How can I delete a flow version in Flow Builder Winter 20 release?

In Winter 20 release Flow builder is returning a "Maximum flow versions reached error" error when attempt to save as new version.  Flow builder has a limit of 50 versions per flow.  In the past release of Flow Builder, I was able to delete the oldest versions to solve this problem.  I do not see that there is access to previous flow versions.
