  • Rendering performance has been improved by ~20%. [@jstarry, #1296, #1309]

  • html!: Elements can be specified with dynamic tag names. [@siku2, #1266]

    In order to specify a dynamic tag name, wrap an expression with @{..}:

    let tag_name = "input";
    html! { <@{tag_name} value="Hello" /> }

  • HTML button element type can now be specified ("submit", "reset", or "button"). [@captain-yossarian, #1033]

  • html!: List rendering behavior is consistent no matter which syntax is chosen. [@siku2, #1275]

    html! { for node_list } is now equivalent to html! { node_list } when node_list is a Vec<VNode>.

  • KeyboardService events can now have default behavior prevented. [@ghpu, #1286]

  • Yew will check the current DOM input value before comparing with the desired value. [@ShadoySV, #1268]

  • html!: Void elements (<br/>, <input />) are no longer allowed to have children. [@kaoet, #1217]

  • Local agents no longer require Input and Output to implement Serializable. [@mkawalec, #1195]

• 🚨 Breaking changes

  • Renders are now done lazily and will not be executed until all updates have been processed. [@jstarry, #1309]

  • ConsoleService, DialogService, IntervalService, RenderService, TimeoutService, and WebSocketService methods are now static. [@teymour-aldridge, #1313]

  • html!: Children no longer implements Renderable. [@siku2, #1275]

    Replace instances of self.props.children.render() with self.props.children.clone().

  • Yew no longer stops propagation of events by default. [@jstarry, #1256]

    Event propagation is usually stopped when you have event listeners attached to nested elements and do not want the event to bubble up from where it was first captured. If your app has this behavior, you can stop propagation by calling stop_propagation() on the desired event.

  • The onsubmit listener now uses FocusEvent instead Event when using web-sys. [@siku2, #1244]

  • The onmousewheel and ontouchenter listeners have been removed. [@siku2, #1244]

  • The ondoubleclick listener is now named ondblclick. [@siku2, #1244]

  • FetchService methods are now static. [@teymour-aldridge, #1235]

    Instead of FetchService::new().fetch(..) you should now use FetchService::fetch(..)

  • The send_message_batch method has been removed from AgentLink. [@totorigolo, #1215]

  • Minimum supported rust version has been bumped from 1.40.0 to 1.42.0. [@mkawalec, #1195]

  • Every agent Reach type is now generic. [@mkawalec, #1195]

    In order to fix your app, simply append <Self> to the reach:

    Reach = Context -> Reach = Context<Self>

  • Removed Global agent because it was never implemented. [@jstarry, #1202]

  • Reduced visibility of internal agent types that were not intended to be public. [@jstarry, #1202]

v0.16.2

Changelog

• 🛠 Fixes

  • Fixed regression where messages sent from Component::create were skipped. [@jstarry, #1225]

v0.16.1

Changelog

• 🛠 Fixes

  • Worker script is now loaded from absolute path. [@domdir, #1175]

v0.16.0

Changelog

• ⚡️ Features

  • Added optional id, class, and placeholder properties to the Select component. [@Stigjb, #1187]

  • Re-export web-sys from Yew. This allows projects to use web-sys without adding it to their Cargo.toml. [@D4nte, #1176]

  • Added support for Option wrapped class names. [@liquidblock, #1085]

    The following code is now supported:

    let color: &Option<String> = &self.color;
    html! { <div class=("btn", color)></div> }

  • Added get_parent and get_component methods to ComponentLink to allow access to parent component state. [@jstarry, #1151]

• 🛠 Fixes

  • Fixed bug that caused html class attributes to be set to an empty string. [@liquidblock, #1085]
  • Fixed Private worker lifecycle event sending. [@joaquindk, #1146]

• 🚨 Breaking changes

  • Bumped minimum supported Rust version (MSRV) to 1.40.0. [@jstarry, #1152]

v0.15.0

Attention!

yew now uses web-sys by default. If your project uses web-sys, you can now drop the "web_sys" feature from your yew dependency.
Don't worry stdweb users, we have created a new alias crate for y'all called yew-stdweb. In order to use it, update your Cargo.toml yew dependency to the following:

yew = { version = "0.15", package = "yew-stdweb" }
