4.x Breaking field changes

With the release of 4.0.0 the default device model was updated from Galaxy Nexus 4.x.x to a Nexus 5X device. As a result some new fields have changed values and some fields were deprecated (now returning null). The benefit of the update however far outweighs these changes, allowing for more applications to be downloaded by the tool.

Some of these changes are reflected in changes to the CLI tool https://github.com/dweinstein/node-google-play-cli/commit/efe9047bd68d0d345d69156a347e7da057e3caec. But if you don't use the CLI tool then you will need to adjust your code.

Breaking changes

details.appDetails.certificateSet returns an array of objects with certificateHash field set.

numDownloads

details.appDetails.numDownloads field now returns something like "100,000+ downloads" -- this is an upstream change from google.
