What
Claude Code keeps cost and usage statistics that include cache misses. Caching lets earlier parts of a conversation be reused so they cost less, and a miss is a request that could not reuse enough of it. A request used to count as a cache miss only when its uncached tokens passed a limit. It now counts when its uncached tokens and its recached tokens added together pass that limit.
Why
The cache-miss count and cache-miss cost in your statistics can be higher than in the previous version for the same work. Keep this in mind when you compare figures across versions.
