What's new in Claude Code v2.1.109

A one-bullet polish release. Default filter would have skipped this; published per explicit override.

Live thinking progress hint

Why: The previous static "thinking…" indicator gave no signal of progress, so during long extended-thinking passes you couldn't tell if Claude was still working or quietly hung.

What: Adds a rotating progress hint to the extended-thinking indicator, so the visual updates while the model reasons rather than sitting frozen.

How: Automatic — no user action required. Works in any session with extended thinking on (the default); press Ctrl+O to also see the underlying reasoning text in verbose mode.

Hosts: Alex Chen & Sarah Kim · Generated from the official Claude Code CHANGELOG.
