## [1.0.0-rc.3] - 2026-02-04

⚡ Remove Unnecessary Default Export Assignment

- Eliminates redundant variable assignments when exporting default values
- Reduces output bundle size and improves code clarity
```js
// index.js
var x = 42;
export default x;

// Before
var x = 42;
var entry_default = x;
export { entry_default as default };

// After
var x = 42;
export { x as default };
```

🐛 Avoid Unnecessary Facade Chunks

- Keep user-defined entry modules in their own chunks
- Reduces HTTP round trips and improves startup performance

```js
// main.js (entry module)
import { a } from './lib.js'
console.log(a)

// lib.js
export * from './counter.js'

// counter.js (entry module)
export const a = 100

// Before
dist/
├── main.js           → import { a } from './counter-chunk.js'; console.log(a)
├── counter.js        → export { a } from './counter-chunk.js' // ❌ facade chunk
└── counter-chunk.js  → export const a = 100

// After
dist/
├── main.js    → import { a } from './counter.js'; console.log(a)
└── counter.js → export const a = 100
```
