+
+PubGrub 0.3 has a more flexible interface and speeds resolution significantly. The public API is very different now, we
+recommend starting the migration by implementing the new `DependencyProvider` interface following the
+[Guide](https://pubgrub-rs.github.io/pubgrub/pubgrub/).
+
+All public interfaces are now in the root of the crate.
+
+In the main interface, `DependencyProvider`, `choose_package_version` was split into two methods: `prioritize`
+for choosing which package to decide next by assigning a priority to each package, and `choose_version`. The generic
+parameters became associated types. The version set is configurable by an associated type.
+
+`Dependencies` gained a generic parameter for custom incompatibility type outside version conflicts, such as packages
+not available for the current platform or permission errors. This type is on `DependencyProvider` as
+`DependencyProvider::M`.
+
+`pubgrub::range::Range` now lives in its own crate as [`version_ranges::Ranges`](https://docs.rs/version-ranges/0.1/version_ranges/struct.Ranges.html). A `Version` can be almost any
+ordered type now, it only needs to support set operations through `VersionSet`. 
+
+At a glance, this is the new `DependencyProvider` interface:
+
+```rust
+pub trait DependencyProvider {
+    type P: Package;
+    type V: Debug + Display + Clone + Ord;
+    type VS: VersionSet<V = Self::V>;
+    type M: Eq + Clone + Debug + Display;
+    type Priority: Ord + Clone;
+    type Err: Error + 'static;
+
+    fn prioritize(
+        &self,
+        package: &Self::P,
+        range: &Self::VS,
+        package_conflicts_counts: &PackageResolutionStatistics,
+    ) -> Self::Priority;
+
+    fn choose_version(
+        &self,
+        package: &Self::P,
+        range: &Self::VS,
+    ) -> Result<Option<Self::V>, Self::Err>;
+
+    fn get_dependencies(
+        &self,
+        package: &Self::P,
+        version: &Self::V,
+    ) -> Result<Dependencies<Self::P, Self::VS, Self::M>, Self::Err>;
+
+}
+```
