Upgraded the Box SDK version from 2.56.0 to 4.7.0 version.

Upgraded with the latest SnapLogic Platform release.

Enhanced the Box Write Snap with the Write empty file checkbox that allows you to write an empty file when the incoming binary document has empty data.

• Number of Retries - Changed from 0 to 3
• Retry Interval (seconds) -  Changed from 1 to 5
  

Enhanced the output view of the Box Directory Browser Snap to display the error message, Error retrieving contents of the folder with id:<Folder ID> instead of No folder exists with <Folder ID> when you enter an invalid folder ID.

• Enhanced the Box Snap Pack with the Retry mechanism that includes the following settings:
  

  • Number of Retries: Specifies the number of attempts the snap should make to perform the selected operation in case of connection failure or timeout.
  • Retry Interval (seconds): Specifies the minimum number of seconds the Snap must wait before each retry attempt.

Fixes the intermittent failure in access token refresh for the Box OAuth2 account by adopting the refreshAccessTokenIfExpired() method that checks and refreshes the access token within the last minute of its expiry.

Fixes the Box Write Snap connection retry issue by allowing the Snap to retry only when the given input is at least '1' in Number of retries field. This fix removes the Enable Staging field.

Fixes an issue with the Box Snap Pack wherein the OAuth2 token auto-refresh fails for Box accounts. The fix includes a patch released by Box to restore functionality to the "https://www.box.com/api/oauth2/token URL" of the deprecated version 1 of the Box API. 

Box recommends users to start using the endpoint in version 2 of the Box API: "https://api.box.com/oauth2/token" as seen in the blogpost here: https://blog.box.com/start-migrating-to-v2-of-the-content-api-deprecating-v1-in-december 

Fixes an issue with the Get Group Members Snap wherein the Snap is unable to return more than 100 users.

• Added a new account type, Box Service Account, which enables you to create user accounts that can only be accessed programmatically through the APIs.
• Added new properties, Number of retries and Retry interval (seconds), in the Box Write Snap to handle failed write attempts.

Pushed automatic rebuild of the latest version of each Snap Pack to SnapLogic UAT and Elastic servers.

Added the Snap Execution field to all Standard-mode Snaps. In some Snaps, this field replaces the existing Execute during preview check box.
