TL;DR
- Nothing actionable today. 2.1.109 is a single cosmetic tweak to the extended-thinking indicator, skip unless you want the visual. (more below)
New in 2.1.109
2.1.109 (April 15, 2026)
- Improved the extended-thinking indicator with a rotating progress hint
Notes
2.1.109 continues the thinking-indicator polish that started in 2.1.107. 2.1.107 shortened the delay before the hint appears; 2.1.109 adds a rotating message once it does. Worth tracking only because it suggests Anthropic is actively iterating on this surface, not because either release changes anything you depend on.
