### v4.1.2 (2017-01-12)
We have a twee little release this week as we come back from the holidays.
#### 0.12 IS UNSUPPORTED NOW (really)
After [jumping the gun a
little](https://github.com/npm/npm/releases/tag/v4.0.2), we can now
officially remove 0.12 from our supported versions list. The Node.js
project has now officially ended even maintenance support for 0.12 and thus,
so will we. To reiterate from the last time we did this:
What this means:
* Your contributions will no longer block on the tests passing on 0.12.
* We will no longer block dependency upgrades on working with 0.12.
* Bugs filed on the npm CLI that are due to incompatibilities with 0.12
(and older versions) will be closed with a strong urging to upgrade to a
supported version of Node.
* On the flip side, we'll continue to (happily!) accept patches that
address regressions seen when running the CLI with Node.js 0.12.
What this doesn't mean:
* The CLI is going to start depending on ES2015+ features. npm continues
to work, in almost all cases, all the way back to Node.js 0.8, and our
long history of backwards compatibility is a source of pride for the
team.
* We aren't concerned about the problems of users who, for whatever
reason, can't update to newer versions of npm. As mentioned above, we're
happy to take community patches intended to address regressions.
We're not super interested in taking sides on what version of Node.js
you "should" be running. We're a workflow tool, and we understand that
you all have a diverse set of operational environments you need to be
able to support. At the same time, we _are_ a small team, and we need
to put some limits on what we support. Tracking what's supported by our
runtime's own team seems most practical, so that's what we're doing.
* [`c7bbba8`](https://github.com/npm/npm/commit/c7bbba8744b62448103a1510c65d9751288abb5d)
Remove 0.12 from our supported versions list.

#### WRITING TO SYMLINKED `package.json` (AND OTHER FILES)
If your `package.json`, `npm-shrinkwrap.json` or `.npmrc` were a symlink and
you used an `npm` command that modified one of these (eg `npm config set` or
`npm install --save`) then previously we would have removed your symlink and
replaced it with an ordinary file. While making these files symlinks is pretty
uncommon, this was still surprising behavior. With this fix we now overwrite
the _destination_ of the symlink and preserve the symlink itself.

[#10223](https://github.com/npm/npm/10223)
`write-file-atomic@1.3.1`:
When the target is a symlink, write-file-atomic now overwrites the
_destination_ of the symlink, instead of replacing the symlink itself. This
makes it's behavior match `fs.writeFile`.
Fixed a bug where it would ALWAYS fs.stat to look up default mode and chown
values even if you'd passed them in. (It still used the values you passed
in, but did a needless stat.)

### v4.1.1 (2016-12-16)
This fixes a bug in the metrics reporting where, if you had enabled it then
installs would create a metrics reporting process, that would create a
metrics reporting process, that would… well, you get the idea. The only
way to actually kill these processes is to turn off your networking, then
on MacOS/Linux kill them with `kill -9`. Alternatively you can just reboot.
Anyway, this is a quick release to fix that bug:

### v4.1.0 (2016-12-15)
I'm really excited about `npm@4.1.0`. I know, I know, I'm kinda overexcited
in my changelogs, but this one is GREAT. We've got a WHOLE NEW subcommand, I
mean, when was the last time you saw that? YEARS! And we have the beginnings
of usage metrics reporting. Then there's a fix for a really subtle bug that
resulted in `shasum` errors. And then we also have a few more bug fixes and
other improvements.
#### ANONYMOUS METRIC REPORTING
We're adding the ability for you all to help us track the quality of your
experiences using `npm`. Metrics will be sent if you run:
```
npm config set send-metrics true
```
Then `npm` will report to `registry.npmjs.org` the number of successful and
failed installations you've had. The data contains no identifying
information and npm will not attempt to correlate things like IP address
with the metrics being submitted.
Currently we only track number of successful and failed installations. In
the future we would like to find additional metrics to help us better
quantify the quality of the `npm` experience.

