+ALTER USER 'quote_user'@'%' IDENTIFIED BY 'StrongPassword!';

+GRANT SELECT ON RFQ_LOG.qt_pricelist_items TO 'quote_user'@'%';
+GRANT SELECT, INSERT, UPDATE ON RFQ_LOG.qt_configurations TO 'quote_user'@'%';
 ```
 
 Важно:
 - не выдавайте `INSERT/UPDATE/DELETE` на `qt_pricelists` и `qt_pricelist_items`, если пользователь не должен управлять прайслистами;
-- если используется host-специфичный аккаунт (`'quote_user'@'192.168.x.x'`), назначьте права и для него;
+- если видите ошибку `Access denied for user ...@'<ip>'`, проверьте, что не осталось других записей `quote_user@host` кроме `quote_user@'%'`;
 - после смены DB-настроек через `/setup` приложение перезапускается автоматически и подхватывает нового пользователя.

+# QuoteForge v1.0.3
+
+Дата релиза: 2026-02-06
+Тег: `v1.0.3`
+Диапазон изменений: `v1.0.2..v1.0.3`
+
+## Что нового
+
+- Добавлена страница управления проектами `/projects` с:
+  - датой и временем создания проекта;
+  - сортировкой по названию и дате создания;
+  - серверной пагинацией;
+  - фильтром по автору в заголовке таблицы.
+- Добавлена отдельная вкладка `Статус синхронизации` на уровне `Алерты / Компоненты / Прайслисты`.
+- Во вкладке статуса синхронизации отображаются:
+  - пользователь;
+  - версия приложения;
+  - статус (`онлайн` или относительное время последней синхронизации).
+
+## Изменения синхронизации
+
+- Реализован heartbeat синхронизации пользователей в MariaDB: `qt_pricelist_sync_status`.
+- Добавлен API `GET /api/sync/users-status` для UI статуса синхронизации.
+- Логика онлайн-статуса рассчитана от интервала фоновой синхронизации: `5 минут + 10%`.
+- В heartbeat фиксируется версия приложения (`app_version`).
+
+## Важные исправления
+
+- Исправлено восстановление отсутствующей серверной конфигурации при push обновлений.
+- Исправлено экранирование паролей в MySQL DSN в setup.
+- Улучшена логика запуска SQL-миграций на старте при отсутствии прав/необходимости.
+- Обновлена логика пересчета прайслистов через админский price-refresh.
+
+## Миграции и совместимость
+
+Добавлены SQL-миграции:
+
+- `migrations/010_add_pricelist_sync_status.sql`
+- `migrations/011_add_app_version_to_pricelist_sync_status.sql`
+
+Релиз совместим с предыдущей веткой `v1.0.x`; новая таблица синхронизации создается автоматически.
+
+## Коммиты в релизе
+
+- `b1b50ce` Add projects table controls and sync status tab with app version
+- `6ab1e98` sync: recover missing server config during update push
+- `a1d2192` Fix MySQL DSN escaping for setup passwords and clarify DB user setup
+- `a90c07c` update stale files list
+- `e9307c4` Apply remaining pricelist and local-first updates
+- `1b48401` Use admin price-refresh logic for pricelist recalculation
+- `4a86f7b` fix: skip startup sql migrations when not needed or no permissions
