JetBrains Announces General Release of Flagship IntelliJ IDEA 4.5 Java IDE

Expanded Productivity Features Optimize Code, Prevent Errors at All Stages of Development

July 27, 2004

Prague, Czech Republic, July 27, 2004 – JetBrains™, Inc., creators of intelligent application development tools, today announced the general availability of IntelliJ™ IDEA 4.5, the newest version of its award-winning Java™ IDE (Integrated Development Environment). The new release features enhanced code inspection and powerful, on-the-fly code analysis, full Java SDK 1.5 support, plus a host of new and extended features to increase the productivity of developers at all skill levels.

IntelliJ IDEA 4.5 features include expanded ability to find and correct errors before they leave the screen and enter an application’s development cycle. Preempting errors allows Java developers to write better code faster and makes their applications more stable and polished right from the earliest stages.

“Our enthusiastic users include world-class developers who increasingly proselytize for IntelliJ IDEA inside their organizations,” said Eugene Belyaev, president and chief technology officer. “As a group, they set very high standards and have consistently helped us meet their expectations by contributing to IntelliJ IDEA’s continuing evolution. We keep pace with their needs only through extensive give-and-take that keeps us flexible and often presents wonderful challenges.”

Widely recognized as the industry leader in automated code optimization, IntelliJ IDEA 4.5 introduces such innovative coding functionality as Locate Duplicates and Analyze Dependencies. A code Productivity Guide helps developers expand their own capabilities so they become more productive on a wider range of projects, increasing their professional value to their organization.
