* __[feature] Ability to pass command CLI arguments via configuration in .yarnrc (#3033)__

    [Maël Nison](mailto:nison.mael@gmail.com) - Thu, 6 Apr 2017 13:50:52 +0100

    This PR opens the way to share configuration between multiple projects via the use of the .yarnrc files. The current design it pretty simple: it simply adds the supported options from the yarnrc file at the beginning of the command line.

     Some notes:

     - The yarnrc is currently parsed synchronously. I believe this is not an issue, since it's quite literally the very first thing we need to do when booting the application (even before the command line can be parsed), so there's really nothing we could run concurrently anyway.

     - The yarnrc is read in another file (https://github.com/yarnpkg/yarn/blob/master/src/registries/yarn-registry.js). I haven't changed how it works there, since I wanted my first draft to have as few changes as possible, but it's something that should probably be fixed so that the code only use one path to manage the yarnrc files.

* __[breaking?] `--check-files` for install/add/upgrade/check commands that verifies node_modules consistency (#3025)__

    [Konstantin Raev](mailto:bestander@gmail.com) - Tue, 4 Apr 2017 16:40:07 +0100

    This PR expands internal implementation of integrity check functionality. The yarn-integrity file now contains all the properties as exploded JSON instead of sha-1 hashed. This makes it easier to debug issues with integrity checks and installations.

    [Bryan Pfremmer](mailto:bryanpfremmer@northwesternmutual.com) - Thu, 23 Mar 2017 00:23:03 +0000

    If your ssh daemon has a banner set this currently causes yarn add to fail because it’s expecting to get an array of git shas instead of the banner. This uses the quiet option of ssh to exclude the banners for git+ssh.
