+## Dynamic DNS support
+
+Thanks to [Scott Crossen](https://github.com/scottcrossen), the playbook can now manage Dynamic DNS for you using [ddclient](https://ddclient.net/).
+
+To learn more, follow our [Dynamic DNS docs page](docs/configuring-playbook-dynamic-dns.md).
+
+
+# 2020-10-28
+
+## (Compatibility Break) https://matrix.DOMAIN/ now redirects to https://element.DOMAIN/
+
+Until now, we used to serve a static page coming from Synapse at `https://matrix.DOMAIN/`. This page was not very useful to anyone.
+
+Since `matrix.DOMAIN` may be accessed by regular users in certain conditions, it's probably better to redirect them to a better place (e.g. to the [Element](docs/configuring-playbook-client-element.md) client).
+
+If Element is installed (`matrix_client_element_enabled: true`, which it is by default), we now redirect people to it, instead of showing them a Synapse static page.
+
+If you'd like to control where the redirect goes, use the `matrix_nginx_proxy_proxy_matrix_client_redirect_root_uri_to_domain` variable.
+To restore the old behavior of not redirecting anywhere and serving the Synapse static page, set it to an empty value (`matrix_nginx_proxy_proxy_matrix_client_redirect_root_uri_to_domain: ""`).
+
+
+# 2020-10-26
+
+## (Compatibility Break) /_synapse/admin is no longer publicly exposed by default
+
+We used to expose the Synapse Admin APIs publicly (at `https://matrix.DOMAIN/_synapse/admin`).
+These APIs require authentication with a valid access token, so it's not that big a deal to expose them.
+
+However, following [official Synapse's reverse-proxying recommendations](https://github.com/matrix-org/synapse/blob/master/docs/reverse_proxy.md#synapse-administration-endpoints), we're no longer exposing `/_synapse/admin` by default.
+
+If you'd like to restore restore the old behavior and expose `/_synapse/admin` publicly, you can use the following configuration (in your `vars.yml`):
+
+```yaml
+matrix_nginx_proxy_proxy_matrix_client_api_forwarded_location_synapse_admin_api_enabled: true

+# Dynamic DNS
+
+## Setup
+
+Most cloud providers / ISPs will charge you extra for a static IP address. If you're
+not hosting a highly reliable homeserver you can workaround this via dynamic DNS. To
+set this up, you'll need to get the username/password from your DNS provider. For
+google domains, this process is described [here](https://support.google.com/domains/answer/6147083).
+After you've gotten the proper credentials you can add the following config to your `inventory/host_vars/matrix.DOMAIN/vars.yml`:
+
+```yaml
+matrix_dynamic_dns_enabled: true
+
+matrix_dynamic_dns_domain_configurations:
+  - provider: domains.google.com
+    protocol: dyndn2
+    username: XXXXXXXXXXXXXXXX

Still, for additional security, we normally leave them unexposed, following [official Synapse reverse-proxying recommendations](https://github.com/matrix-org/synapse/blob/master/docs/reverse_proxy.md#synapse-administration-endpoints).
