 # Changelog
+
+## [v0.6.0-rc.1](https://github.com/block/berd/releases/tag/v0.6.0-rc.1) - 2026-08-13
+
+This release improves project chat setup and refreshes the getting-started experience.
+
+- **Multi-folder project chats:** Choose worktree behavior for each Git folder when creating a project, with clearer setup prompts, progress, and error handling when starting a chat.
+- **Message queue improvements:** Queued messages are grouped more clearly, and dismissing one no longer sends the next message unexpectedly.
+- **Experimental — Berdy onboarding:** A refreshed five-step tour now covers providers, agents, and skills. After the tour, you can start chatting with Berdy directly from Home.
+
+**Full Changelog**: https://github.com/block/berd/compare/9b88cac3f72d09bb67cd4448029cc0fe17f6ad5c...ec12897
