With each new release comes a new deprecation. If you're using v201602 or earlier, it's time to look into upgrading. Also remember that a double sunset happened at the end of November 2016 - both v201508 and v201511 have been sunset.
As always, if you have any questions, feel free to drop us a line on the DFP API forums or the Ads Developer Google+ page.
