+Because of an update to the database structure, users who upgrade from a commit BEFORE 4c673956959532d61b8f9ba0be3191a054b4371a **MUST** perform the following SQL on the database:
+```sql
+ALTER TABLE `judge_state` ADD `is_public` TINYINT(1) NOT NULL AFTER `compilation`;
+UPDATE `judge_state` JOIN `problem` ON `problem`.`id` = `judge_state`.`problem_id` SET `judge_state`.`is_public` = `problem`.`is_public`;
+ALTER TABLE `syzoj`.`judge_state` ADD INDEX `judge_state_is_public` (`id`, `is_public`, `type_info`, `type`);
