Dependency versions in package.json

See the NPM docs and semver docs:

• ~version “Approximately equivalent to version”, will automatically update you to all future patch versions that are backwards-compatible, without incrementing the minor version. ~1.2.3 will use releases from 1.2.3 to < 1.3.0.

• ^version “Compatible with version”, will automatically update you to all future minor/patch versions that are backwards-compatible, without incrementing the major version. ^1.2.3 will use releases from 1.2.3 to < 2.0.0.

See Comments below for exceptions, in particular for pre-one versions, such as ^0.2.3 > https://stackoverflow.com/a/22345808
