Performance and maintenance release. No API or behavior changes.

Performance

  • PostgresBucket — weighted puts insert all rows in a single statement (generate_series) instead of one INSERT per unit: ~3.4× faster, shorter EXCLUSIVE lock hold. (#296)
  • PostgresBucket — every rate's windowed count is computed in one query (COUNT(*) FILTER) instead of one round trip per rate: ~2× faster multi-rate checks. (#297)
  • SingleBucketFactory.wrap_item — inlined sync fast path (no per-acquire closures), ~23% faster wrapping. (#296)
  • Deduplicated the sync/async deadline math in _delay_waiter. (#294)

Documentation

  • README rewritten for accuracy, structure, and presentation; the outdated architecture image is replaced with a component-level Mermaid diagram (renders on GitHub and ReadTheDocs). (#293, #295)

CI

  • GitHub Actions moved off the deprecated Node-20 runtime to Node-24. (#295)
