MySQL upgrade to 5.6.4 from 5.6.33 on Ubuntu I just upgraded our MySQL server from 5.5.53 by doing the following:

sudo apt-get purge mysql-server-5.5 mysql-client-5.5
sudo apt-get install mysql-server-5.6


Which got me to version 5.6.33

However, I'm looking to get to at least 5.6.4 where it appears the DATETIME datatype takes up 37.5% less space (per this article).

I can't seem to figure out / find how to upgrade from 5.6.33 to 5.6.4.  Can anyone help?

FYI - I'm running Ubuntu 14.04.  Let me know if you need any other relevant data.

Thanks in advance.
I think you are wrong.

MySQL 5.6.33 is bigger than 5.6.4

For more information look at MySQL 5.6 release note:

https://dev.mysql.com/doc/relnotes/mysql/5.6/en/

MySQL 5.6.4 released at 2011-12-20 So MySQL 5.6.33 has already DateTime feature.
