I have been using selec2 version 4 with ajax option. And I want to set a selected value, as recommended in the guideline, by adding new Option element.
A problem I have is that I do not know when to add the new option because the event select2-loaded does not seem to exist in the latest version of select 2.
Can you please let me know in what way I can know the moment when data has finished loading from the server and has finished setting up, so I can add a new option to it?
Thank you.

The Option element you mention is created by calling the Option() constructor which then constructs a HTMLOptionElement. So basically you are just adding to your DOM and don't need to do it in any select2 event. Instead just do it on document load.
Here's a very basic example of what it could look like:
$(function () {
$('#element-to-select').select2();
var option = new Option('text', 'value', true, true);
$('#element-to-select').append(option).trigger('change');
}
Note that we are calling .trigger('change') to report the change to select2 as documented here.
