Well, we cant say Twitter has forgotten their Windows Phone app anymore.
The company has just released another minor update for their official Twitter client for Windows Phone, which takes the app from 220.127.116.11 to 18.104.22.168.
In the last update the app picked up a number of image-related improvements.
Unfortunately this update does not come with a changelog, but with such a small increment it is likely a bug fix or language addition.
Download it here from Windows Phone Store for free.
