+### v4.3.0 (2017-02-09):
+
+Yay! Release time! It's a rainy day, and we have another smallish release for
+y'all. These things are not necessarily related. Or are they 🌧🤔
+
+As far as news go, you may have noticed that the CLI team dropped support for
+`node@0.12` when that version went out of maintenance. Still, we've avoided
+explicitly breaking it and `node@0.10` so far -- but not much longer.
+
+Sometime soon, the CLI team plans on switching over to language features only
+available as of `node@4 LTS`, and will likely start dropping old versions of node
+as they go out of maintenance. The new features are exciting! We're really
+looking forward to using them in the core CLI (and its dependencies) as we keep up
+with our current feature work.
+
+And speaking of features, this release is a minor bump due to a small change in
+how `npm login` works for the sake of supporting OAuth-based login for npm
+Enterprise users. But we won't leave the rest of y'all out -- we're working on a
+larger version of this feature. Soon enough, you'll be able to log in to npm
+with, say, GitHub -- and use some shiny features that come from the integration.
+Or turn on 2FA and other such security features. Keep your eyes peeled for new
+on this in the next few releases and our weekly newsletter!
+
+#### NEW AUTH TYPES
+
+There's a new command line option: `--auth-type`, which can be used to log in to
+a supporting registry with OAuth2 or SAML. The current implementation is mainly
+meant to support npmE customers, so if you're one of those: ask us about using
+it! If not, just hold off cause we'll have a much more complete version of this
+feature out soon.

+
+#### FASTER STARTUP. SOMETIMES!
+
+`request` is pretty heavy. And it loads a bunch of things. It's actually a
+pretty big chunk of npm's load time. This small patch by Rebecca will make it so
+npm only loads that module when we're actually intending to make network
+requests. Those of you who use npm commands that run offline might see a small
+speedup in startup time.
