Find available options for initializing select2

Hello, i went to select2.org site, clicked on documentation, but i’m unable to find available options when instantiating select2.
Also on this site, it is impossible to know the “latest” release version…

Here is the list of all the configuration options (listed under “Configuration” in the left navigator): https://select2.org/configuration/options-api

The current version is shown in several places on the Installation page.
