## 0.17.0

Thanks to https://github.com/compressed this release has a large amount of
important fixes and breaking changes. 

- Updates to support new `slack-api` version and remove dependencies on openssl `0.7.x` and hyper
`0.9.x`.

### Breaking Changes

- Replaced `websocket` with `tungstenite`. This change moves from `openssl` to `native-tls`.
- Updated to `slack-api` version `0.16.0`. This changes many of the re-exported types
from the `slack-api` crate.
- Replaced `rustc_serialize` with `serde`. This change was needed because the new `slack-api` uses
`serde`.
- Replaced `hyper` with `reqwest`.
- Removed `on_ping` from `EventHander`. Websocket pings are handled internally.
- `EventHander::on_event` passes in the `Event` directly. Any errors are logged using the `log`
crate. The raw json string argument has been removed.
- Removed `WsMessage::Ping` variant.
- Removed `Error` variants: `Error::JsonDecode` and `Error::JsonEncode`.
- All `Sender` related functions have been moved directly to `Sender`. `RtmClient::Client::sender()`
gives a reference to the `Sender`.
- The following `RtmClient` functions have been **removed**:
  - `post_message`, `update_message`, `delete_message`
  - `mark`
  - `set_topic`
  - `set_purpose`
  - `add_reaction` replaces `add_reaction_file` and `add_reaction_file_comment`
  - `im_open`, `im_close`, `im_history`, `im_list`, `im_mark`
  - `channels_history`
  - `get_name`
  - `get_id`
- Some `Event` variants are now inside a `Box` for performance reasons (see:
https://github.com/Manishearth/rust-clippy/wiki#large_enum_variant).
- `Event::MessageSent` and `Event::MessageError` expose new interior structs: `MessageSent` and
`MessageError` respectively.

## 0.16.0
- Retry receive message on EAGAIN (jwilm) (#61)
- Change type signatures of handlers to take Event instead of &Event (pinkisemils) (#62)
- Add send typing api and cleanup get_channel_id (vampolo) (#65)

## 0.15.0
- Add async message sending API thanks to https://github.com/jwilm

## 0.14.0
- Update dependencies thanks to https://github.com/jgulotta
- Update usage information for example thanks to https://github.com/wezm

## 0.13.0
- Thanks to https://github.com/squidpickles and https://github.com/dten respectively: add unnoficial events to handle message sending success and error, and add timeout on the rtm sockeckt.

### Compatibility Changes
- Two new Events: `MessageSent` and `MessageError`
- The RtmClient now has a 70 second timeout on the socket. This will be adjusted in the future.

## 0.12.2
- Thanks to https://github.com/squidpickles handle new reconnect_url events, and rewrite event API to use match instead of if/else branches. Also change dev-dependencies to specific versions to comply with crates.io

## 0.12.1
- overhaul websocket teardown logic.

## 0.12.0
- Overhauled event parsing and added Event type, updated the EventHandler api, updated dependencies, added Error::Utf8 for utf8 decoding errors, rustfmt-ed the sources, various bugfixes.

### Compatibility Changes
- EventHandler's on_receive is now on_event with a different signature that takes the raw json string as well as the result of parsing the Event, for less library-user parsing and greater flexibility.
- RtmClient's get_outs method has been removed, and the type of the channel used for passing messages between the working threads has changed.


## 0.11.0
- Bugfix changes the color field of User to `Option<String>`, see: https://github.com/BenTheElder/slack-rs/issues/22

## 0.10.1
- Massive overhaul, implement support for almost all of the bots api, stronger error handling and lots of tests. Thanks a ton to https://github.com/mthjones, see https://github.com/BenTheElder/slack-rs/pull/17 for the main overhaul.

### Compatibility Changes
Methods that previously returned `Result<String,Error>` now return a typed `Result<Some_Slack_Response_Type, Error>`:

- `RtmClient::post_message` now returns `Result<api::chat::PostMessageResponse, Error>`
- `RtmClient::delete_message` now returns `Result<api::chat::DeleteResponse, Error>`
- `RtmClient::mark` now returns `Result<api::channels::MarkResponse, Error>`
- `RtmClient::set_topic` now returns `Result<api::channels::SetTopicResponse, Error>`
- `RtmClient::set_purpose` now returns `Result<api::channels::SetPurposeResponse, Error>`
- `RtmClient::add_reaction_timestamp` now returns `Result<api::reactions::AddResponse, Error>`
- `RtmClient::add_reaction_file` now returns `Result<api::reactions::AddResponse, Error>`
- `RtmClient::add_reaction_file_comment` now returns `Result<api::reactions::AddResponse, Error>`
- `RtmClient::update_message` now returns `Result<api::chat::UpdateResponse, Error>`
- `RtmClient::im_open` now returns `Result<api::im::OpenResponse, Error>`
- `RtmClient::channels_history` now returns `Result<api::channels::HistoryResponse, Error>`
- `RtmClient::im_close` now returns `Result<api::im::CloseResponse, Error>`
- `RtmClient::im_history` now returns `Result<api::im::HistoryResponse, Error>`
- `RtmClient::im_list` now returns `Result<api::im::ListResponse, Error>`
- `RtmClient::im_mark` now returns `Result<api::im::MarkResponse, Error>`

Forthcoming releases will see the implementation of the remaining files.upload and some convenient helpers such as a message builder can be expected in a later release, and the Error::Api will expose Slack api error types more strongly in a forthcoming release.
