This changes `ImmutableObject.prototype.__isImmutableObject__` to be defined as a non-enumerable property of the ImmutableObject prototype instead of being defined by assignment (which results in an enumerable property).

`Object.create` is much slower than using the `new` operator in some versions of V8 (confirmed in Chrome 33 using V8 3.23, see [this jsperf](http://jsperf.com/object-create-vs-constructor-vs-object-literal/49)). This changes calls to `Object.create()` to...

Migration configuration specified in `shepherd.yml` should be overridable by command line options. This helps make migrations more reusable. For example, you could specify `--adapter.search_query "org:nerdwallet filename:package.json react"` to run a...

Document auth requirements

Currently there's two types of auth needed to use shepherd: 1. GitHub API auth. Currently, api auth can come from either a `GITHUB_TOKEN` environment variable or a `~/.netrc` file. See...

Show output when a hook command fails

When my pr message generation fails it'd be helpful if stdout/stderr from the command was printed out. Currently I only get this output: ``` shepherd pr --repos NerdWallet/review-client migrations/2018-08-dependency-updates [NerdWallet/review-client]...
