Due to a bug in our release packaging scripts, the wrong version of the man pages, with the wrong license text, were copied into the MySQL Server GPL packages. The MySQL Man Pages continue to be available under GPL. The MySQL Server GPL packages will be corrected ASAP. You can read and follow the public bug here.
We apologize for the confusion this has caused. As always, please feel free to contact us, to ask about changes that you are wondering about. Reporting a bug is always a good way to communicate with us.
Have a Happy GPL Midsummer, Tomas
