Resolved MySQL 5.7 or better MySQL 5.6

[Dukemaster]

For the reason that my providers offers now Ubuntu Server 16.04 LTS with Plesk Onyx (64 Bit) as an default-image option.
What is recommended by You or Plesk for this environment?
Upgrading MySQL 5.5 to only 5.6 or better upgrading to MySQL 5.7?

Please could you delete this stupid question/topic. Version of MySQL is already 5.7.
I'm not able to delete the topic, only this answer which is also obsolete.
