3.15.0 / 2026-09-24

<ul> <li>[CHANGE] PromQL: A range query whose <code>end</code> was not aligned to <code>step</code> caused subqueries inside it to evaluate past the parent's last actual step, inflating <code>peakSamples</code> in the query stats and against the <code>query.max-samples</code> limit, and wasting storage I/O reading samples that were never used in the result.
