Where to find the substantive change list

The full set of additions, changes, and fixes for this release is documented in CHANGELOG.md under the ## [3.0.0] — 2026-05-20 heading, which folds in the two thematic threads that had previously been tracked as separate [Unreleased] blocks:

• Public documentation overhaul — new wiki/ directory (9 pages) and the .github/workflows/wiki-sync.yml publishing workflow, plus the README header rewrite.
• Mypy remediation (Phases 0–4) — 104 mypy errors → 0; full-scope mypy src/puma/ enforced in CI; supporting refactors documented in docs/maintenance/baseline-2026-05.md.

Reconciliation note (post-release)

This file is added as part of the Sprint 11' reconciliation work (2026-05-24). The release itself was published on 2026-05-20; this file brings docs/RELEASES/ in line with the GitHub release inventory that already existed at that time.
