Migration from 5.x to 6.0.0 should be smooth. Change any instance of
`env.get(target, default)` to `env.get(target).default(default)`. For example:

```js
// Old 5.x code
const emailAddr = env.get('EMAIL_ADDR', 'admin@example.com').asString()

// New 6.x compatible code
const emailAddr = env.get('EMAIL_ADDR').default('admin@example.com').asString()
```
