@Browser Spot If you are referring to affected and fix version, the affected is the product version where a bug is found or the version of the product used by the user to request some change or new feature.
The fix version is the product version that will include the fix or new feature implementation.
Requested Version does not exists by default on JIRA and can be a custom field used on your organization.
Hi @Browser Spot - welcome to the community!
A fix version indicates the version where you plan to release a feature or bugfix to customers. I am not sure what a Requested Version is. Where do you see Requested Version? Take a look at this article. Maybe it will help.
