v6.4.0

NEW FEATURES

• 6e9f04b0b npm/cli#8 Search for authentication token defined by environment variables by preventing the translation layer from env variable to npm option from breaking :_authToken. (@mkhl)
• 84bfd23e7 npm/cli#35 Stop filtering out non-IPv4 addresses from local-addrs, making npm actually use IPv6 addresses when it must. (@valentin2105)
• 792c8c709 npm/cli#31 configurable audit level for non-zero exit npm audit currently exits with exit code 1 if any vulnerabilities are found of any level. Add a flag of --audit-level to npm audit to allow it to pass if only vulnerabilities below a certain level are found. Example: npm audit --audit-level=high will exit with 0 if only low or moderate level vulns are detected. (@lennym)

BUGFIXES

• d81146181 npm/cli#32 Don't check for updates to npm when we are updating npm itself. (@olore)

DEPENDENCY UPDATES

A very special dependency update event! Since the release of node-gyp@3.8.0, an awkward version conflict that was preventing request from begin flattened was resolved. This means two things:

1. We've cut down the npm tarball size by another 200kb, to 4.6MB
2. npm audit now shows no vulnerabilities for npm itself!

Thanks, @rvagg!
