 `taffy` is a flexible, high-performance, cross-platform UI layout library written in [Rust](https://www.rust-lang.org).
 
-Currently, we only support a [flexbox](https://css-tricks.com/snippets/css/a-guide-to-flexbox/) layout algorithm, but support for other paradigms [is planned](https://github.com/DioxusLabs/taffy/issues/28).
+Currently Taffy implements only CSS based layout algorithms:
+
+- The stable `0.2.x` releases of Taffy implements the [flexbox](https://css-tricks.com/snippets/css/a-guide-to-flexbox/) layout algorithm.
+- Support for [CSS Grid](https://css-tricks.com/snippets/css/complete-guide-grid/) is in preview. If you wish to try this out then you should use the `0.3.x` alpha releases and enable the `experimental_grid` cargo feature. For information, see the [release notes](https://github.com/DioxusLabs/taffy/blob/main/RELEASES.md) and the [tracking issue](https://github.com/DioxusLabs/taffy/issues/204). Experimentation with the CSS Grid implementation is encouraged, and feedback and bug reports are welcomed.

+Support for other paradigms [is planned](https://github.com/DioxusLabs/taffy/issues/28).
 
 This crate is a collaborative, cross-team project, and is designed to be used as a dependency for other UI and GUI libraries.
 Right now, it powers:

 # Release Notes
 
-## 0.3.0-alpha1 (Unreleased)
+## 0.3.0-alpha1
 
 This is the first in a series of planned alpha releases to allow users of Taffy to try out the new CSS Grid layout mode in advance of a stable release. We hope that by marking this is alpha release we are clearly communicating that this a pre-release and that the implementation is not yet of production quality. But we never-the-less encourage you to try it out. Feedback is welcome, and bug reports for the Grid implementation are being accepted as of this release.
