14 DAY TRIAL // Google has just released a new version of YouTube on Play Store without confirming any changes. Those who who already have installed the application on their Android devices (who doesn't) will probably notice an update is available for download.
If not, then it means the rollout of the update is stages, so it might take a while until it reaches your country. Unfortunately, given the fact Google did not attach an official changelog to this new version of YouTube, we can't say for sure what's new.
We must assume it only brings minor changes like bug fixes and tweaks, possibly preparing the application for major changes in future updates.
Anyway, you can now download YouTube for Android 5.3.32 for free via Google Play Store. Keep in mind the application should be fully compatible with all devices running Android 2.1 and up.
