0.2.0

• New: Nullable bindings are now allowed! See the nullability docs for more info.
• Enhancement: Add diagnostics for multibindings with star projections.
• Enhancement: Add diagnostic for map multibindings with nullable keys.
• Fix: Ensure assisted factories' target bindings' parameters are processed in MetroGraph creation. Previously, these weren't processed and could result in scoped bindings not being cached.
• Fix: Fix duplicate field accessors generated for graph supertypes.
• Add compose navigation sample.

Special thanks to @bnorm and @yschimke for contributing to this release!

0.1.3

• Change: Multibindings may not be empty by default. To allow an empty multibinding, @Multibinds(allowEmpty = true) must be explicitly declared now.
• New: Write graph metadata to reports (if enabled).
• New: Support configuring debug and reports globally via metro.debug and metro.reportsDestination Gradle properties (respectively).
• Enhancement: Change how aggregation hints are generated to improve incremental compilation. Externally contributed hints are now looked up lazily per-scope instead of all at once.
• Enhancement: Optimize empty map multibindings to reuse a singleton instance.
• Enhancement: Report error diagnostic if Dagger's @Reusable is used on a provider or injected class.
• Enhancement: Tweak diagnostic error strings for members so that IDE terminals auto-link them better. i.e., instead of printing example.AppGraph.provideString, Metro will print example.AppGraph#provideString instead.
• Enhancement: Support repeatable @ContributesBinding annotations with different scopes.
• Fix: Fix incremental compilation when @Includes-annotated graph parameters change accessor signatures.
• Fix: Don't allow graph extensions to use the same scope as any extended ancestor graphs.
• Fix: Don't allow multiple ancestor graphs of graph extensions to use the same scope.
• Fix: Handle scenarios where the compose-compiler plugin runs before Metro's when generating wrapper classes for top-level @Composable functions.
• Fix: Fix an edge case in graph extensions where child graphs would miss a provided scoped binding in a parent graph that was also exposed as an accessor.
• Fix: Fix Dagger interop issue when calling Javax/Jakarta/Dagger providers from Metro factories.
• Fix: Fix Dagger interop issue when calling dagger.Lazy from Metro factories.
• Fix: Preserve the original Provider or Lazy type used in injected types when generating factory creators.
• Temporarily disable hint generation in WASM targets to avoid file count mismatches until KT-75865.
• Add an Android sample: https://github.com/ZacSweers/metro/tree/main/samples/android-app
• Add a multiplatform Circuit sample: https://github.com/ZacSweers/metro/tree/main/samples/circuit-app
• Add samples docs: https://zacsweers.github.io/metro/samples
• Add FAQ docs: https://zacsweers.github.io/metro/faq

• Change: Make providerOf use InstanceFactory under the hood.
