The Eclipse Public License (EPL) is a weak copyleft open source license maintained by the Eclipse Foundation. There are two versions of the EPL — the original EPL-1.0, which was released in 2004, and the EPL-2.0, which was published in 2017.
The EPL-1.0 has been deprecated (and the Eclipse Foundation recommends OSS contributors consider switching to 2.0), so we’ll focus primarily on version 2.0 in this blog.
