For MySQL 5.7, one of the engineering goals is to continue to clean up and simplify code, and improve the architecture of the MySQL Server.

As part of this spring cleaning process, some features in MySQL 5.7 had a change in behaviour; for example the EXPLAIN PARTITIONS and EXPLAIN EXTENDED syntax will be enabled by default. Other features will be deprecated and may be removed; for example the InnoDB Monitor tables.

This session aims to describe the motivations behind each of these changes proposed, and how they will affect those that administrate MySQL servers.
