stablyai/orca v1.4.200 on GitHub

Thank you so much for using Orca and for your continued support! ❤️

Please note: It usually takes 48–72 hours for a landed PR to be released (except P0+ fixes). We have many more exciting PRs and features coming in later versions!

The short version

Native chat: Claude subagent activity and Codex background tasks are now visible in chat. Completed turns show changed files, and task updates stream into the composer.

Orchestration: Worker-terminal ownership is established at creation. Startup, mobile input, and older federation coordinators have additional recovery safeguards.

Workspace & browser: Background browser tabs load on open, and creating a chat preserves the active worktree.

Product experience

Workspaces, tabs & browser

Keep the current worktree selected, and trust a newly opened browser tab to be ready when you visit it.

Agents & workflow

Native chat

The conversation gives you a much better read on what an agent did, is doing, and has delegated.
