+- Now methods which can send file to Telegram returns `tokio::io::Result<T>`. Early its could panic ([issue 216](https://github.com/teloxide/teloxide/issues/216)).
+- If a bot wasn't triggered for several days, it stops responding ([issue 223](https://github.com/teloxide/teloxide/issues/223)).
 
 ## 0.2.0 - 2020-02-25
+
 ### Added
- - The functionality to parse commands only with a correct bot's name (breaks backwards compatibility) ([Issue 168](https://github.com/teloxide/teloxide/issues/168)).
- - This `CHANGELOG.md`.

+- The functionality to parse commands only with a correct bot's name (breaks backwards compatibility) ([Issue 168](https://github.com/teloxide/teloxide/issues/168)).
+- This `CHANGELOG.md`.
 
 ### Fixed
- - Fix parsing a pinned message ([Issue 167](https://github.com/teloxide/teloxide/issues/167)).
- - Replace `LanguageCode` with `String`, because [the official Telegram documentation](https://core.telegram.org/bots/api#getchat) doesn't specify a concrete version of IETF language tag.
- - Problems with the `poll_type` field ([Issue 178](https://github.com/teloxide/teloxide/issues/178)).
- - Make `polling_default` actually a long polling update listener ([PR 182](https://github.com/teloxide/teloxide/pull/182)).

 ### Removed
