(Yves Trudeau and Jacques Fu) Over time, software evolves and it is important to stay up to date if you want to benefit from new features and performance improvements.

(Shlomi Noach) We are pleased to release gh-mysql-rewind, a tool that allows us to move MySQL back in time, automatically identify and rewind split brain changes, restoring a split brain server into a healthy replication chain.
