Fastest way to create new versions for projects in Jira

1. using the REST API

curl -i -H "Content-Type: application/json" 
-X POST -d '{"description": "An excellent version",
             "name": "New Version 1",
             "userReleaseDate": "2014-05-23",
             "project": "PROD",
             "archived": false,
             "released": true}' 
-u username:password http://<jira.host>/rest/api/latest/version

2. using Jira CLI from bobswift.atlassian.net

./jira.sh --action addVersion 
          --project PROD 
          --description "Another excellent version" 
          --version "New Version 2" 
          --date "23.05.2014 10:00"
