Postman Collections started as a simple way to save and share API requests in the early Postman client (2013), then grew into a formal JSON format with the v1 schema published in 2015. The format then stabilized as v2.0.0 and shortly after as v2.1.0 in 2017, which remains the common export/import version today.
