The official Twitter app for Windows 10 has received an update, though it's not entirely clear what's new. There's no changelog included with the update, so there's no official account of what it includes. However, given that the microblogging service recently rolled out algorithmic timelines, it's likely that the update is related in some way.
If version numbers are your concern, this update brings the app up to version 4.3.4. Unfortunately, this update doesn't herald the arrival of Windows 10 Mobile support, so you'll have to keep holding out for that. In any case, you can grab the latest version of the Twitter app for Windows 10 from the Windows Store link below. And be sure to shout out in the comments if you notice anything new or notable that we may have missed.
