[Question] v8 version of node 6.0 #5355
Node.js v6 will be using the latest stable version of V8 at the time of its release during April. We are attempting to synchronize with the V8 team to land on V8 v5.0 but because the V8 schedule is not as firm as ours and they have to deal with the variability of the Chromium release schedule there's a possibility that we may be shipping V8 v4.9 in Node.js v6, although we'd prefer to reach v5.0 if we can.
That said, we've also agreed to try some strategies to allow upgrading of V8 during the v6 Stable cycle (some time less than 6 months) depending on how difficult it is to adapt V8 to ensure that we don't break the C++ ABI/API that we export for native addons—the priority being that a compiled addon shouldn't require a recompile to run on any semver-major version of Node.js, which is historically been very difficult and mostly necessitated us sticking to a single version of V8.
