The date of the specification change to LINE Login (as stated in the November 22 post) will be postponed from December 15 to December 19. The details of the specification change as specified in the earlier post are shown below.

November 22 post:

Based on the OAuth 2.0 specification, we will add parameters [error, state] to the error response of LINE Login authentication.

These parameters will be added to the error response sent to the callback URL when the user selects cancel on the agreement screen which is displayed during the LINE Login process.

In addition, in accordance with the OAuth 2.0 specification, the errorCode and errorMessage parameters in the current error response will be deprecated and removed in the future.

2016/12/13

Whitelisting LINE domains is no longer a requirement for using the LINE SDK for iOS. As such, the documentation on whitelisting LINE domains found in the "Settings for iOS 9 or later" section has been removed.
