Right now, all the platforms and plugins require a minimum of
node 0.10 to be installed.
node 0.10 has been out of LTS  for a while now, and its maintenance period (security bug fixes) stops on Oct 2016.
node 0.12 will be out of maintenance Jan 1st 2017.
I propose an immediate deprecation of our
node 0.x support, and a migration to a minimum of
node 6.x once the deprecation period is over. The deprecation period will run for 3 months, and ends Jan 1st 2017.
node 6.x will be on active LTS Oct 2016, with
node 7.x as the current release at the same time .
node 6.x give us?
99% ES2015 (ES6) support , and
100% ES2016 (ES7) support .
Also, on Oct 1st 2016, the default
node version that people download on
nodejs.org will be
Oct 1st 2016 - deprecate use of
node 0.x. Make sure all AppVeyor/Travis CI builds still test using
node 0.x as well as
Jan 1st 2017 - Make sure all AppVeyor/Travis CI builds only test for
node 6.x. Safe to use ES6 and ES7 features in Apache Cordova. Tools and platforms will have to bump a major version.
