Node.js v5.5.0 Release Brief
This week’s stable release is 👏 Evan Lucas’s 👏 first Node release as part of the Node.js release team. 🎉
As with all releases within major version lines, minor and patch upgrades should be drop-in replacements for previous versions.

Of a total of 59 commits:
- 14 were documentation-only commits.
