I've been looking for an Event Reference doc for Craft 3 just like what we had for Craft 2, but couldn't find one. The only events doc I found for Craft 3 is the plugin updating guide: https://docs.craftcms.com/v3/extend/updating-plugins.html#events.
Did I miss anything? Appreciate if someone can post a link here.
Also, for Craft 2 events, we used to be able to do $event->params[$paramName] to get the params passed into the events, but I struggle to find a way to do similar things in Craft 3. Any suggestions?
