v1.0.63

1.0.63 — 2026-10-17

Breaking Changes

• 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.

Features

• 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.

Bug Fixes

• Plan reviews that open while you are typing keep your text in the review's 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 parent session's model and effort when Grok was started with -m or --effort.
• Custom models on Chat Completions endpoints outside xAI no longer fail turns with a tool schema error when MCP servers are connected.
• Workflow run views hide each agent's live status text on narrower terminals, so agent names are no longer cut off.
