Coverage. Odoo 16 to 17 and 17 to 18 compare Community modules only (the Enterprise 16 and 17 sources are not available to us). Odoo 18 to 19 and 19 to 20 include Community and Enterprise modules. Everything here comes from a static read of the Odoo source code: a field counts as removed only when no parent model, mixin or delegated model still provides it. Fields created dynamically at run time can be missed, and entries we could not confirm are marked as low confidence.
