+We moved from the go+bubbletea based TUI which had performance and capability issues to an in-house framework (OpenTUI) written in zig+solidjs.
+
+The new TUI works like the old one since it connects to the same opencode server.

+## UX changes
+
+The session history is more compressed, only showing full details of the edit and bash tool.
+
+We added a command bar which almost everything flows through. Press ctrl+p to bring it up in any context and see everything you can do.
+
+Added a session sidebar (can be toggled) with useful information.
+
+We removed some functionality that we weren't sure anyone actually used. If something important is missing please open an issue and we'll add it back quickly.
