Just as late December brings Christmas, late June brings the annual "release train" from the Eclipse Foundation, and this year's train features the simultaneous release of project upgrades and new projects from 39 project groups. Featuring more than 33 million lines of code based on the work of 490 developers, the Helios release on Wednesday is the largest ever from the seven-year-old release train series. Highlights include a Linux IDE package, an Eclipse Marketplace Client for accessing open source plug-in software, and improved support for JavaScript and Java Enterprise Edition 6.
