Twitter has recently released a major version of its Android application that has brought in several important new features and improvements.
However, the previous version might have included some bugs that some users experienced on their Android devices, which is why Twitter updated the application again.
The bad news is that the latest version of Twitter doesn't come with an official changelog, so we can't tell what issues have been addressed (if any) and whether or not it adds new features and improvements as well.
That being said, make sure you update Twitter for Android to the latest version in order to get rid of any bugs brought in by the previous iterations.
You can now download Twitter for Android 5.0.1 for free via Softpedia. Keep in mind that the application should be fully compatible with all devices running Android 2.1 and up.
