NOTES.md
| # Notes | ||
| * Wildcard exports/imports wont normalise if `export default` is a non-object. See [#224](https://github.com/6to5/6to5/issues/224). | ||
| ## 3.0.0 breaking changes | ||
| * Remove `allowImportExportEverywhere` option from acorn. | ||
| * Remove this shorthand from playground. | ||
| * Remove `super()` inside non-constructors - add descriptive error message. | ||
| * Split up ES5 getter/setter transforming and ES6 property methods into separate transformers. | ||
| * Add autoindentation. | ||
| * Move `super` transformation from classes into a separate transformer that also supports object expressions. | ||
| * Remove fast transformer backwards compatibility. | ||
| * Rename let scoping transformer to block scoping. |
