Fixed:

• Fixed a bug where builder.group(...) calls that don't add any filters could yield an invalid query. (#616)

Fixed:

• QueryBuilder's sort method now supports sorting joined models. (#580)

Fixed:

• Calling update/create/save on a Future<Model> returns the saved model rather than the unwrapped model (#579)

New:

• An optional default parameter has been added to QueryBuilder.sum(_:). This will be used when the result set of the query is zero, instead of throwing an error. (#568, #573, #571)

Fixed:

• QueryBuilder.sum(_:) now throws a more helpful error message if the result set is empty.

Fixed:

• QueryBuilder.update(_:to:) now correctly sets the updatedAt field if the model supports timestamps. (#565, #566)
