Release Notes

Grok Build 1.0.64

• Untrusted folders run only managed hooks from your organization. User, project, plugin, and agent hooks wait until you trust the folder. Headless sessions treat user hooks as trusted
• Worktree names typed with Ctrl+W keep Unicode letters such as café, and a name or ref that starts with - is refused
• Auto mode runs a shell command without review only when every command in it matches an allowlist entry; anything else asks first. Permission rules read each word the way bash passes it to the program
• /resume loads older sessions when you reach the last row, and shows how many sessions are loaded
• Auto mode runs make --version, cmake --version, and just --version without asking
• HTTP connections, including remote MCP servers, accept gzip, brotli, zstd, and deflate compressed responses
• Plugin install suggestions above the prompt are off when disable_plugins = true is set
• New worktrees keep tracked files that match .gitignore, and leave out files excluded only by .git/info/exclude or core.excludesFile
• A new session that fails to start puts what you typed back in the prompt you return to, instead of losing it
• Web search works from the first turn of a session, and in subagents, when the search model signs in through an external auth provider
• grok -w, grok worktree create, worktree forks, and subagent worktrees refuse up front with the sandbox refusal message when the sandbox profile does not allow creating worktrees
• Worktree options are hidden in /fork, /new, and the Welcome screen when the sandbox profile does not allow creating worktrees
• A worktree name you type that is already taken is refused instead of getting a numbered suffix, and a name whose folder you deleted by hand can be used again
• Grok on macOS without a GUI session, such as over SSH, no longer hangs on its first modifier-key check
• Custom models on the Responses API keep the turn going when a web search call starts without an action
• Shell commands run correctly on zsh when your startup files alias grep or replace run-help
• Voice dictation preview grows the prompt as you speak and keeps the newest words in view
