I think that you will find useful the section [Install the Latest Update](https://community.denodo.com/docs/html/browse/6.0/platform/installation/postinstallation_tasks/install_the_latest_update/install_the_latest_update) from the Denodo Platform Installation Guide.
The Support Site > Downloads > Updates lists all the updates available. Each update includes a Release Notes file for each product specifying the fixes and enhancements. Also, before downloading the update file you can check the same information in the Update Details section.
Hope this helps!
