No significant changes.

Synapse 0.99.5rc1 (2019-05-21)
==============================

Features
--------

- Add ability to blacklist IP ranges for the federation client. ([\#5043](https://github.com/matrix-org/synapse/issues/5043))
- Ratelimiting configuration for clients sending messages and the federation server has been altered to match login ratelimiting. The old configuration names will continue working. Check the sample config for details of the new names. ([\#5181](https://github.com/matrix-org/synapse/issues/5181))
- Drop support for the undocumented /_matrix/client/v2_alpha API prefix. ([\#5190](https://github.com/matrix-org/synapse/issues/5190))
- Add an option to disable per-room profiles. ([\#5196](https://github.com/matrix-org/synapse/issues/5196))
- Stick an expiration date to any registered user missing one at startup if account validity is enabled. ([\#5204](https://github.com/matrix-org/synapse/issues/5204))
- Add experimental support for relations (aka reactions and edits). ([\#5209](https://github.com/matrix-org/synapse/issues/5209), [\#5211](https://github.com/matrix-org/synapse/issues/5211), [\#5203](https://github.com/matrix-org/synapse/issues/5203), [\#5212](https://github.com/matrix-org/synapse/issues/5212))

Bugfixes
--------

Synapse 0.99.3rc1 (2019-03-27)
-----------------------------

Features
--------

- The user directory has been rewritten to make it faster, with less chance of falling behind on a large server. ([\#4537](https://github.com/matrix-org/synapse/issues/4537), [\#4846](https://github.com/matrix-org/synapse/issues/4846), [\#4864](https://github.com/matrix-org/synapse/issues/4864), [\#4887](https://github.com/matrix-org/synapse/issues/4887), [\#4900](https://github.com/matrix-org/synapse/issues/4900), [\#4944](https://github.com/matrix-org/synapse/issues/4944))

- Move server key queries to federation reader. ([\#4757](https://github.com/matrix-org/synapse/issues/4757))
- Add support for /account/3pid REST endpoint to client_reader worker. ([\#4759](https://github.com/matrix-org/synapse/issues/4759))
- Add an endpoint to the admin API for querying the server version. Contributed by Joseph Weston. ([\#4772](https://github.com/matrix-org/synapse/issues/4772))
- Include a default configuration file in the 'docs' directory. ([\#4791](https://github.com/matrix-org/synapse/issues/4791), [\#4801](https://github.com/matrix-org/synapse/issues/4801))
- Synapse is now permissive about trailing slashes on some of its federation endpoints, allowing zero or more to be present. ([\#4793](https://github.com/matrix-org/synapse/issues/4793))
- Add support for /keys/query and /keys/changes REST endpoints to client_reader worker. ([\#4796](https://github.com/matrix-org/synapse/issues/4796))

- Allow passing --daemonize flags to workers in the same way as with master. ([\#4853](https://github.com/matrix-org/synapse/issues/4853))
- Batch up outgoing read-receipts to reduce federation traffic. ([\#4890](https://github.com/matrix-org/synapse/issues/4890), [\#4927](https://github.com/matrix-org/synapse/issues/4927))
- Add option to disable searching the user directory. ([\#4895](https://github.com/matrix-org/synapse/issues/4895))
- Add option to disable searching of local and remote public room lists. ([\#4896](https://github.com/matrix-org/synapse/issues/4896))
