too many 1.*.* unreleased versions on the JIRA

[Sergey Shelukhin]

On the JIRA, we currently have 1.1.0 marked as unreleased even though
1.2.0 is released (and 1.1.1 is also present); then, we have both 1.0.1
and 1.0.2, plus 1.2.1 and 1.2.2 showing in unreleased.
I poked around and cannot see where this can be changed. Release managers
for respective releases should probably clean this up, anyway :)
