Some app updates have really short change logs, but don't let that deceive you into thinking this isn't a big deal. Tune-In Radio was updated today with only "We've fixed some bugs to improve your TuneIn experience" listed as what's new. What bugs did they fix? Well, the only one that matters to us is that they got rid of the persistent notification that plagued users running Android 4.3.
If you're scratching your head right now, here's some context. The Android 4.3 update introduced a "bug" where some applications place persistent notifications in the notification bar. These cannot be removed, even with the option in app settings. It turns out that this was completely intentional, as Android developers wanted to draw attention to apps that were inappropriately running in the background without alerting users. The hope was that app developers would be publically shamed into fixing the bad behavior. TuneIn Radio was perhaps one of the most well-known apps needing a fix, and today it's here. Win.
