Feature release

⚠️ It's been brought to my attention that this release contains a bug, please be aware of #211

This new release addresses a feature which has been requested by users on a number of occasions and that is multiple uploads using associations.

So now you can finally associate many uploads to a single parent. For example if you are creating a new Post entity, you can associate many Uploads to that Post, using a Posts hasMany Uploads in your table relationships.

There is a more complete example in the documentation.

Thanks to everyone who contributed code, thoughts and issues for this release.
