Release Notes
Grok Build 1.0.63
- Memory always uses the concise MEMORY.md index of topic titles and paths, and /memory lists topics by how often Grok reads them. The [memory_v2] compact_index_enabled setting no longer has an effect
- Rex terminal support reports each open session and each running subagent as its own record, so Rex shows what each one is doing. Set children = false under [ui.notifications.program_status] to report only the main status
- grok worktree list and grok worktree show mark a worktree whose folder is missing or whose source repository moved, with a hint on how to repair it
- Command hooks accept an args list: Grok runs command as one program with those arguments and no shell, and fills hook variables such as $GROK_SESSION_ID in each argument
- Plan reviews that open while you are typing keep your text in the review notes, so a typed letter no longer triggers a plan shortcut such as approve
- Plan reviews at the end of a turn wait until you close an open /feedback dialog, question, tool prompt, or queued prompt edit
- grok -w and Ctrl+W explain that no worktree was made when you run them outside a git repository
- /fork keeps the model and effort from the parent session when Grok was started with -m or --effort
- Custom models on Chat Completions endpoints no longer fail turns with a tool schema error when MCP servers are connected
- Workflow run views hide live status text for each agent on narrower terminals, so agent names are no longer cut off
