The WS282 release contains two model changes, described in more detail here:
Antibody class model changes for WS282
Summary: We assigned WBAntibody IDs to Antibody objects, we need to store the current name in a public_name tag. We also decided to get rid of Possible_pseudonym and Other_animal. This clean up work is a result of the alignment of the antibody class with other MODs at Alliance. The current info for Possible_pseudonym and Other_animal has been moved to the remarks in a structured way.
Changes to the model:
Add Public_name Remove Possible_pseudonym Remove Other_species
