Android: VLC has been one of our favorite media players for forever. After a lengthy stint in a beta (plus some region lock annoyances), the app finally graduated to version 1.0. It's now out of beta, though releasing on time is still up for debate.
The new version adds some fixes for certain ARMv8 processors, as well as Android 5.0 fixes. What that means in layman's terms is if you have any moderate-to-extremely new device purchased in the last year, it's probably supported. Which, you know, is a key feature if you're going to call your release stable.