([@iarna](https://github.com/iarna))
#### FILE URLS AND NODE.JS 7
When `npm` was formatting `file` URLs we took advantage of `url.format` to
construct them. Node.js 7 changed the behavior in such a way that our use of
`url.format` stopped producing URLs that we could make use of.
The reasons for this have to do with the `file` URL specification and how
invalid (according to the specification) URLs are handled. How this changed
is most easily explained with a table:
<table>
<tr><th></th><th>URL</th><th>Node.js &lt;= 6</th><th><tt>npm</tt>'s understanding</th><th>Node.js 7</th><th><tt>npm</tt>'s understanding</th></tr>
<tr><td>VALID</td><td><tt>file:///abc/def</tt></td><td><tt>file:///abc/def</tt></td><td><tt>/abc/def</tt></td><td><tt>file:///abc/def</tt></td><td><tt>/abc/def</tt></td></tr>
<tr><td>invalid</td><td><tt>file:/abc/def</tt></td><td><tt>file:/abc/def</tt></td><td><tt>/abc/def</tt></td><td><tt>file:///abc/def</tt></td><td><tt>/abc/def</tt></td></tr>
<tr><td>invalid</td><td><tt>file:abc/def</tt></td><td><tt>file:abc/def</tt></td><td><tt>$CWD/abc/def</tt></td><td><tt>file://abc/def</tt></td><td><tt>/def</tt> on the <tt>abc</tt> host</td></tr>
<tr><td>invalid</td><td><tt>file:../abc/def</tt></td><td><tt>file:../abc/def</tt></td><td><tt>$CWD/../abc/def</tt></td><td><tt>file://../abc/def</tt></td><td><tt>/abc/def</tt> on the <tt>..</tt> host</td></tr>
</table>
So the result was that passing a `file` URL that npm had received that used
through Node.js 7's `url.format` changed its meaning as far as `npm` was
concerned. As those kinds of URLs are, per the specification, invalid, how
they should be handled is undefined and so the change in Node.js wasn't a
bug per se.
Our solution is to stop using `url.format` when constructing this kind of
URL.

### v4.0.5 (2016-12-01)
It's that time of year! December is upon us, which means y'all are just going to
be doing a lot less, in general, for the next month or so. The "Xmas Chasm", as
we like to call it, has already begun. So for those of you reading it from the
other side: Hi! Welcome back!
This week's release is a relatively small one, involving just a few bugfixes and
dependency upgrades. The CLI team has been busy recently with scoping out
`npm@5`, and starting to do initial spec work for in-scope stuff.

`bundledDependencies` are intended to be left untouched by the installer, as
much as possible -- if they're bundled, we assume that you want to be
particular about the contents of your bundle.
The installer used to have a corner case where existing dependencies that had
bundledDependencies would get clobbered by as the installer moved stuff
around, even though the installer already avoided moving deps that were
themselves bundled. This is now fixed, along with the connected crasher, and
your bundledDeps should be left even more intact than before!

### v4.0.2 (2016-11-03)
Hola, amigxs. I know it's been a long time since I rapped at ya, but I
been spending a lotta time quietly reflecting on all the things going on
in my life. I was, like, [in Japan for a while](https://gist.github.com/othiym23/c98bd4ef5d9fb3f496835bd481ef40ae),
and before that my swell colleagues [@zkat](https://github.com/zkat) and
[@iarna](https://github.com/iarna) have been very capably managing the release
process for quite a while. But I returned from Japan somewhat refreshed, very
jetlagged, and filled with a burning urge to get `npm@4` as stable as possible
before we push it out to the user community at large, so I decided to do this
release myself. (Also, huge thanks to Kat and Rebecca for putting out `npm@4`
so capably while I was on vacation! So cool to return to a major release having
gone so well without my involvement!)
That said...
#### NEVER TRUST AN X.0.0 RELEASE
Even though 4.0.1 came out hard on the heels of 4.0.0 with a couple
critical fixes, we've found a couple other major issues that we want to
see fixed before making `npm@4` into `npm@latest`. Some of these are
arguably breaking changes on their own, so now is the time to get them
out if we're going to do so before `npm@5`, and all of them are pretty
significant blockers for a substantial number of users, so now is the
best time to fix them.
##### PREPUBLISHONLY WHOOPS
The code running the `publish*` lifecycle events was very confusingly written.
In fact, we didn't really figure out what it was doing until we added the new
`prepublishOnly` event and it was running people's scripts from the wrong
directory. We made it simpler. See the [commit
message](https://github.com/npm/npm/commit/8b32d67aa277fd7e62edbed886387a855f58387f)
for details.
Because the change is no longer running publish events when publishing prebuilt
artifacts, it's technically a breaking / semver-major change. In the off chance
that the new behavior breaks any of y'all's workflows, let us know, and we can
roll some or all of this change back until `npm@5` (or forever, if that works
better for you).

