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
- /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
