   `edit_message_caption`, `edit_message_media` and `edit_message_reply_markup`) are split into common and inline
   versions (e.g.: `edit_message_text` and `edit_inline_message_text`). Instead of `ChatOrInlineMessage` common versions
   accept `chat_id: impl Into<ChatId>` and `message_id: i32` whereas inline versions accept
   `inline_message_id: impl Into<String>`. Also note that return type of inline versions is `True` ([issue 253], [pr 257])
- `ChatOrInlineMessage` is renamed to `TargetMessage`, it's `::Chat`  variant is renamed to `::Common`,
   `#[non_exhaustive]` annotation is removed from the enum, type of `TargetMessage::Inline::inline_message_id` changed
   `i32` => `String`. `TargetMessage` now implements `From<String>`, `get_game_high_scores` and `set_game_score` use
   `Into<TargetMessage>` to accept `String`s. ([issue 253], [pr 257])
- Remove `ResponseResult` from `prelude`.

- Replace all `mime_type: String` with `MimeWrapper`.

### Fixed

- Now methods which can send file to Telegram return `tokio::io::Result<T>`. Before that it 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`.

### 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

- [either](https://crates.io/crates/either) from the dependencies in `Cargo.toml`.
- `teloxide-macros` migrated into [the separate repository](https://github.com/teloxide/teloxide-macros) to easier releases and testing.

## 0.1.0 - 2020-02-19

### Added
- This project.
