+# Changelog
+
+## 3.0.0
+
+Breaking: ESM-only. `require()` no longer works.
+
+- **34 window functions** (was 18): added connes, powerOfSine, generalizedNormal, planckTaper, exponential, hannPoisson, cauchy, rifeVincent, confinedGaussian, kaiserBesselDerived, dolphChebyshev, taylor, dpss, ultraspherical, parzen, bohman
+- **Quantitative metrics**: `enbw`, `scallopLoss`, `cola`
+- **Individual files**: `import hann from 'window-function/hann'`
+- **Default + named exports**: both `import hann from` and `import { hann } from` work
+- **TypeScript declarations** included
+- **Scientific SVG plots** for all windows (time domain + frequency response)
+- Consolidated to ESM (`"type": "module"`)
+- Single `util.js` for shared helpers and utilities
+- Zero dependencies (fourier-transform is devDependency for plot generation only)
+
+### Migration
+
+```diff
+- const hann = require('window-function/hann')
++ import hann from 'window-function/hann'
+```
+
+The per-sample API `fn(i, N, ...params) → number` is unchanged.
+
+## 2.1.0
+
+- Added `apply` and `generate` helpers
+
+## 2.0.2
+
+- 18 window functions: rectangular, triangular, bartlett, welch, hann, hamming, cosine, blackman, exactBlackman, nuttall, blackmanNuttall, blackmanHarris, flatTop, bartlettHann, lanczos, gaussian, tukey
