+## [0.2.0] — 2026-08-17
+
+Stable release of the canonical `rewardharness` package introduced in the
+release candidate.
+
+### Added
+
+- Published the `py.typed` marker and `Typing :: Typed` classifier so type
+  checkers can consume the package's inline annotations.
+- Added dedicated Documentation, Changelog, and Issues links to PyPI metadata.
+
+### Changed
+
+- Promoted the v0.2 package, schema-v2 Library, unified CLI, and compatibility
+  adapters from release candidate to stable.
+- Hardened trusted publishing with full-history release builds, explicit GitHub
+  repository targeting, modern-pip wheel installation, and post-publish checks.
