Discontinuing authorization support for the Google Sign-In JavaScript Platform Library

Google announced the deprecation of its Google Sign-In JavaScript Platform Library, set for full retirement on March 31, 2023, urging developers to migrate to the Google Identity Services library. This transition aims to enhance user security and privacy by consolidating identity APIs into a single SDK and utilizing OAuth 2.0 for user authorization and data sharing features. The new library, which is not fully backward compatible with the older Platform Library, necessitates code modifications and explicit inclusion of the new Identity Services library for web applications using the soon-to-be-retired gapi.auth2 module and related access tokens. The migration separates authorization and authentication functionalities, providing benefits such as more secure pop-ups for authorization, increased user privacy, and forward compatibility with upcoming privacy changes in Chromium. Developers are encouraged to consult the migration guides provided and can seek technical assistance through Google's developer site and Stack Overflow.
