+Synapse 1.20.0rc1 (2020-09-08)
+==============================
 
 Removal warning
 ---------------
 
-Some older clients used a
-[disallowed character](https://matrix.org/docs/spec/client_server/r0.6.1#post-matrix-client-r0-register-email-requesttoken)
-(`:`) in the `client_secret` parameter of various endpoints. The incorrect

-from Synapse as most users have updated their client. Further context can be

+Some older clients used a [disallowed character](https://matrix.org/docs/spec/client_server/r0.6.1#post-matrix-client-r0-register-email-requesttoken) (`:`) in the `client_secret` parameter of various endpoints. The incorrect behaviour was allowed for backwards compatibility, but is now being removed from Synapse as most users have updated their client. Further context can be found at [\#6766](https://github.com/matrix-org/synapse/issues/6766).
+
+Features
+--------
+
+- Add an endpoint to query your shared rooms with another user as an implementation of [MSC2666](https://github.com/matrix-org/matrix-doc/pull/2666). ([\#7785](https://github.com/matrix-org/synapse/issues/7785))
+- Iteratively encode JSON to avoid blocking the reactor. ([\#8013](https://github.com/matrix-org/synapse/issues/8013), [\#8116](https://github.com/matrix-org/synapse/issues/8116))
