 ## [Unreleased]
 ### Added
-- `"system_font"` feature gates reading system fonts. [#370]
+- Support for the [`smol`] async runtime. [#699]
+
+[#699]: https://github.com/hecrj/iced/pull/699
+[`smol`]: https://github.com/smol-rs/smol
+
+## [0.2.0] - 2020-11-26
+### Added
+- __[`Canvas` interactivity][canvas]__ (#325)  
+  A trait-based approach to react to mouse and keyboard interactions in [the `Canvas` widget][#193].
+
+- __[`iced_graphics` subcrate][opengl]__ (#354)  
+  A backend-agnostic graphics subcrate that can be leveraged to build new renderers.
+
+- __[OpenGL renderer][opengl]__ (#354)  
+  An OpenGL renderer powered by [`iced_graphics`], [`glow`], and [`glutin`]. It is an alternative to the default [`wgpu`] renderer.
+
+- __[Overlay support][pick_list]__ (#444)  
+  Basic support for superpositioning interactive widgets on top of other widgets.
+
+- __[Faster event loop][view]__ (#597)  
+  The event loop now takes advantage of the data dependencies in [The Elm Architecture] and leverages the borrow checker to keep the widget tree alive between iterations, avoiding unnecessary rebuilds.
+
+- __[Event capturing][event]__ (#614)  
+  The runtime now can tell whether a widget has handled an event or not, easing [integration with existing applications].
+
+- __[`PickList` widget][pick_list]__ (#444)  
+  A drop-down selector widget built on top of the new overlay support.
+
+- __[`QRCode` widget][qr_code]__ (#622)  
+  A widget that displays a QR code, powered by [the `qrcode` crate].
