Twitter has just released an update to its official app on iOS. According to its sole line of release note, the update “includes enhancements to sharing and uploading photos.” But what exactly are these enhancements?

Well, as explained by Twitter in a new blog post, the update introduces two features: photo tagging and multiple photo sharing.

Now, Twitter lets you tag people in a photo. Specifically, you can tag up to 10 people in a photo without affecting the character count in a tweet.

If you’re tagged in a photo, you’ll be notified accordingly. You can adjust notifications and choose who can tag you in the app’s settings.

Twitter now also lets you share up to four photos in a single tweet. “And now, you can also share a series of photos that automatically create a collage,” Twitter notes. “Just tap on a preview to get the full image and slide through the group.”

Compatible with iPhone, iPod touch, and iPad running iOS 6.0 or later, the new version of Twitter for iOS is available now in the App Store for free.

Note that the new features are still in the process of rolling out. So, even if you’ve already updated to the new version of the app, you may not see either or both of them.
