## 2026-05-13 00:02:32 +0300
- Базовый коммит-ориентир: `f63f40f1eb2f`.
- Добавлен `CreateChannelBody v3` с полями `channelType (2 байта)` и `channelTypeVersion (2 байта)`.
- Добавлен текущий формат `CreateChannelBody` с полями `channelType (2 байта)` и `channelTypeVersion (2 байта)`.
- Зафиксированы типы каналов: `0=stories`, `1=public`, `100=personal`, `200=group`.
- Серверная уникальность имени канала изменена на `owner + type + name(slug)`.
- Root-канал `0` переименован в `stories` на уровне API-чтения.
