• The new rejectRateLimitedCalls option in the WebClient constructor allows you to customize how you'd like to handle

  return an error with a code property set to the value ErrorCode.RateLimitedError. - thanks @aoberoi (#599)
• Automatic pagination for cursor-based pagination enabled methods: It's always recommended to perform
  pagination using the cursor and limit options directly, but if you don't pass either when calling a method, the
  WebClient will automatically iterate through all the pages and returned a merged result. - thanks @aoberoi (#596)
• The WebClient will warn when calling deprecated methods (files.comments.add and files.comments.edit) - thanks @aoberoi (#604)
