 # История изменений документации блокчейна
 
+## 2026-07-31 17:22:07 +0400
+- Базовый коммит-ориентир: `05bd9f5`.
+- Уточнён UI вложений: превью последнего сообщения в списке каналов скрывает технические attach-блоки, карусель не показывает неактивные стрелки на краях, обычный файл отображается компактной кликабельной полоской без `txId`; формат attach-блока не изменён.
+
 ## 2026-07-31 17:13:26 +0400
 - Базовый коммит-ориентир: `60ab476`.
 - Уточнён UI журнала загрузок Arweave: статус доступности перенесён в начало второй строки плитки, верхняя панель закреплена как fixed-полоса вне прокрутки, в меню добавлен пункт `Добавить файл`, меню закрывается при клике вне него; формат attach-блока не изменён.
