EPL 1.0 says, in section 7: "The Program (including Contributions) may always be distributed subject to the version of the Agreement under which it was received. In addition, after a new version of the Agreement is published, Contributor may elect to distribute the Program (including its Contributions) under the new version." The Eclipse Foundation also encourage everyone to upgrade: https://www.eclipse.org/legal/epl-2.0/faq.php#h.60mjudroo8e5 https://www.eclipse.org/legal/epl-2.0/faq.php#h.tci84nlsqpgw Unfortunately the new Secondary License option is not available to us as we're not the original copyright holders and don't have the legal power to add one. So, no GPL compatibility. Sorry.
