Buzz, a Javascript HTML5 Audio library

# Buzz, a Javascript HTML5 Audio library

## CHANGE LOG

### Buzz 2.0.0 2026-02-17

**Major Release - Breaking Changes**

#### Promise Support
- Add Promise support to `fadeTo()`, `fadeIn()`, `fadeOut()`, and `whenReady()`
- Maintain 100% backward compatibility with callback pattern
- Return Promise when no callback provided, otherwise return `this` for chaining
- Support async/await syntax

#### Modern JavaScript
- Modernize codebase with ES2015+ syntax
- Add TypeScript definitions (`buzz.d.ts`)

#### Build & Distribution
- Simplify build to 2 files: `buzz.js` (ES Module) + `buzz.min.js` (UMD minified)
- Remove `buzz.esm.js` (replaced by `buzz.js`)
- Modern import support: `import buzz from 'buzz'`
- Legacy CDN support: `<script src="buzz.min.js"></script>`
- Source maps included for minified version

#### Testing
- Replace Jasmine with lightweight Puppeteer-based tests
- Comprehensive tests
- Headless browser testing

#### Breaking Changes
- Remove Jasmine test framework
- Change build output: no more `buzz.esm.js`, use `buzz.js` instead
- `buzz.js` is now ES Module format (use `buzz.min.js` for UMD/CDN)
- Require ES2015+ browser support

#### Migration Guide
```javascript
// Before (callbacks only)
mySound.fadeIn(1000, function() {
    console.log('Done!');
});

// After (still works + Promise support)
// Option 1: Callbacks (backward compatible)
mySound.fadeIn(1000, function() {
    console.log('Done!');
});

// Option 2: Promises
mySound.fadeIn(1000).then(() => {
    console.log('Done!');
});

// Option 3: async/await
await mySound.fadeIn(1000);
console.log('Done!');
```
