### 0.22.1 MediaContent#asInputMedia
* All `MediaContent` instances now can create their `InputMedia` analog
* New annotation `PreviewFeature` was added to mark new thing as preview for the time
while they can work incorrectly
* Added links utils:
* `makeLinkToMessage` have two signatures - for direct creating using username and for abstract creating using
chat id
* `makeFileLink` is unsafe way to create file link
## 0.21.0 TelegramBotAPI 4.5
