### Improvements
__This version involves automatic migration of AUTH-related data. Relevant users are advised to review the data migration rules and upgrade at their discretion.__
* Modularization of AUTH Functionality

    * Supports global user management with new user authorization approval

    * No longer supports multi-factor authentication scenarios
    * Data Migration Rules
        * Original Custom AUTH Rules
            * Rules configured with "Application" parameter will be migrated to specified applications and automatically enable AUTH for those applications
            * Rules without "Application" parameter will be migrated to apply to all applications and automatically enable AUTH for all applications
            * No rule migration will occur for applications with AUTH already enabled
        * Original Identity Sources
            * Only active identity sources will be migrated; for GitHub, only valid users will be migrated
            * After migration, users will automatically be configured with application authorization based on original associations
