Major changes: - Don't generate a patch, instead generate the merged object so it can be used with PUT - Separate tree parsing logic to collate items in a list from the delete / merge / replace / add logic when merging - Use openapi for merge strategy metadata so it works with extensions and version skew - Support multi-field mergekeys when merging lists - Support replace strategy for maps - Reduce complexity of generating order when merging lists - keep the locally defined order and append remote only-items Continue to support: - Explicitly setting fields to null - Merging lists of primitives - Don't randomize ordering when merging lists TODO: - Retain keys - Conflict detection
