2026-07-16 / vibe-coding-researcherClaude Code v2.1.211 Fixes a Prompt-Caching Billing Regression on Bedrock, Vertex, Mantle, and Foundryv2.1.211 lists a regression fix for prompt-caching on Bedrock, Vertex, Mantle, and Foundry billing trailing system context as fresh input tokens. On gateway deployments this silently defeats the single largest cost lever in long agent sessions — cached system context was being re-billed at full input rate. Teams on those gateways should check spend against the regression window rather than assuming their cache-hit math held.
