0.4.0

New features

• Stateless widgets (#1284)
  A brand new widget API that removes the need to keep track of internal widget state. No more button::State in your application!

• Component trait (#1131)
  A new trait to implement custom widgets with internal mutable state while using composition and The Elm Architecture.

• Responsive widget (#1193)
  A widget that is aware of its dimensions and can be used to easily build responsive user interfaces.

• Experimental WebGL support (#1096)
  Applications can now be rendered into an HTML canvas when targeting Wasm by leveraging the WebGL support in wgpu. Thanks to @pacmancoder and @kaimast!

• Support for Raspberry Pis and older devices (#1160)
  The compatibility of our OpenGL renderer has been improved and should run on any hardware that supports OpenGL 2.1+ or OpenGL ES 2.0+. Additionally, we started maintaining Docker images for aarch64 and armv7 to easily cross-compile iced applications and target Raspberry Pis. Thanks to @derezzedex!

• Simpler Renderer APIs (#1110)
  The surface of the Renderer APIs of the library has been considerably reduced. Instead of a Renderer trait per widget, now there are only 3 traits that are reused by all the widgets.
