1.0.0

New Stuff:

• mergeArrays option has been added to allow disabling of default array merge behavior. When disabled, an array at the same key will completely overwrite the previous array, rather than the two being merged together.
• New README! There's now a detailed table of the available options and simpler examples.

Deprecations:

• Passing arguments other than a single options object to merge is now deprecated. While currently still supported, update your code to pass an options object instead. Multiple-argument compatibility will be removed in the next release! See the README for examples of using an options object and a table of available options.

Important: This is a semver major release. Support for Node < 4 has been removed entirely to take advantage of ES6 features.
