Which version of Confluence is compatible with Apache Tomcat 9.0.117?

We are currently running Confluence Data Center version 9.2.19, can you confirm which Confluence version is compatible with Apache Tomcat 9.0.117?

Hi @Mei-Fang Chang

Welcome to the Atlassian community! I would look into the following versions:

Confluence 9.2.26 or later: As 9.2 is a Long Term Support (LTS) release, Atlassian typically updates the bundled Tomcat in subsequent bugfix versions.

Confluence 10.2.10 or later: These are the most recent releases as of late April 2026 and are the most likely to include the latest Tomcat security patches.

While it is technically possible to replace the Tomcat binaries in your installation directory, Atlassian strongly discourages this and I never did it.
