 ## [Unreleased]
-### Added
-- `iced_core`, `iced_native`, and `iced_web` subcrates. [#17]
-- The `Length` type. It unifies methods like `width`, `fill_width`, etc. [#17]
 
+## [0.1.0-beta] - 2019-11-25
 ### Changed
-- `iced` becomes `iced_native`. The current `iced` crate will be empty until we have a first prototype of a low-level renderer. [#17]
-- Widgets expose their fields publicly, simplifying the `Renderer` traits in `iced_native`. [#17]
-- Widgets no longer hold a default `Style`. Related to [#6] and [#12]. [#17]
-- All `Renderer` traits now have total control to produce a `Node`. Related to [#6] and [#12]. [#17]
-- The tour example lives in its own crate now and it can be run both on native and web. [#17]
-
-### Removed
-- `Color` generic parameter in widgets. The new `Color` type is used now. This keeps widgets as reusable as possible. It may complicate implementing some runtimes, but a color mapper should be easily implementable in situations where colors are limited. [#17]

+- The old `iced` becomes `iced_native`. The current `iced` crate turns into a batteries-included, cross-platform GUI library.
