These were never documented as officially supported but to be safe we are doing a major version bump.
- No longer works in IE8 as there is function called delete and IE8 treats that as a reserved identifier
- The source structure has changed so those utilizing NPM's ability to import from arbitrary directories ex. import DeltaOp from 'quill-delta/lib/op' will have to update their imports
- Deep copy and compare attributes and deltas
- Add
concat()method for document Deltas
compose()returns a new Delta instead of self-modifying
- Support embed being any non-string type
