The second of the two currently-available CyanogenMod phones is receiving its 12S update today in a staged rollout. The Yu Yureka, a Micromax phone, comes just days after the OnePlus One also received Cyanogen's first release to be based on Google's Android 5.0 Lollipop platform.
If you have a Yureka but haven't been able to get the update over the air, a ZIP file with the firmware can be downloaded here (mirror), though it's quite large - nearly 650MB. If you want to see what's new, Cyanogen Inc has a... frankly pretty bare-bones description here.
Finally, if you want a flashable fastboot or boot debuggable image instead, you can find them at this link.
