This tag is for discussing platform-wide changes to StackExchange, especially how they impact the MathOverflow site.

As MathOverflow runs on the StackExchange platform, and we do not control the software, sometimes there are changes that may need discussing, how they impact MathOverflow, or if and how a response should be made. MathOverflow has a special agreement with StackExchange, so we are in a different position to the rest of the sites on the platform, and in principle the impact of large changes could brush up against this special agreement in an unexpected way.