##### G'BYE NODE.JS 0.10, 0.12, and 5.X; HI THERE, NODE 7
With the advent of the second official Node.js LTS release, Node 6.x
'Boron', the Node.js project has now officially dropped versions 0.10
and 0.12 out of the maintenance phase of LTS. (Also, Node 5 was never
part of LTS, and will see no further support now that Node 7 has been
released.) As a small team with limited resources, the npm CLI team is
following suit and dropping those versions of Node from its CI test
matrix.
What this means:
* Your contributions will no longer block on the tests passing on 0.10 and 0.12.
* We will no longer block dependency upgrades on working with 0.10 and 0.12.
* Bugs filed on the npm CLI that are due to incompatibilities with 0.10
or 0.12 (and older versions) will be closed with a strong urging to
upgrade to a supported version of Node.
* On the flip side, we'll continue to (happily!) accept patches that
address regressions seen when running the CLI with Node.js 0.10 and
0.12.
What this doesn't mean:
* The CLI is going to start depending on ES2015+ features. npm continues
to work, in almost all cases, all the way back to Node.js 0.8, and our
long history of backwards compatibility is a source of pride for the
team.
* We aren't concerned about the problems of users who, for whatever
reason, can't update to newer versions of npm. As mentioned above, we're
happy to take community patches intended to address regressions.
We're not super interested in taking sides on what version of Node.js
you "should" be running. We're a workflow tool, and we understand that
you all have a diverse set of operational environments you need to be
able to support. At the same time, we _are_ a small team, and we need
to put some limits on what we support. Tracking what's supported by our
runtime's own team seems most practical, so that's what we're doing.

##### DISENTANGLING SCOPE
The new `Npm-Scope` header was previously reusing the `scope`
configuration option to pass the current scope back to your current
registry (which, as [described
previously](https://github.com/npm/npm/blob/release-next/CHANGELOG.md#send-extra-headers-to-registry), is meant to set up some upcoming
registry features). It turns out that had some [seriously weird
consequences](https://github.com/npm/npm/issues/14412) in the case where
you were already configuring `scope` in your own environment. The CLI
now uses separate configuration for this.

### v4.0.1 (2016-10-24)
Ayyyy~ 🌊
So thanks to folks who were running on `npm@next`, we managed to find a few
issues of notes in that preview version, and we're rolling out a small patch
change to fix them. Most notably, anyone who was using a symlinked `node` binary
(for example, if they installed Node.js through `homebrew`), was getting a very
loud warning every time they ran scripts. Y'all should get warnings in a more
useful way, now that we're resolving those path symlinks.
Another fairly big change that we decided to slap into this version, since
`npm@4.0.0` is never going to be `latest`, is to make it so `devDependencies`
are included in `npm-shrinkwrap.json` by default -- if you do not want this, use
`--production` with `npm shrinkwrap`.

Fixes typo in `npm@4` changelog.
([@kimroen](https://github.com/kimroen))
### v4.0.0 (2016-10-20)
Welcome to `npm@4`, friends!
This is our first semver major release since the release of `npm@3` just over a
year ago. Back then, `@3` turned out to be a bit of a ground-shaking release,
with a brand-new installer with significant structural changes to how npm set up
your tree. This is the end of an era, in a way. `npm@4` also marks the release
when we move *both* `npm@2` and `npm@3` into maintenance: We will no longer be
updating those release branches with anything except critical bugfixes and
security patches.
While its predecessor had some pretty serious impaact, `npm@4` is expected to
have a much smaller effect on your day-to-day use of npm. Over the past year,
we've collected a handful of breaking changes that we wanted to get in which are
only breaking under a strict semver interpretation (which we follow). Some of
these are simple usability improvements, while others fix crashes and serious
issues that required a major release to include.
We hope this release sees you well, and you can look forward to an accelerated
release pace now that the CLI team is done focusing on sustaining work -- our
Windows fixing and big bugs pushes -- and we can start focusing again on
usability, features, and performance. Keep an eye out for `npm@5` in Q1 2017,
too: We're planning a major overhaul of `shrinkwrap` as well as various speed
and usability fixes for that release. It's gonna be a fun ride. I promise. 😘
#### BRIEF OVERVIEW OF **BREAKING** CHANGES
The following breaking changes are included in this release:
* `npm search` rewritten to stream results, and no longer supports sorting.
* `npm scripts` no longer prepend the path of the node executable used to run
npm before running scripts. A `--scripts-prepend-node-path` option has been
added to configure this behavior.
* `npat` has been removed.
* `prepublish` has been deprecated, replaced by `prepare`. A `prepublishOnly`
script has been temporarily added, which will *only* run on `npm publish`.
* `npm outdated` exits with exit code `1` if it finds any outdated packages.
* `npm tag` has been removed after a deprecation cycle. Use `npm dist-tag`.
* Partial shrinkwraps are no longer supported. `npm-shrinkwrap.json` is
considered a complete installation manifest except for `devDependencies`.
* npm's default git branch is no longer `master`. We'll be using `latest` from
now on.
#### SEARCH REWRITE (**BREAKING**)
Let's face it -- `npm search` simply doesn't work anymore. Apart from the fact
that it grew slower over the years, it's reached a point where we can no longer
fit the entire registry metadata in memory, and anyone who tries to use the
command now sees a really awful memory overflow crash from node.
It's still going to be some time before the CLI, registry, and web team are able
to overhaul `npm search` altogether, but until then, we've rewritten the
previous `npm search` implementation to *stream* results on the fly, from both
the search endpoint and a local cache. In absolute terms, you won't see a
performance increase and this patch *does* come at the cost of sorting
capabilities, but what it does do is start outputting results as it finds them.
This should make the experience much better, overall, and we believe this is an
acceptable band-aid until we have that search endpoint in place.
Incidentally, if you want a really nice search experience, we recommend checking
out [npms.io](http://npms.io), which includes a handy-dandy
[`npms-cli`](https://npm.im/npms-cli) for command-line usage -- it's an npm
search site that returns high-quality results quickly and is operated by members
of the npm community.

