The next Kintone update is 8th June 2018. The release also includes the following updates.

• Evaluate Record Permissions (GET /k/v1/records/acl/evaluate.json)
  This new API evaluates the API user's permissions for records and fields within an App.
  An App ID and an array of Record IDs are passed in as parameters.

• The Set Config function kintone.plugin.app.setConfig() for the Plug-in JavaScript API was returning an unrelated error message when the config key included non-ASCII characters.
  This update corrects the error message and makes it easier to understand the issue and make the needed fixes.
