Node.js v4.2.6 Release Brief

This LTS release is the result of a buildup of regular maintenance commits.
Of note, it comes with a minor libuv upgrade and an incredible amount of documentation improvements.

NOTICE: v4.2.6 has been released to fix a critical regression in v4.2.5. It is highly suggested you use v4.2.6 instead of v4.2.5. This blog post covers both releases.

As with all releases within major version lines, minor and patch upgrades should be drop-in replacements for previous versions.
