+## [7.2.1] - 2026-06-19
+
+### Added
+- Two metrics helpers, `compare` for tabulating summary statistics across several
+  return series and `rolling_sharpe` for a windowed annualized Sharpe ratio.
+  Both are exported at the top level.
+- `docs/MODULES.md`, a per module guide with a verified snippet for every module.
+
+### Fixed
+- Technical indicators now load in a base install. The signals package no longer
+  fails to import when scikit-learn is absent, so the 40+ pure numpy indicators
+  (RSI, MACD, BollingerBands, and the rest) are available without any extras.
+- Hierarchical risk parity works on pandas 2 and 3. Replaced the removed
+  `pd.Series.append` call with `pd.concat` in the quasi-diagonalization step.
+- `RealizedVolatility` accepts OHLCV column names in any capitalization.
+- Resolved the top-level `VWAP` name clash. `meridianalgo.VWAP` is the execution
+  scheduler again; the volume indicator stays at `signals.indicators.VWAP`.
+- Packaging `readme` now points to `docs/PYPI_README.md` after the docs move,
+  so source builds no longer fail on a missing file.
+
+### Changed
+- Rewrote the README and the docs so every example matches the tested code.
+  Added `docs/TEST_RESULTS.md` with a full hands-on test report.
+- Removed the `examples/` folder. Short runnable snippets now live in the README
+  and `docs/MODULES.md`, with every reference updated to match.
