The core framework of the Eclipse programming tools project and 20 of its packages will be overhauled Friday in a massive synchronized release called Europa.

Europa, with 17 million lines of code, is significantly larger than last year’s Callisto release, which had 10 projects and 7 million lines of code, said Mike Milinkovich, the Eclipse Foundation’s executive director.

Milinkovich is happy that the project still met its end-of-June deadline, the fourth time it’s done so. “One of the key values of the Eclipse development community is predictability,” he said, because many commercial and noncommercial projects rely on the tools. Next year’s project is likely to be called Ganymede, following the Jupiter-moon naming pattern.

Eclipse includes not just programming tools and “runtime” software libraries that accompany running software produced with Eclipse, but also modules for producing software that runs on everything from PCs and servers to embedded computing devices and Web browsers.
