Hello team
Im reading an atlassian doc
I find this :
If you are using a Kanban board, you cannot use the Release Hub to
check the status of an unreleased version. The Release Hub on
Kanban boards only shows released versions.
I do not understand because i see realeased and unreleased version in kanban project , what does it mean ?

Thnak you very much
regatds
