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)

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

certificateHash

details.appDetails.certificateHash - now returning an empty array as it is replaced by certificateset

certificateSet

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.
