DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.76

  • Fixed autocompact circuit breaker to stop retrying after repeated failures: "autocompact: circuit breaker tripped after N consecutive failures — skipping future attempts this session" (search for "circuit breaker tripped")
  • Prompt/memory count now only counts messages after the last compaction boundary, fixing inflated counts in long sessions (search for "compact_boundary" in UFY)
  • Tool schema discovery warning now explains why typed parameters fail and how to fix it: "This tool's schema was not sent to the API — it was not in the discovered-tool set" (search for "This tool's schema was not sent to the API")
