What version of Tomcat is packaged with Confluence?

[Branden Loizides]

Is there a way to determine which version of Tomcat is bundled with a Confluence release? I can't find that information in the release notes.

We want to upgrade Tomcat to 9.0.71, but we want to determine which release of Confluence, if any, ships with that version. 

Thank you!

Be aware that you probably do not want to upgrade your Tomcat.  The least damage it will do is just "you are now unsupported",, but is not unknown for Atlassian software to stop working when on the "wrong" Tomcat.  I very strongly recommend that you do not try to change the Tomcat, just stick with the supported version.
