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))
