix-org/synapse/issues/9867))
 - Fix a long-standing bug where errors from federation did not propagate to the client. ([\#9868](https://github.com/matrix-org/synapse/issues/9868))
 
 Improved Documentation
 ----------------------
 
 - Add a note to the docker docs mentioning that we mirror upstream's supported Docker platforms. ([\#9801](https://github.com/matrix-org/synapse/issues/9801))
 
 Internal Changes
 ----------------
 
 - Add a dockerfile for running Synapse in worker-mode under Complement. ([\#9162](https://github.com/matrix-org/synapse/issues/9162))
 - Apply `pyupgrade` across the codebase. ([\#9786](https://github.com/matrix-org/synapse/issues/9786))
 - Move some replication processing out of `generic_worker`. ([\#9796](https://github.com/matrix-org/synapse/issues/9796))
 - Replace `HomeServer.get_config()` with inline references. ([\#9815](https://github.com/matrix-org/synapse/issues/9815))
 - Rename some handlers and config modules to not duplicate the top-level module. ([\#9816](https://github.com/matrix-org/synapse/issues/9816))
 - Fix a long-standing bug which caused `max_upload_size` to not be correctly enforced. ([\#9817](https://github.com/matrix-org/synapse/issues/9817))
 - Reduce CPU usage of the user directory by reusing existing calculated room membership. ([\#9821](https://github.com/matrix-org/synapse/issues/9821))
 - Small speed up for joining large remote rooms. ([\#9825](https://github.com/matrix-org/synapse/issues/9825))
 - Introduce flake8-bugbear to the test suite and fix some of its lint violations. ([\#9838](https://github.com/matrix-org/synapse/issues/9838))
 - Only store the raw data in the in-memory caches, rather than objects that include references to e.g. the data stores. ([\#9845](https://github.com/matrix-org/synapse/issues/9845))
 - Limit length of accepted email addresses. ([\#9855](https://github.com/matrix-org/synapse/issues/9855))
 - Remove redundant `synapse.types.Collection` type definition. ([\#9856](https://github.com/matrix-org/synapse/issues/9856))
 - Handle recently added rate limits correctly when using `--no-rate-limit` with the demo scripts. ([\#9858](https://github.com/matrix-org/synapse/issues/9858))
 - Disable invite rate-limiting by default when running the unit tests. ([\#9871](https://github.com/matrix-org/synapse/issues/9871))
 - Pass a reactor into `SynapseSite` to make testing easier. ([\#9874](https://github.com/matrix-org/synapse/issues/9874))
 - Make `DomainSpecificString` an `attrs` class. ([\#9875](https://github.com/matrix-org/synapse/issues/9875))
