The Aikau JSDoc that Hardik has kindly provided the link to is updated with each weekly release Aikau (sourced from the GitHub project: https://github.com/Alfresco/Aikau). If you want JSDoc for a specific version then you check out the specific tagged version and manually build the JSDoc using the grunt commands provided (e.g. grunt jsdoc). This will ensure that you don't try to use widgets or features not available in the version that you're using.
