-# OpenCode 1.0
-
-OpenCode 1.0 is a rewrite of the TUI
-
-We went from the go+bubbletea based TUI which suffered from both performance and capability issues to an in-house
-framework (OpenTUI) written in zig+solidjs.
-
-The new TUI mostly works like the old one as it's connecting to the same
-opencode server.
-
-There are some notable UX changes:
-
-1. The session history is more compressed, only showing the full details of the edit
-   and bash tool.
-
-2. We've added a command bar which almost everything flows through. Can press
-   ctrl+p to bring it up in any context and see everything you can do.
-
-3. Added a session sidebar (can be toggled) with some useful information.
-
-We've also stripped out some functionality that we were not sure if anyone
-actually used - if something important is missing please open an issue and we'll add it back
-quickly.

+title: Migrating to 1.0
+description: What's new in OpenCode 1.0.
+---
+
+OpenCode 1.0 is a complete rewrite of the TUI.
+
+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.
+

+
+## Upgrading
+
+You will not be autoupgraded to 1.0 if you are currently using a previous
+version.
+
+
+To upgrade manually, run
+```bash
+$ opencode upgrade 1.0.0
+```
