The database upgrade is carried out in BigPicture.
Do I have to manually make any changes?
The whole process is fully automated, and you don't have to change the version of your database (if your Jira database works, our plugin's database will work as well).
What does the 'review all changes' link refer to?
The message you have received provides only information about data structure changes in our tables.
In order to avoid any misunderstanding, we display information about the plugin database schema version that will make the whole process more transparent and intuitive for our customers.
