This means that instead of redeclaring the annotated class in the key, for example `@ViewModelKey`, you can now omit it and it will be inferred. ```kotlin @​ViewModelKey // <-- implicitly HomeViewModel::class @​ContributesIntoMap(AppScope::class) class HomeViewModel : ViewModel() ``` For classes, the implicit type is the annotated class. For `@Binds` declarations, the receiver or single parameter are the implicit type. You may still specify an explicit type. The compiler will warn you if you specify a redundant one. If you need to suppress this diagnostic temporarily to ease migration, you can add `-Xwarning-level=MAP_KEY_REDUNDANT_IMPLICIT_CLASS_KEY:disabled` to your compiler arguments. The compiler will also error if you attempt to do this on `@Provides` declarations, as those cannot be inferred. Metro's first-party class-based map keys (like `@ClassKey`, `@ViewModelKey`, etc.) now support this. Custom map keys can opt-in to this by setting `MapKey.implicitClassKey` to true. See its doc for more details. ```kotlin @​MapKey(implicitClassKey = true) annotation class ViewModelKey(val value: KClass<out ViewModel> = Nothing::class) ``` ##### Misc - **\[metrox-viewmodel]** Add `mingwX64` target. ##### Enhancements - **\[FIR]** Add diagnostic to ensure map key annotations support `FUNCTION` targets if they have a `@Target` annotation. - **\[FIR]** Improve annotation argument matching to only use fully resolved names or none at all. This helps avoid situations in the past with interop where an argument at the same index and type but different name could incorrectly be used. ##### Fixes - **\[IR]** Fix `IllegalArgumentException` thrown when there are multiple top-level functions with the same name but only one is annotated with `@Inject`. - **\[IR]** Only store a given binding container's own provider factories in metro metadata. This resolves a bug where we could end up duplicate-processing upstream providers in dynamic factories. - **\[IR]** Fix a severity conversion compat function call for Kotlin 2.3.20+. - **\[IR]** Ensure stable sort of output `SuspiciousUnusedMultibinding` locations. - **\[IR]** Don't skip dynamic keys inherited from parent graphs when working with dynamic graphs. - **\[IR]** Propagate `@OptionalBinding` annotations to generated static factory creators if present. - **\[IR]** Preserve nullability when remapping parameters with generic layers. - **\[Runtime]** `IntoSet` and `IntoMap` no longer have a `Target` of `AnnotationTarget.CLASS` ##### Changes - The Metro compiler now requires JVM 21+. Note that the runtime JVM artifacts still target 11 unless otherwise documented. - The Metro Gradle plugin now requires JVM 21+. - The Metro Gradle plugin now requires Gradle 9+. Note that if you do not use Kotlin Gradle DSL, it may work on older versions but YMMV. - The Metro Gradle plugin now targets Kotlin `2.2`. - `@Assisted.value` is formally deprecated now. See the [docs](https://zacsweers.github.io/metro/latest/injection-types/#assisted-injection) on why in case you missed this! TL;DR, Metro matches by parameter names going forward. - Metro's main branch now builds with Kotlin `2.3.20` but still targets Kotlin 2.2 for its runtime artifacts and supports 2.2.20 all to 2.4.0 dev builds in its compiler. - Remove deprecated `macosX64`, `tvosX64`, and `watchosX64` targets. - Update Kotlin 2.4 compat support from `2.4.0-dev-539` to `2.4.0-dev-2124`. This should support the upcoming IntelliJ 2026.1 release as well as the upcoming Kotlin `2.4.0-Beta1`. - Test IntelliJ `2026.1 RC`. - Update shaded Wire dependency to `6.1.0`. ##### Contributors Special thanks to the following contributors for contributing to this release! - [@​Asapha](https://redirect.github.com/Asapha) - [@​ChristianKatzmann](https://redirect.github.com/ChristianKatzmann) - [@​grandstaish](https://redirect.github.com/grandstaish) - [@​jonamireh](https://redirect.github.com/jonamireh) - [@​kevinguitar](https://redirect.github.com/kevinguitar) - [@​svenjacobs](https://redirect.github.com/svenjacobs) - [@​vRallev](https://redirect.github.com/vRallev) </details> --- ### Configuration 📅 **Schedule**: Branch creation - At any time (no schedule defined), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Enabled. ♻ **Rebasing**: Whenever PR is behind base branch, or you tick the rebase/retry checkbox. 🔕 **Ignore**: Close this PR and you won't be reminded about these updates again. --- - [ ] <!-- rebase-check -->If you want to rebase/retry this PR, check this box --- This PR was generated by [Mend Renovate](https://mend.io/renovate/).
