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" }
