## [unreleased]

### Added

- `#[non_exhaustive]` on `InputFile` since we may want to add new ways to send files in the future ([#49][pr49])
- `MultipartPayload` for future proofing ([#49][pr49])
- Support for `rustls` ([#24][pr24])
- `#[must_use]` attr to payloads implemented by macro ([#22][pr22])
- forward-to-deref `Requester` impls ([#39][pr39])
- `Bot::{set_,}api_url` methods ([#26][pr26], [#35][pr35])
- `payloads` module
- `RequesterExt` trait which is implemented for all `Requester`s and allows easily wrapping them in adaptors
- `adaptors` module ([#14][pr14])
  - `throttle`, `cache_me`, `auto_send` and `full` crate features
  - Request throttling - opt-in feature represented by `Throttle` bot adapter which allows automatically checking telegram limits ([#10][pr10], [#46][pr46], [#50][pr50])
  - Request auto sending - ability to `.await` requests without need to call `.send()` (opt-in feature represented by `AutoSend` bot adapter, [#8][pr8])
  - `get_me` caching (opt-in feature represented by `CacheMe` bot adapter)
- `Requester` trait which represents bot-clients ([#7][pr7], [#12][pr12], [#27][pr27])
- `{Json,Multipart}Request` the `Bot` requests types ([#6][pr6])
- `Output<T>` alias to `<<T as HasPayload>::Payload as Payload>::Output`
- `Payload`, `HasPayload` and `Request` traits which represent different parts of the request ([#5][pr5])
- `GetUpdatesNonStrict` 'telegram' method, that behaves just like `GetUpdates` but doesn't [#2][pr2]
  fail if one of updates fails to be deserialized 
- Move core code here from the [`teloxide`] main repo, for older changes see it's [`CHANGELOG.md`].
  - Following modules were moved:
    - `bot`
    - `requests` [except `requests::respond` function]
    - `types`
    - `errors`
    - `net` [private] 
  - `client_from_env` was moved from `teloxide::utils` to crate root of `teloxide-core`
  - To simplify `GetUpdates` request it was changed to simply return `Vec<Update>` 
    (instead of `Vec<Result<Update, (Value, serde_json::Error)>>`)

### Changed

- Cleanup setters in `types::*` (remove most of them) ([#44][pr44])
- Refactor `KeyboardButtonPollType` ([#44][pr44])
- Replace `Into<Vec<_>>` by `IntoIterator<Item = _>` in function arguments ([#44][pr44])
- Update dependencies (including tokio 1.0) ([#37][pr37])
- Refactor file downloading ([#30][pr30]):
  - Make `net` module public
  - Move `Bot::download_file{,_stream}` methods to a new `Download` trait
    - Impl `Download` for all bot adaptors & the `Bot` itself
  - Change return type of `download_file_stream` — return `Stream<Result<Bytes>>``,
    instead of `Future<Result<Stream<Result<Bytes>>>>``
  - Add `api_url` param to standalone versions of `download_file{,_stream}`
  - Make `net::{TELEGRAM_API_URL, download_file{,_stream}}` pub
- Refactor `Bot` ([#29][pr29]):
  - Move default parse mode to an adaptor (`DefaultParseMode`)
  - Remove bot builder (it's not usefull anymore, since parse_mode is moved away)
  - Undeprecate bot constructors (`Bot::{new, with_client, from_env_with_client}`)
- Rename `StickerType` => `InputSticker`, `{CreateNewStickerSet,AddStickerToSet}::sticker_type}` => `sticker` ([#23][pr23], [#43][pr43])
- Use `_: IntoIterator<Item = T>` bound instead of `_: Into<Vec<T>>` in telegram methods which accept collections ([#21][pr21])
- Make `MessageDice::dice` pub ([#20][pr20])
- Merge `ApiErrorKind` and `KnownApiErrorKind` into `ApiError` ([#13][pr13])
- Refactor ChatMember ([#9][pr9])
  - Replace a bunch of `Option<_>` fields with `ChatMemberKind`
  - Remove setters (users are not expected to create this struct)
  - Add getters
- Changed internal mechanism of sending multipart requests ([#1][pr1])
- Added `RequestError::Io(io::Error)` to wrap I/O error those can happen while sending files to telegram
- Make all fields of all methods `pub` ([#3][pr3])
