## [0.3.0] - 2019-09-05
### Added
* Add support for decoding the optional `Content-Type` field in messages.
* Implement support for the following client-to-server messages:
* `workspace/didChangeWorkspaceFolders`
* `workspace/didChangeConfiguration`
* `workspace/didChangeWatchedFiles`
* `workspace/symbol`
* `workspace/executeCommand`
* Implement support for the following server-to-client messages:
* `telemetry/event`
* `client/registerCapability`
* `client/unregisterCapability`
* `workspace/applyEdit`
### Changed
* Bump minimum Rust version to 1.34.0.
* Rename `highlight()` to `document_highlight()` to better match the
specification.
* Make all notification methods into provided methods (PR #34).
* Change `LspService` request type from `String` to `Incoming` (PR #28).

## [0.2.0] - 2019-09-03
### Added
* Add `ExitedError` for when calling `LspService` after it has already exited.
### Changed
* Language server now returns server error code `-32002` if any method is called
before `initialize` request is received, [as per the spec][init].
* `LspService` sets `Service::Error` to `ExitedError`.
* `Server` can now accept any service where `Service::Error` is convertible to
`Box<dyn Error + Send + Sync>`. This enables compatibility with most Tower
middleware.
* Retain error or success from future in `ExitReceiver::run_until_exit()`.
* Remove `'static` bounds on some `Server` and `ExitReceiver` methods.
