The Parsing team at the Wikimedia Foundation that develops the Parsoid service is deprecating support for node 0.1x. Parsoid is the service that powers VisualEditor, Content Translation, and Flow. If you don't run a MediaWiki install that uses VisualEditor, then this announcement does not affect you.

Node 0.10 has reached end of life on October 31st, 2016 [1] and node 0.12 is scheduled to reach end of life December 31st, 2016 [1].

Yesterday, we released a 0.6.1 debian package [2] and a 0.6.1 npm version of Parsoid [3]. This will be the last release that will have node 0.1x support. We'll continue to provide any necessary critical bug fixes and security fixes for the 0.6.1 release till March 31st 2017 and will be completely dropping support for all node versions before node v4.x starting April 2017.

If you are running a Parsoid service on your wiki and are still using node 0.1x, please upgrade your node version by April 2017. The Wikimedia cluster runs node v4.6 right now and will soon be upgraded to node v6.x [4]. Parsoid has been tested with node 0.1x, node v4.x and node v6.x and works with all these versions. However, we are dropping support for node 0.1x right away from the master branch of Parsoid. Going forward, the Parsoid codebase will adopt ES6 features available in node v4.x and higher which aren't supported in node 0.1x and will constitute a breaking change.
