[BR22a] We conducted a systematic mapping study on API deprecation including 36 primary studies. Our analysis highlights five major gaps in research: studying remote APIs, investigating a broader range of static APIs, joining views of suppliers and clients, including humans in studies, and designing with deprecation in mind.enText/Conference Paper1617-5468
