The team at Atlassian has released JIRA 3.0. It is the culmination of 6 months hard work, and is probably the largest release in Atlassian's history, with over 400 individual improvements! JIRA 3.0 contains significant new features as well as many, many improvements and bug fixes.
JIRA rocks! Perhaps this helps to explain the fact that JIRA is now used by project managers, developers, managers, testers and other staff across thousands of organisations in over 35 countries.
