I'm currently using Intel Media SDK 2012 whose API version is 1.3. I notice that the latest version is 1.7 now and I want to upgrade to this version. I want to check the new features introduced from 1.3 to 1.7 version by version but I can only find the release notes for the latest version, while missing the others that starts from 1.4 to 1.6. Where can I get these documents? Thank you!
