An update for Instagram on Android, taking it up to version 7.3.0, has been spotted and is apparently rolling out to users. This new version appears to change the process one follows to edit and filter pictures before posting them on the service.
Users of Instagram are familiar with the three steps one follows when making a new post. After selecting an image, the app gives users a chance to crop the image, then apply some filters, and finally add a caption and some other optional information to the post.
The new process takes users directly to a new screen with most of these steps combined on this single screen. The selected image itself can be swiped on to move between filters which are displayed in real time as they are selected. A small edit button is located in the bottom left corner to access the traditional editing options. A tag button is present in the bottom right corner for tagging other users. Below all of this is a slider of nearby locations that can be selected and options for cross-posting to other services. There is also an entry field for the caption.

Apparently it’s no more possible to prefill the caption field sharing an Image from a third party app.
