Synapse 1.0.0rc1 (2019-06-07)
=============================

Features
--------

- Synapse now more efficiently collates room statistics. ([\#4338](https://github.com/matrix-org/synapse/issues/4338), [\#5260](https://github.com/matrix-org/synapse/issues/5260), [\#5324](https://github.com/matrix-org/synapse/issues/5324))
- Add experimental support for relations (aka reactions and edits). ([\#5220](https://github.com/matrix-org/synapse/issues/5220))
- Ability to configure default room version. ([\#5223](https://github.com/matrix-org/synapse/issues/5223), [\#5249](https://github.com/matrix-org/synapse/issues/5249))
- Allow configuring a range for the account validity startup job. ([\#5276](https://github.com/matrix-org/synapse/issues/5276))
- CAS login will now hit the r0 API, not the deprecated v1 one. ([\#5286](https://github.com/matrix-org/synapse/issues/5286))
- Validate federation server TLS certificates by default (implements [MSC1711](https://github.com/matrix-org/matrix-doc/blob/master/proposals/1711-x509-for-federation.md)). ([\#5359](https://github.com/matrix-org/synapse/issues/5359))
- Update /_matrix/client/versions to reference support for r0.5.0. ([\#5360](https://github.com/matrix-org/synapse/issues/5360))
- Add a script to generate new signing-key files. ([\#5361](https://github.com/matrix-org/synapse/issues/5361))
- Update upgrade and installation guides ahead of 1.0. ([\#5371](https://github.com/matrix-org/synapse/issues/5371))
- Replace the `perspectives` configuration section with `trusted_key_servers`, and make validating the signatures on responses optional (since TLS will do this job for us). ([\#5374](https://github.com/matrix-org/synapse/issues/5374))
- Add ability to perform password reset via email without trusting the identity server. ([\#5377](https://github.com/matrix-org/synapse/issues/5377))
- Set default room version to v4. ([\#5379](https://github.com/matrix-org/synapse/issues/5379))
