-Synapse 1.20.1 (2020-09-24)
-===========================
-
-Bugfixes
---------
-
-- Fix a bug introduced in v1.20.0 which caused the `synapse_port_db` script to fail. ([\#8386](https://github.com/matrix-org/synapse/issues/8386))
-- Fix a bug introduced in v1.20.0 which caused variables to be incorrectly escaped in Jinja2 templates. ([\#8394](https://github.com/matrix-org/synapse/issues/8394))

-Synapse 1.20.0 (2020-09-22)
-===========================
-
-No significant changes since v1.20.0rc5.
+For the next release
+====================
 
 Removal warning
 ---------------
 
-Historically, the [Synapse Admin
-API](https://github.com/matrix-org/synapse/tree/master/docs) has been
-accessible under the `/_matrix/client/api/v1/admin`,
-`/_matrix/client/unstable/admin`, `/_matrix/client/r0/admin` and
-`/_synapse/admin` prefixes. In a future release, we will be dropping support
-for accessing Synapse's Admin API using the `/_matrix/client/*` prefixes. This
-makes it easier for homeserver admins to lock down external access to the Admin
-API endpoints.
-
-Synapse 1.20.0rc5 (2020-09-18)
-==============================
-
-In addition to the below, Synapse 1.20.0rc5 also includes the bug fix that was included in 1.19.3.
-
-Features
---------
-
-- Add flags to the `/versions` endpoint for whether new rooms default to using E2EE. ([\#8343](https://github.com/matrix-org/synapse/issues/8343))
-
-
-Bugfixes
---------
-
-- Fix rate limiting of federation `/send` requests. ([\#8342](https://github.com/matrix-org/synapse/issues/8342))
-- Fix a longstanding bug where back pagination over federation could get stuck if it failed to handle a received event. ([\#8349](https://github.com/matrix-org/synapse/issues/8349))
-
-
-Internal Changes
-----------------
-
-- Blacklist [MSC2753](https://github.com/matrix-org/matrix-doc/pull/2753) SyTests until it is implemented. ([\#8285](https://github.com/matrix-org/synapse/issues/8285))
-
-
-Synapse 1.19.3 (2020-09-18)
-===========================
-
-Bugfixes
---------
-
-- Partially mitigate bug where newly joined servers couldn't get past events in a room when there is a malformed event. ([\#8350](https://github.com/matrix-org/synapse/issues/8350))
-
-
-Synapse 1.20.0rc4 (2020-09-16)
-==============================
-
-Synapse 1.20.0rc4 is identical to 1.20.0rc3, with the addition of the security fix that was included in 1.19.2.
-
-
-Synapse 1.19.2 (2020-09-16)
-===========================
-
-Due to the issue below server admins are encouraged to upgrade as soon as possible.

-
-
-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 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

-- 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))

-- Synapse now correctly enforces the valid characters in the `client_secret` parameter used in various endpoints. ([\#8101](https://github.com/matrix-org/synapse/issues/8101))
-- Fix a bug introduced in v1.7.2 impacting message retention policies that would allow federated homeservers to dictate a retention period that's lower than the configured minimum allowed duration in the configuration file. ([\#8104](https://github.com/matrix-org/synapse/issues/8104))
-- Fix a long-standing bug where invalid JSON would be accepted by Synapse. ([\#8106](https://github.com/matrix-org/synapse/issues/8106))
