Added `/color` command for all users to set a prompt-bar color for your session
Added session name display on the prompt bar when using `/rename`
Added last-modified timestamps to memory files, helping Claude reason about which memories are fresh vs. stale
Added hook source display (settings/plugin/skill) in permission prompts when a hook requires confirmation

Improved startup performance on macOS non-MDM machines by skipping unnecessary subprocess spawns

Suppressed async hook completion messages by default (visible with `--verbose` or transcript mode)

Fixed the Claude Code header not updating the displayed model name after switching models with `/model` or Option+P
Fixed session crash when an attachment message computation returns undefined values
Fixed Bash tool mangling `!` in piped commands (e.g., `jq 'select(.x != .y)'` now works correctly)

Fixed token estimation over-counting for thinking and `tool_use` blocks, preventing premature context compaction
Fixed corrupted marketplace config path handling
Fixed `/resume` losing session names after resuming a forked or continued session
Fixed Esc not closing the `/status` dialog after visiting the Config tab
