Release Notes

Grok Build 1.0.52

• Added support for OSC 7501 and the Rex terminal
• Expanded tool-call groups stay expanded as new calls join them, and Ctrl+E expands or collapses thinking faster in long transcripts
• Project hooks in a repository subfolder load when you launch inside that folder
• HTTP hooks to localhost work, and bad hook URLs are reported at load time
• Command status-line scripts see the current turn prompt ID and start time while the turn is active
• /model switches that fail no longer change the footer or the saved default model
• Export and copy refuse to overwrite an existing file, and show a clear message
• Shell commands no longer keep running after you quit grok, or after grok receives a signal
• Approval cards for background subagents no longer disappear when the parent turn ends
• grok worktree rm and gc no longer delete a worktree that an open session is using
• Pasted images over 50 MB are rejected with a clear message instead of being dropped silently
• grok -p --effort warns when the model ignores the flag, and refuses invalid effort levels
• Approval notifications name the session that needs approval
• grok worktree rm refuses to delete git repositories, .git folders, or any directory grok did not create
• grep and list_dir report a clear error when a search times out or fails, or the folder cannot be read, instead of returning no results
• Cancelled terminal commands show the command that was stopped
• Wrapped URLs in prompts and quotes link to the complete address
• Restarting after a model switch no longer reverts to the previous model
• Long tool turns that include PostToolUse hook output compact instead of hitting the prompt length limit
• Headless prompts that start with a byte-order mark no longer send that mark to the model, and no longer break JSON prompt files
• MCP tool replies that contain invalid characters no longer cause the call to time out
• Context overflow errors trigger automatic compaction instead of failing the turn
• Inline tags in agent replies no longer break line layout
• /workflow stop picks the correct live run
• Auto-compaction stops after three context refills in a row instead of looping
• Minimal mode shows the permission prompt instead of a hidden plan or cancel panel when both are present
• Approval cards close the block viewer so the card is visible
• The in-session resume picker matches the ungrouped layout on the welcome screen when that layout is configured
