The Eclipse Foundation just released Eclipse Photon. What is in this newest release of the popular open source IDE platform?

Updated June 28, 2018

A year ago, Eclipse Oxygen had just been released and during an interview with JAXenter, Lars Vogel, founder and CEO at vogella was already talking about his anticipation for Eclipse Photon and his expectations that Eclipse Photon would be a “usability and performance” focused release.

And the time has finally arrived! Eclipse Photon is here and it with it everything we have long-awaited!

Mike Milinkovich, the Executive Director of the Eclipse Foundation, has said in the Eclipse Foundation press release: “With new language adoption happening at a faster rate, LSP based plugins will take the Eclipse IDE’s proven extensibility to the next level. Congratulations to all of the committers, projects, and Foundation staff that made the Eclipse Photon simultaneous release possible.”

Without further ado, ladies and gentlemen, let me introduce you to the future of open source IDE’s!
