Twitter for BlackBerry 10 has received an update and depending on what OS you're running, you will see a neat bunch of features. If you happen to be running OS 10.3 you will see a new feature of what is called "Night Mode". Sounds exotic but in actuality it is really a dark theme that looks a lot nicer (in my own opinion) and will help with battery life.
If you're running OS 10.2.1 you will get the general bug fixes, in line action support and landscape mode. There was a little confusion because some people were seeing the update right away and able to download it and others could see it but weren't able to download it. Now it seems that all is working properly.
Head on over to BlackBerry Word to update your Twitter for BlackBerry 10 now.
