It's frustrating how the docs constantly refer to MySQL, but make no mention of version number. This page includes a version, seemingly on accident, but because it's part of an example of using the MySQL connector I have no idea if it reflects the version currently in use or just the one that was in use when this page was written: https://developers.google.com/cloud-sql/docs/mysql-client https://developers.google.com/cloud-sql/docs/mysql-client It's showing 5.5 -- 5.6 went General Availability over a year ago, and it's not even a recent build of 5.5 at that, so you're seemingly missing out on nearly a year's worth of bugfixes and security patches. I know Google is applying a lot of custom patches to MySQL here, but I would really worry that the work they're doing to customize MySQL is causing them to lag behind the official version in terms of features and fixes.
