Sometimes major releases are a big splash, sometimes they're something smaller. This is the latter kind. That said, we expect to keep this in release candidate status until Node 10 ships at the end of April. There will likely be a few more features for the 6.0.0 release line between now and then. We do expect to have a bigger one later this year though, so keep an eye out for npm@7!

BREAKING AVOID DEPRECATED

When selecting versions to install, we now avoid deprecated versions if possible. For example:

Module: example
Versions:
1.0.0
1.1.0
1.1.2
1.1.3 (deprecated)
1.2.0 (latest)

If you ask npm to install example@~1.1.0, npm will now give you 1.1.2.

By contrast, if you installed example@~1.1.3 then you'd get 1.1.3, as it's the only version that can match the range.

BREAKING UPDATE AND OUTDATED

When npm install is finding a version to install, it first checks to see if the specifier you requested matches the latest tag. If it doesn't, then it looks for the highest version that does. This means you can do release candidates on tags other than latest and users won't see them unless they ask for them. Promoting them is as easy as setting the latest tag to point at them.

Historically npm update and npm outdated worked differently. They just looked for the most recent thing that matched the semver range, disregarding the latest tag. We're changing it to match npm install's behavior.

PLUS ONE SMALLER PATCH

Technically this is a bug fix, but the change in behavior is enough of an edge case that I held off on bringing it in until a major version.

When we extract a binary and it starts with a shebang (or "hash bang"), that is, something like:

#!/usr/bin/env node

If the file has Windows line endings we strip them off of the first line. The reason for this is that shebangs are only used in Unix-like environments and the files with them can't be run if the shebang has a Windows line ending.

Previously we converted ALL line endings from Windows to Unix. With this patch we only convert the line with the shebang. (Node.js works just fine with either set of line endings.)

BREAKING SUPPORTED NODE VERSIONS

Per our supported Node.js policy, we're dropping support for both Node 4 and Node 7, which are no longer supported by the Node.js project.
