 # Changelog
 
+## Dendrite 0.11.1 (2023-02-10)
+
+**⚠️ DEPRECATION WARNING: This is the last release to have polylith and HTTP API mode. Future releases are monolith only.**
+
+### Features
+
+* Dendrite can now be compiled against Go 1.20
+* Initial store and forward support has been added
+* A landing page showing that Dendrite is running has been added (contributed by [LukasLJL](https://github.com/LukasLJL))
+
+### Fixes
+
+- `/sync` is now using significantly less database round trips when using Postgres, resulting in faster initial syncs, allowing larger accounts to login again
+- Many under the hood pinecone improvements
+- Publishing rooms is now possible again
+
+## Dendrite 0.11.0 (2023-01-20)
+
+The last three missing federation API Sytests have been fixed - bringing us to 100% server-server Synapse parity, with client-server parity at 93% 🎉
+
+### Features
+
+* Added `/_dendrite/admin/purgeRoom/{roomID}` to clean up the database
+* The default room version was updated to 10 (contributed by [FSG-Cat](https://github.com/FSG-Cat))
+
+### Fixes
+
+* An oversight in the `create-config` binary, which now correctly sets the media path if specified (contributed by [BieHDC](https://github.com/BieHDC))
+* The Helm chart now uses the `$.Chart.AppVersion` as the default image version to pull, with the possibility to override it (contributed by [genofire](https://github.com/genofire))
+
+## Dendrite 0.10.9 (2023-01-17)
+
+### Features
+
+* Stale device lists are now cleaned up on startup, removing entries for users the server doesn't share a room with anymore
+* Dendrite now has its own Helm chart
+* Guest access is now handled correctly (disallow joins, kick guests on revocation of guest access, as well as over federation)
+
+### Fixes
+
+* Push rules have seen several tweaks and fixes, which should, for example, fix notifications for `m.read_receipts`
+* Outgoing presence will now correctly be sent to newly joined hosts
+* Fixes the `/_dendrite/admin/resetPassword/{userID}` admin endpoint to use the correct variable
+* Federated backfilling for medium/large rooms has been fixed
+* `/login` causing wrong device list updates has been resolved
+* `/sync` should now return the correct room summary heroes
+* The default config options for `recaptcha_sitekey_class` and `recaptcha_form_field` are now set correctly 
+* `/messages` now omits empty `state` to be more spec compliant (contributed by [handlerug](https://github.com/handlerug))
+* `/sync` has been optimised to only query state events for history visibility if they are really needed
+

 If your peering connection is operational then you should see a `Connected TCP:` line in the log output. If not then try a different peer.
 
 Once logged in, you should be able to open the room directory or join a room by its ID.
+
+## Store & Forward Relays
+
+To test out the store & forward relay functionality, you need a minimum of 3 instances. 
+One instance will act as the relay, and the other two instances will be the users trying to communicate.
+Then you can send messages between the two nodes and watch as the relay is used if the receiving node is offline.
+
+### Launching the Nodes
+
+Relay Server:
+```
+go run cmd/dendrite-demo-pinecone/main.go -dir relay/ -listen "[::]:49000"
+```
+
+Node 1:
+```
+go run cmd/dendrite-demo-pinecone/main.go -dir node-1/ -peer "[::]:49000" -port 8007
+```
+
+Node 2:
+```
+go run cmd/dendrite-demo-pinecone/main.go -dir node-2/ -peer "[::]:49000" -port 8009
+```
+
+### Database Setup
+
+At the moment, the database must be manually configured.
+For both `Node 1` and `Node 2` add the following entries to their respective `relay_server` table in the federationapi database:
+```
+server_name: {node_1_public_key}, relay_server_name: {relay_public_key}
+server_name: {node_2_public_key}, relay_server_name: {relay_public_key}
+```
+
+After editing the database you will need to relaunch the nodes for the changes to be picked up by dendrite.
+
+### Testing
+
+Now you can run two separate instances of element and connect them to `Node 1` and `Node 2`.
+You can shutdown one of the nodes and continue sending messages. If you wait long enough, the message will be sent to the relay server. (you can see this in the log output of the relay server)

 No, Dendrite has a very different database schema to Synapse and the two are not interchangeable.
 
-## Should I run a monolith or a polylith deployment?
-
-Monolith deployments are always preferred where possible, and at this time, are far better tested than polylith deployments are. The only reason to consider a polylith deployment is if you wish to run different Dendrite components on separate physical machines, but this is an advanced configuration which we don't
-recommend.
-
 ## Can I configure which port Dendrite listens on?
 
 Yes, use the cli flag `-http-bind-address`.
