### 0.8.2
* Several general improvements: if an instances of an object are in the tree they will now be one instance in the resulting tree as well, also in the ES5 impl
* Always freeze data that is newly added to the draft
* Fixed [#75](https://github.com/mweststrate/immer/issues/75), don't use Symbols if not available.
