After over 13 months of development, 4 months of beta and nearly 1000 resolved JIRA issues, the biggest release in Atlassian history is finally here: JIRA 4 is now available! JIRA 4 introduces countless new features including a fresh new UI, completely overhauled dashboards with OpenSocial gadgets and JQL -- which is, simply put, the best way to search in an issue tracker. Best of all, every feature of JIRA 4 is now available to every user with new user-based licensing starting at $10 each for 10 users. No more Standard and Professional editions, every download of JIRA 4 has Enterprise functionality. You can earn more about the new user-based JIRA pricing here. Back to the features, let me provide a bit more detail on the new stuff: * Smart UI - A complete UI refresh introduces a slick new look and feel. Improved navigation with new quick create links in the header and project browser that remember what type of issue you created last. The improved issue browser also let's you take common actions directly from the search results. * Activity streams - View recent activity for any issue, project or user. Create custom activity streams for your JIRA dashboard or subscribe to them via RSS. * JIRA Query Language - JQL is a powerful new advanced search that makes it simple for anyone to create complex (and actually useful) searches. Add these directly to gadgets for your dashboard or setup email notifications to stay up-to-date. There's a whole lot more included in this release.
