release: 0.2.4

feat: the text of a picture's or a search's card folds and unfolds smoothly
feat: pictures for the assistant - the models make and edit them by themselves through the Vertex API (a new picture, or the user's attached photo, or the last picture made), with an API key in Настройки and a switch for the prompt improver; folded descriptions of pictures and searches; the name of an attached file opens or saves it; a deleted chat is wiped from the database files, attachments included

  Плашка «Поиск» даёт ассистенту искать в интернете; поисковик выбирается там же: DuckDuckGo

  или Tavily (по ключу). Если выбранный не ответил, поиск идёт через DuckDuckGo.
+  **Картинки**: если администратор задал API-ключ в «Настройки › ИИ-ассистент › Генерация изображений»
+  ([Vertex API](https://s2.x-grk.com/api/vertex/docs)), модели сами, по смыслу разговора и без плашки, рисуют картинки
+  и правят фото - то, что пользователь прикрепил к сообщению, или последнюю созданную картинку
+  (блоки ```` ```image ```` и ```` ```image edit ````, формат и качество - в первой строке; улучшение описания
+  можно отключить: `noenhance`). Картинка показывается в чате, описание в карточке сворачивается.
+  Название прикреплённого файла открывает его (или скачивает). Удаление чата стирает его содержимое, в том числе
+  текст вложений, из файлов базы; картинки хранятся на сервисе Vertex и оттуда не удаляются.
 - **Сохранённые SSH-хосты** - в окне SSH-подключения галочка «Сохранить»: хост и вход (пароль или

redtea	dd1244a169	feat: pictures for the assistant - the models make and edit them by themselves through the Vertex API (a new picture, or the user's attached photo, or the last picture made), with an API key in Настройки and a switch for the prompt improver; folded descriptions of pictures and searches; the name of an attached file opens or saves it; a deleted chat is wiped from the database files, attachments included	2026-10-18 12:12:54 +03:00
