/**
 * A generic gateway event class representing an update of a {@link ScheduledEvent ScheduledEvent} entity.
 * 
 All events in {@link net.dv8tion.jda.api.events.guild.scheduledevent.update} package extend this event and are fired
 * when a specified field in a {@link ScheduledEvent ScheduledEvent} is updated.
 *
 *  It should be noted that {@link ScheduledEvent ScheduledEvents} are not
 * actual gateway events found in the {@link net.dv8tion.jda.api.events} package, but are rather entities similar to
 * {@link net.dv8tion.jda.api.entities.User User} or {@link net.dv8tion.jda.api.entities.channel.concrete.TextChannel TextChannel} objects
 * representing a scheduled event.
 *
 * 
Requirements

 *
 * 
These events require the {@link net.dv8tion.jda.api.requests.GatewayIntent#SCHEDULED_EVENTS SCHEDULED_EVENTS} intent and {@link CacheFlag#SCHEDULED_EVENTS} to be enabled.
 * 
{@link net.dv8tion.jda.api.JDABuilder#createDefault(String) createDefault(String)} and
 * {@link net.dv8tion.jda.api.JDABuilder#createLight(String) createLight(String)} disable this by default!
 *
 * Discord does not specifically tell us about the updates, but merely tells us the
 * {@link ScheduledEvent ScheduledEvent} was updated and gives us the updated {@link ScheduledEvent ScheduledEvent} object.
 * In order to fire a specific event like this we need to have the old {@link ScheduledEvent ScheduledEvent} cached to compare against.
