Another *giant* Grok Build release from @SpaceXAI 🔥 Version 0.2.121 (2026-08-05) is live. Here are the standout changes: Features - Dashboard rows now display a short summary of what the agent did on the previous turn - Extensions modal groups items alphabetically with collapsible Skills sections - Parent agent gets reminded to keep working when a subagent runs in the background - Clients can reattach to a running session without replaying the full transcript and can close sessions explicitly - Grok no longer asks which project directory to use when launched from home or other non-project folders - /feedback opens a dedicated report box instead of dropping into prompt mode - Auto theme detection works over SSH and inside tmux - Voice and Finance tool cards render with icons and localized labels - Markdown tables reflow inside cells on narrow panes instead of clipping Bug fixes include better handling of large MCP image outputs, reliable session resumes after remote restores, correct default branch detection, and smoother cancel behavior so background tasks stop cleanly.
