Updating the plugin's project
#You'll need to release the current version of the project in JIRA and move any unfinished issues for the project to a later version. Here's how:
Go to the project page in JIRA.
Click on Administer Project.
Under Versions, click on Manage versions.
From this screen, choose "release" for the version that you just created. Make sure the date is correct, and move any remaining open issues to the next unreleased version.
