Hi,
"create and release a version from this column" this option is available in the Kanban board where i can be able to release a version from board itself.

In the image i have the option in the rightmost column to release.
But in the below board m not getting that option. Can any one please let me know what is the reason and how to add that release option to the board.

Please help with solutions.
Thanks,
Krithica
