Update to ojs 3.1.1.2

Sorry i am asking about the latest version of ojs. I am using ojs 3.1.1 but i see a message to upgrade to ojs 3.1.1.2. What is the upgrade in this lates version which is not available on ojs 3.1.1 and what are steps to be considered before upgrading so that i dont loose any of the previous data from my journal site.
Thanks

Hi @Alumbwage,

The release notes included with each download in docs/RELEASE give a list of new features and fixes, and the upgrade instructions are in docs/UPGRADE.
