Yes, Apple has just released the newer iOS 16.4 Public Beta after pushing iOS 16.3.1 update to everyone, so, the new update again brings a lot of new things onboard.
From new emojis to new Face ID animations, a lot has changed, in terms of emojis here are all of them: shaking head, pink heart, blue heart, gray heart, donkey, moose, black bird, goose, wing, jellyfish, hyacinth, pea pod, ginger, fan, comb, flute, maracas, and left and right facing hand options.
The shaking head emoji has taken Twitter by storm and fans are indeed loving it. Now, Safari Web Push notifications are available but web devs have to add support for native push notifications. Much like on a mac, you can now add a website on your iOS home screen and the website will be able to send you push notifications.
Also, you have a lot of here & there updates like HomeKit Architecture Upgrade or new improvements to the Podcasts app or say new Apple Music App Profile, 5G support for Turkey and more.
