This document is OpenRTB version 2.5 released in November of 2016; this is the culmination of the working group efforts and can be found at: [http://www.iab.com/openrtb](http://www.iab.com/openrtb)  \nAbout the IAB Technology Lab  \nThe IAB Technology Laboratory is a nonprofit research and development consortium charged with producing and helping companies implement global industry technical standards and solutions. The goal of the Tech Lab is to reduce friction associated with the digital advertising and marketing supply chain while contributing to the safe growth of an industry.  \nThe IAB Tech Lab spearheads the development of technical standards, creates and maintains a code library to assist in rapid, cost-effective implementation of IAB standards, and establishes a test platform for companies to evaluate the compatibility of their technology solutions with IAB standards, which for 18 years have been the foundation for interoperability and profitable growth in the digital advertising supply chain.  \nThe OpenRTB Work Group is a working group within the IAB Technology Lab.
