Changelog

0.6 - unreleased

Added start_app method. It's a shortcut to initialize a component and mount it to the body.
Added handling of files of input element. There is new ChangeData::Files variant of onchange handler.
Added ReaderService to read data from File instances. It supports two methods: read_file to read an entire file at a time and read_file_by_chunks to read a file by small pieces of data.
New example file_upload that prints sizes of uploaded files.

It was impossible to set value attribute for any tag instead of option, because it used inner value of VTag to keep the value for input element. Now value attribute works for options, progress tags, etc.

Context requirement removed. Not necessary to use Component<CTX> type parameter. Instead of a context a link to an environment provided with Component::create call. All examples had changed.
html! macro adds move modifier and the type of event for every handler (#240). Use <input oninput=|e| Msg::UpdateEvent(e.value), /> instead of obsolete <input oninput=move |e: InputData| Msg::UpdateEvent(e.value), />.
send_back method requires a mutable reference to self. This was added to prevent creating callbacks in view implementations.

Added Agents concept. Agents are separate activities which you could run in the same thread or in a separate thread. There is Context kind of agent that spawn context entities as many as you want and you have to interact with a context by a messages. To join an agent use Worker::bridge method and pass a link of component's environment to it.
Added three types of agents: Context - spawns once per thread, Job - spawns for every bridge, Public - spawns an agent in a separate thread (it uses Web Workers API under the hood).
Added <Component: with props /> rule to set a whole struct as a properties of a component.
All services are reexported within the yew::services module.
html! macro supports multiple classes in a single string. For example: <a class="button is-primary",>{ "Send" }</a>.
Added FetchOptions to set Credentials of fetch request.
FetchService aborts requests using AbortController.
Added SubmitEvent with onsubmit rule.
Added send_self method to ComponentLink to send messages itself immediately.

Bug with emscripten target RuntimeError: index out of bounds (#220) fixed with a new scheduler.
