This update represents a major hardening of the Drive API surface. A wide array of parameters that were previously optional or implicitly handled are now strictly required, including fileId, revisionId, commentId, permissionId, driveId, teamDriveId, and pageToken. Developers must ensure these IDs are explicitly provided in all relevant method calls.
Additionally, many schema properties have been transitioned to read-only/immutable status. This includes sensitive or system-generated fields such as User.emailAddress, File.exportLinks, Permission.permissionDetails, and Comment.mentionedEmailAddresses. On the feature side, new OAuth2 scopes have been added, including a specific scope for Google Meet files (drive.meet.readonly).
