Commits from serum after 29 Aug

[KirillLykov]

It looks like 3 commits which were added to serum after 29 Aug were not added to openbook (https://github.com/project-serum/serum-dex/commits/master).
Could you clarify if it is for a reason or just two forks diverged?

What was mentioned in the telegram group.. the last 3 commits are just merged and not audited. It was forked from that commit because serum mainnet was on that commit.
