+Synapse 1.0.0rc2 (2019-06-10)
+=============================
+
+Bugfixes
+--------
+
+- Remove redundant warning about key server response validation. ([\#5392](https://github.com/matrix-org/synapse/issues/5392))
+- Fix bug where old keys stored in the database with a null valid until timestamp caused all verification requests for that key to fail. ([\#5415](https://github.com/matrix-org/synapse/issues/5415))
+- Fix excessive memory using with default `federation_verify_certificates: true` configuration. ([\#5417](https://github.com/matrix-org/synapse/issues/5417))
+
+
+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))
+
+
+Bugfixes
+--------
+
+- Fixes client-server API not sending "m.heroes" to lazy-load /sync requests when a rooms name or its canonical alias are empty. Thanks to @dnaf for this work! ([\#5089](https://github.com/matrix-org/synapse/issues/5089))
+- Prevent federation device list updates breaking when processing multiple updates at once. ([\#5156](https://github.com/matrix-org/synapse/issues/5156))
+- Fix worker registration bug caused by ClientReaderSlavedStore being unable to see get_profileinfo. ([\#5200](https://github.com/matrix-org/synapse/issues/5200))
+- Fix race when backfilling in rooms with worker mode. ([\#5221](https://github.com/matrix-org/synapse/issues/5221))
+- Fix appservice timestamp massaging. ([\#5233](https://github.com/matrix-org/synapse/issues/5233))
+- Ensure that server_keys fetched via a notary server are correctly signed. ([\#5251](https://github.com/matrix-org/synapse/issues/5251))
+- Show the correct error when logging out and access token is missing. ([\#5256](https://github.com/matrix-org/synapse/issues/5256))
+- Fix error code when there is an invalid parameter on /_matrix/client/r0/publicRooms ([\#5257](https://github.com/matrix-org/synapse/issues/5257))
+- Fix error when downloading thumbnail with missing width/height parameter. ([\#5258](https://github.com/matrix-org/synapse/issues/5258))
+- Fix schema update for account validity. ([\#5268](https://github.com/matrix-org/synapse/issues/5268))
+- Fix bug where we leaked extremities when we soft failed events, leading to performance degradation. ([\#5274](https://github.com/matrix-org/synapse/issues/5274), [\#5278](https://github.com/matrix-org/synapse/issues/5278), [\#5291](https://github.com/matrix-org/synapse/issues/5291))
+- Fix "db txn 'update_presence' from sentinel context" log messages. ([\#5275](https://github.com/matrix-org/synapse/issues/5275))
+- Fix dropped logcontexts during high outbound traffic. ([\#5277](https://github.com/matrix-org/synapse/issues/5277))
+- Fix a bug where it is not possible to get events in the federation format with the request `GET /_matrix/client/r0/rooms/{roomId}/messages`. ([\#5293](https://github.com/matrix-org/synapse/issues/5293))
+- Fix performance problems with the rooms stats background update. ([\#5294](https://github.com/matrix-org/synapse/issues/5294))
+- Fix noisy 'no key for server' logs. ([\#5300](https://github.com/matrix-org/synapse/issues/5300))
+- Fix bug where a notary server would sometimes forget old keys. ([\#5307](https://github.com/matrix-org/synapse/issues/5307))
+- Prevent users from setting huge displaynames and avatar URLs. ([\#5309](https://github.com/matrix-org/synapse/issues/5309))
+- Fix handling of failures when processing incoming events where calling `/event_auth` on remote server fails. ([\#5317](https://github.com/matrix-org/synapse/issues/5317))
+- Ensure that we have an up-to-date copy of the signing key when validating incoming federation requests. ([\#5321](https://github.com/matrix-org/synapse/issues/5321))
+- Fix various problems which made the signing-key notary server time out for some requests. ([\#5333](https://github.com/matrix-org/synapse/issues/5333))
+- Fix bug which would make certain operations (such as room joins) block for 20 minutes while attemoting to fetch verification keys. ([\#5334](https://github.com/matrix-org/synapse/issues/5334))
+- Fix a bug where we could rapidly mark a server as unreachable even though it was only down for a few minutes. ([\#5335](https://github.com/matrix-org/synapse/issues/5335), [\#5340](https://github.com/matrix-org/synapse/issues/5340))
+- Fix a bug where account validity renewal emails could only be sent when email notifs were enabled. ([\#5341](https://github.com/matrix-org/synapse/issues/5341))

+Upgrading to v1.0
+=================
+
+Validation of TLS certificates
+------------------------------
+
+Synapse v1.0 is the first release to enforce
+validation of TLS certificates for the federation API. It is therefore
+essential that your certificates are correctly configured. See the `FAQ
+<docs/MSC1711_certificates_FAQ.md>`_ for more information.
+
+Note, v1.0 installations will also no longer be able to federate with servers
+that have not correctly configured their certificates.
+
+In rare cases, it may be desirable to disable certificate checking: for
+example, it might be essential to be able to federate with a given legacy
+server in a closed federation. This can be done in one of two ways:-
+
+* Configure the global switch ``federation_verify_certificates`` to ``false``.
+* Configure a whitelist of server domains to trust via ``federation_certificate_verification_whitelist``.
+
+See the `sample configuration file <docs/sample_config.yaml>`_
+for more details on these settings. 
+
+Email
+-----
+When a user requests a password reset, Synapse will send an email to the 
+user to confirm the request.
+
+Previous versions of Synapse delegated the job of sending this email to an
+identity server. If the identity server was somehow malicious or became
+compromised, it would be theoretically possible to hijack an account through
+this means.
+
+Therefore, by default, Synapse v1.0 will send the confirmation email itself. If
+Synapse is not configured with an SMTP server, password reset via email will be
+disabled.
+
+To configure an SMTP server for Synapse, modify the configuration section
+headed ``email``, and be sure to have at least the ``smtp_host``, ``smtp_port``
+and ``notif_from`` fields filled out. You may also need to set ``smtp_user``,
+``smtp_pass``, and ``require_transport_security``.
+
+If you are absolutely certain that you wish to continue using an identity
+server for password resets, set ``trust_identity_server_for_password_resets`` to ``true``.
+
+See the `sample configuration file <docs/sample_config.yaml>`_
+for more details on these settings.
