New Dagger Features

Added a @LazyClassKey annotation that supports using class names as a map key. Unlike the existing @ClassKey, the map generated by @LazyClassKey won’t eagerly load all of the classes for the keys. This can be useful in situations or environments where classloading can be expensive, such as on Android. For more information, see https://dagger.dev/dev-guide/multibindings

Potential breaking changes

Protected fields using @Inject are now banned in Kotlin classes. This is because Kotlin protected fields are not accessible by code in the same package, unlike Java. This has been working up to this point because Dagger generates Java code, but that is unintentional and would break if Dagger switched to generate Kotlin code.(408431a)

Fixed #3197: Used the new @LazyClassKey Dagger feature to remove the keep rule for @HiltViewModel class names. This allows obfuscation of @HiltViewModel annotated ViewModel class names with R8. (0786d0a)
Added @SkipTestInjection which can be used for skipping test injection in Hilt Android tests, which may be useful if building separate custom test infrastructure to inject the test class from another Hilt component. (c40811e)

Improve Dagger MissingBinding error messages to give more information and be more consistent. (c872238)
Fixed #4201: Suppress warning for casting in Dagger generated code. (813ffce)
Fixed #4203: Removes @Deprecated annotation causing warnings (3cbc94a)
Fixed #4199: Support member injections from type aliased superclass (662d823)
Complete Ksp support for Dagger Android: Added a Ksp Processor for Dagger Android ProguardProcessor that was previously missed. The ProguardProcessor is a Dagger Android implementation detail that makes sure the AndroidInjector works correctly when shrinking tools obfuscate @ContributesAndroidInjector annotated injector class names.
