+## Final Roo Code Update: Move to Zoo Code
 
-> ### The Roo Code plugin is not going away.
+> ### Roo is back as Zoo Code.
 >
-> You may have seen the [recent announcement](https://x.com/mattrubens/status/2046636598859559114) that Roo Code hit 3 million installs and the original team is going all-in on Roomote. We know that news was hard for a lot of you. This plugin means a lot to us and to you, and we hear you.
+> This final Roo Code update helps you move your local setup to the new community-maintained Zoo Code extension.
 >
-> The good news: **a community team has stepped up to carry Roo Code forward**, and we're working with them on an official handoff so the plugin you rely on keeps getting maintained and improved.
+> To migrate, install **Zoo Code** from your extension gallery as `ZooCodeOrganization.zoo-code`, then run **Roo Code: Prepare Zoo Migration** from the command palette. Roo creates a copy-based handoff bundle under its global storage with your settings and task history while leaving your original Roo data untouched. Provider profiles and API keys are included only if you explicitly choose to include them.
 
-**What's new in this release:**
-
-- Add GPT-5.5 support via the OpenAI Codex provider.
-- Add Claude Opus 4.7 support on Vertex AI.
-- Add previous checkpoint navigation controls in chat so you can step back through prior checkpoints more easily.
