- Fix Api Unknown error (Can't parse entities) on message created with `utils::markdown::user_mention_or_link` if user full name contaiins some escapable symbols eg '.'
- The old dispatching system and related stuff: `dispatching`, `utils::UpState`, `prelude`, `repls2`, `crate::{dialogues_repl, dialogues_repl_with_listener}`, and `#[teloxide(subtransition)]` [**BC**].
- Move `update_listeners`, `stop_token`, `IdleShutdownError`, and `ShutdownToken` from the old `dispatching` to the new `dispatching` (previously `dispatching2`).
- Replace `crate::{commands_repl, commands_repl_with_listener, repl, repl_with_listener}` with those of the new `dispatching` [**BC**].
-`UpdateListener::StopToken` is now always `Send` [**BC**].
- Rename `BotCommand` trait to `BotCommands` [**BC**].
-`BotCommands::descriptions` now returns `CommandDescriptions` instead of `String` [**BC**].
- Update `teloxide-core` to version `0.4.5` to fix a security vulnerability. See more in `teloxide-core` [release notes](https://github.com/teloxide/teloxide-core/releases/tag/v0.4.5).
- Do not return a dialogue from `Storage::{remove_dialogue, update_dialogue}`.
- Return an error from `Storage::remove_dialogue` if a dialogue does not exist.
- Require `D: Clone` in `dialogues_repl(_with_listener)` and `InMemStorage`.
- Automatically delete a webhook if it was set up in `update_listeners::polling_default` (thereby making it `async`, [issue 319](https://github.com/teloxide/teloxide/issues/319)).
-`polling` and `polling_default` now require `R: 'static`
- Refactor `UpdateListener` trait:
- Add a `StopToken` associated type.
- It must implement a new `StopToken` trait which has the only function `fn stop(self);`
- Add a `stop_token` function that returns `Self::StopToken` and allows stopping the listener later ([issue 166](https://github.com/teloxide/teloxide/issues/166)).
- Remove blanked implementation.
- Remove `Stream` from super traits.
- Add `AsUpdateStream` to super traits.
- Add an `AsUpdateStream` trait that allows turning implementors into streams of updates (GAT workaround).
- Add a `timeout_hint` function (with a default implementation).
-`Dispatcher::dispatch` and `Dispatcher::dispatch_with_listener` now require mutable reference to self.
- Repls can now be stopped by `^C` signal.
-`Noop` and `AsyncStopToken`stop tokens.
-`StatefulListener`.
- Emit not only errors but also warnings and general information from teloxide, when set up by `enable_logging!`.
- Use `i64` instead of `i32` for `user_id` in `html::user_mention` and `markdown::user_mention`.
- Updated to `teloxide-core``v0.3.0` (see it's [changelog](https://github.com/teloxide/teloxide-core/blob/master/CHANGELOG.md#030---2021-07-05) for more)
- Remove the `reqwest` dependency. It's not needed after the [teloxide-core] integration.
- A storage persistency bug ([issue 304](https://github.com/teloxide/teloxide/issues/304)).
- Log errors from `Storage::{remove_dialogue, update_dialogue}` in `DialogueDispatcher` ([issue 302](https://github.com/teloxide/teloxide/issues/302)).
- Mark all the functions of `Storage` as `#[must_use]`.
- Support for typed bot commands ([issue 152](https://github.com/teloxide/teloxide/issues/152)).
-`BotBuilder`, which allows setting a default `ParseMode`.
- The `Transition`, `Subtransition`, `SubtransitionOutputType` traits.
- A nicer approach to manage dialogues via `#[derive(Transition)]` + `#[teloxide(subtransition)]` (see [`examples/dialogue_bot`](https://github.com/teloxide/teloxide/tree/af2aa218e7bfc442ab4475023a1c661834f576fc/examples/dialogue_bot)).
- The `redis-storage` feature -- enables the Redis support.
- The `cbor-serializer` feature -- enables the `CBOR` serializer for dialogues.
- The `bincode-serializer` feature -- enables the `Bincode` serializer for dialogues.
- The `frunk` feature -- enables `teloxide::utils::UpState`, which allows mapping from a structure of `field1, ..., fieldN` to a structure of `field1, ..., fieldN, fieldN+1`.
- Upgrade to v4.9 Telegram bots API.
-`teloxide::utils::client_from_env` -- constructs a client from the `TELOXIDE_TOKEN` environmental variable.
- Import `Transition`, `TransitionIn`, `TransitionOut`, `UpState` to `teloxide::prelude`.
- Import `repl`, `commands_repl` to `teloxide`.
- Let users inspect an unknown API error using `ApiErrorKind::Unknown(String)`. All the known API errors are placed into `KnownApiErrorKind`.
- Setters to all the API types.
-`teloxide::dispatching::dialogue::serializer` -- various serializers for memory storages. The `Serializer` trait, `Bincode`, `CBOR`, `JSON`.
- Now provided description of unknown telegram error, by splitting ApiErrorKind at `ApiErrorKind` and `ApiErrorKindKnown` enums ([issue 199](https://github.com/teloxide/teloxide/issues/199)).
- Extract `Bot` from `Arc` ([issue 216](https://github.com/teloxide/teloxide/issues/230)).
- Mark all the API types as `#[non_exhaustive]`.
- Replace all `mime_type: String` with `MimeWrapper`.
- 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)).
- The functionality to parse commands only with a correct bot's name (breaks backwards compatibility) ([Issue 168](https://github.com/teloxide/teloxide/issues/168)).
- 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)).
