Eclipse Orion 14.0

Release Date

The main deliverables for the Orion 14.0 release are a development environment that runs in the browser with a multi-user server based on a Node (server and Electron app) or Java back end.

With each of these two runtimes, the client code representing the features of Orion will be served to a supported browser and allow additional functionality to be installed client side through a plug-in framework.

Primary support is for Web programming languages, however any file type can be edited.


Orion aims to provide compatibility for plugins. Plugins written for previous versions of Orion, that only use well documented services, will continue to work in Orion 14.0.

Documented server REST API has only changed in compatible ways. Existing client code running against previous versions of the Orion server (either Java or Node) will continue to work in Orion 14.0.

No compatibility is provided within Orion server code, on either Java or Node servers.


All client side messages are externalized, and if additional language packs are present they will be used, based on the browser's language settings. Server strings are not externalized and messages from third party libraries used by Orion are not guaranteed to be externalized.
