Meta just released an update for Instagram with new features for the Collab toolset and music sharing options.

First, the Collab feature has gotten a real overhaul. You can now invite up to three friends to co-author posts, carousels, or even reels. These collaborative posts will appear on each user’s profile to maximize engagement. Both private and public accounts can be added as collaborators to a post or reel. If you have a private account, start your own post or reel and invite anyone you want. They’ll be added as long as they follow you back.

This is a big problem, because the Collab feature has been severely limited up until now, with only one co-author and a much more limited toolset. Carousels were also not available for collaboration.

Speaking of photo carousels, this feature already shows a series of your favorite photos and videos, but now you can add music to it. Meta says this is a great tool for "sharing a collection of summer memories with friends or moments from your camera roll."
