Spitfire 0.10.0 release notes
Released: 2026-10-03
- Comparative runs: per-step p50, p95 and p99 differences now come with a confidence interval (bootstrap, 95% by default; 90%, 95% or 99% in the comparison dialog), e.g. "+27% (±3%)". The error-rate difference uses a two-proportion test. When an interval crosses the acceptable-difference threshold the step is "inconclusive" and a longer run is suggested; the overall verdict is better, no difference, worse or inconclusive. The comparison page explains how to read the results.
- The comparison page is tidier: in the step and stage tables p95 sits in one cell ("219 → 268 ms"), the difference and its confidence interval stacked, p50 and p99 in a row's details. Rows that mix steps of very different latency (whole run, stages) show no p50 interval. In the comparison dialog arm A starts on the latest normal run's environment, and numbers follow the UI language.
