## 4.0.0
**Major Features and  Breaking changes in this version**

#### Improvements
- *Valid date parsing* - By default fecha will check validity of dates. Previously `2019-55-01` or `2019-01-42` would parse correctly, since Javascript can handle it. Now invalid dates will return `null` instead
- *ES Module and Tree Shaking Support* - You can now import fecha `parse` or `format` independently
```js
import {format, parse} from 'fecha';

format(...);
parse(...)
```

#### Breaking changes
- `parseDate` may return `null` when previously returned a `Date`. See improvements above, but invalid dates will return `null` now
- Change to how to set masks and i18n
Previously
```js
import fecha from 'fecha';

fecha.i18n = { ... }
fecha.masks.myMask = 'DD , MM, YYYY' 
```

New
```js
import {parse, format, setGlobalDateI18n, setGlobalDateMasks} from 'fecha';

setGlobalDateI18n({
    // ...
})
setGlobalDateMasks({
  myMask: 'DD , MM, YYYY'
});
```
