Claude Code v2.1.246 introduces a startup warning for Bash allow rules with wildcards before the subcommand and adds an Auto mode tab to /permissions for managing classifier rules.
- Fixed severe transcript slowdowns from long lines and erratic fullscreen scrolling.
- Resolved issues with background sessions failing to open due to deleted directories or npm conflicts.
- Corrected markdown rendering, MCP tool call reporting, and plugin installation errors.
- Addressed custom theme color overrides, keybinding silencing, and timezone offsets in /stats.
- Improved /cd to apply settings immediately and enhanced Bash tool latency by replaying snapshot functions.
These changes improve session stability, fix critical UI and permission bugs, and enhance performance for background and non-interactive workflows.
