-The release notes below are annotated with the main breaking changes that warrant the jump to v5. Note that because this new version of Node.js is shipping with a new version of V8, you will need to recompile any native add-ons you have already installed or you will receive a runtime error when trying to load them. Use `npm rebuild` or simply remove your _node_modules_ directory and `npm install` from scratch.
