 # Changelog
 
+## [0.9.0] -- Unreleased
+
+### Highlights
+
+- Somewhat stable end to end encryption
+  - Show the room verification status
+  - Configure Nheko to only send to verified users
+  - Store the encryption keys securely in the OS-provided secrets service.
+  - Support online keybackup as well as sharing historical session keys.
+- Crosssigning bootstrapping
+  - Crosssigning is used to simplify the verification process. In this release
+     Nheko can setup crosssigning on a new account without having to use a
+     different client.
+  - Nheko now also prompts you, if there are any unverified devices and asks you to verify them.
+- Room directory (Manu)
+  - Search for rooms on your server and other servers. (Prezu)
+  - If their topic interests you and it has the right amount of members, join
+      the room and the discussion!
+- Custom sticker packs
+  - Add a custom sticker picker, that allows you to send stickers from MSC2545.
+  - Support creating new sticker (and emote) packs.
+  - You can share packs in a room and enable them globally or just for that
+      room.
+- Token authenticated registration (Callum)
+  - Sign up with a token to servers, that have otherwise disabled registration.
+  - This was done as part of GSoC and makes it easier to run private servers for
+      your family and friends!
+
