How to choose the API version
Use the most recent version of the API that works for your release of the data.
Version numbers are split into parts, where the first part indicates the first release of the data for which the API works, and the second and optional third parts indicate major and minor fixes respectively. The API will continue to work for subsequent data releases, until the structure of the data has changed.
For example:
Version 13.2.1 had 2 major updates, 1 minor update, and works for data releases starting from 13.0
