Claude Code v2.1.220 Landed 18 Hours After v2.1.219 as a Pure Reliability Patch
Havoptic·low signal
Havoptic's tracker records v2.1.220 shipping 18 hours and 53 minutes after v2.1.219 on July 24, described only as "bug fixes and reliability improvements," with a 0.8 kB bundle decrease and changes to the prompt-token and system/tools ratio. Same-day follow-up releases after a default-model swap are worth noting as a signal: pin your version if you run Claude Code headless in CI, because the day-of-model-change build is not the one you want baked into a scheduled pipeline.
