Finally got around to trying the Zenith update. Quite a few QoL changes and some new content added since I last played. There's cosmetics, a battlepass thing with daily/weekly quests, a new tutorial and pets.
You unlock specific pets by catching them in the world a ton of times; They have a chance to escape the ball but you can reduce that by getting direct hits or throwing from long range. The higher level pets look like they require a long grind.
