Just a couple of days after the CyanogenMod 12 update hit the shores of the OnePlus One here in India, the Yu Yureka, another device powered by CyanogenMod OS has been updated with the goodness of Lollipop. Yu had been teasing the update for a while now on Social Media and looks like it was the certification signing which held up the release for CM 12 here in India. Yu clearly mentioned in their press release that the rollout will be in the form of phases which would see all the devices receive the update in the next three days.
The update will take the Yu Yureka to Android version 5.0.2, which by the way is not the latest Android build, with it being Android 5.1, though there has been no significant news on whether Android 5.1 would be released at all for the devices that are running CyanogenMod ROMs.
The update is obviously OTA so you will need to check for the same under Settings and About device where you can look for the update. Once it is available you will have to accept that you are in and the update will be downloaded. You get all the goodness of Android L on your device, though in addition you also get the new CyanogenMod E-Mail as well as a new Theming app from Cyanogen when you update to CM 12.
