A better strategy is to 1. Audit the current master branch and look at the patches that have been floated since the last major V8 update. 1. Replace the copy of V8 in Node.js with a fresh checkout of the latest stable V8 branch. Special care must be taken to recursively update the DEPS that V8 has a compile time dependency on (at the moment of this writing, these are only trace_event and gtest_prod.h) +1.
