+# v0.9 is a transitional/preview release
+
+The RGB crate is getting a major update. We welcome your feedback about the crate!
+
+* Are the names of the traits and their methods good?
+* Are there any standard library traits you'd like implemented on the pixel types?
+* Is the split between `Pixel`, `HetPixel`, `HasAlpha` sensible? (pixels support a different type for the alpha channel, and there's `Rgbw` without alpha).
+* With the `legacy` feature enabled, is the crate sufficiently backwards compatible? (later we're going to use semver trick to provide interoperability with other v0.8 crates)
+* Without the `legacy` feature enabled, is the upgrade easy? Anything missing?
+
+[Please open issues in the repo with the feedback](https://github.com/kornelski/rust-rgb/issues) or message [@kornel@mastodon.social](https://mastodon.social/@kornel).
