We’ll use this behavior to test if the option we want to update exists in the database. If the option exists in the database, the previous code won’t create it, so your new key won’t exist.
That way, you don’t use a lot of entries in the database, and you limit the chances to have an option with the same name used by another plugin. We retrieve the version number stored in the database, as any other option, and we compare it to the constant. To understand why, assume that you have an array as an option, with some keys.
