How to do dynamic parameter with v2.315

I upgraded to the latest version of Jenkins - my old server has a dynamic parameter but when I add parameter in the new version I do not see dynamic parameter as an option. How do I do this with the current version?

where do you not see this?

did you update the plugin as well?

I figured out my issue - with the new version I just used string parameter and it worked fine since Jenkins automatically updates the build number and later in the script we update the assembly version.