#### SCRIPT NODE PATH (**BREAKING**)
Thanks to some great work by [@addaleax](https://github.com/addaleax), we've
addressed a fairly tricky issue involving the node process used by `npm
scripts`.
Previously, npm would prefix the path of the node executable to the script's
`PATH`. This had the benefit of making sure that the node process would be the
same for both npm and `scripts` unless you had something like
[`node-bin`](https://npm.im/node-bin) in your `node_modules`. And it turns out
lots of people relied on this behavior being this way!
It turns out that this had some unintended consequences: it broke systems like
[`nyc`](https://npm.im/nyc), but also completely broke/defeated things like
[`rvm`](https://rvm.io/) and
[`virtualenv`](https://virtualenv.pypa.io/en/stable/) by often causing things
that relied on them to fall back to the global system versions of ruby and
python.
In the face of two perfectly valid, and used alternatives, we decided that the
second case was much more surprising for users, and that we should err on the
side of doing what those users expect. Anna put some hard work in and managed to
put together a patch that changes npm's behavior such that we no longer prepend
the node executable's path *by default*, and adds a new option,
`--scripts-prepend-node-path`, to allow users who rely on this behavior to have
it add the node path for them.
This patch also makes it so this feature is discoverable by people who might run
into the first case above, by warning if the node executable is either missing
or shadowed by another one in `PATH`. This warning can also be disabled with the
`--scripts-prepend-node-path` option as needed.

#### REMOVE `npat` (**BREAKING**)
Let's be real here -- almost no one knows this feature ever existed, and it's a
vestigial feature of the days when the ideal for npm was to distribute full
packages that could be directly developed on, even from the registry.
It turns out the npm community decided to go a different way: primarily
publishing packages in a production-ready format, with no tests, build tools,
etc. And so, we say goodbye to `npat`.

#### NEW `prepare` SCRIPT. `prepublish` DEPRECATED (**BREAKING**)
If there's anything that really seemed to confuse users, it's that the
`prepublish` script ran when invoking `npm install` without any arguments.
Turns out many, many people really expected that it would only run on `npm
publish`, even if it actually did what most people expected: prepare the package
for publishing on the registry.
And so, we've added a `prepare` command that runs in the exact same cases where
`prepublish` ran, and we've begun a deprecation cycle for `prepublish` itself
**only when run by `npm install`**, which will now include a warning any time
you use it that way.
We've also added a `prepublishOnly` script which will execute **only** when `npm
publish` is invoked. Eventually, `prepublish` will stop executing on `npm
install`, and `prepublishOnly` will be removed, leaving `prepare` and
`prepublish` as two distinct lifecycles.

#### NO MORE PARTIAL SHRINKWRAPS (**BREAKING**)
That's right. No more partial shrinkwraps. That means that if you have an
`npm-shrinkwrap.json` in your project, npm will no longer install anything that
isn't explicitly listed there, unless it's a `devDependency`. This will open
doors to some nice optimizations and make use of `npm shrinkwrap` just generally
smoother by removing some awful corner cases. We will also skip `devDependency`
installation from `package.json` if you added `devDependencies` to your
shrinkwrap by using `npm shrinkwrap --dev`.

[#14327](https://github.com/npm/npm/pull/14327)
Use `readShrinkwrap` to read top level shrinkwrap. There's no reason for npm
to be doing its own bespoke heirloom-grade artisanal thing here.

[#14327](https://github.com/npm/npm/pull/14327)
Treat shrinkwrap as canonical. That is, don't try to fill in for partial
shrinkwraps. Partial shrinkwraps should produce partial installs. If your
shrinkwrap contains NO `devDependencies` then we'll still try to install them
from your `package.json` instead of assuming you NEVER want `devDependencies`.

#### SEND EXTRA HEADERS TO REGISTRY
For the purposes of supporting shiny new registry features, we've started
sending `Npm-Scope` and `Npm-In-CI` headers in outgoing requests.
