Bug fixes:

• Fixes #5203: Fixes regression in Dagger 2.60 where the Hilt compiler options (like fastInit) failed to propagate to the Hilt aggregation compilation tasks. (e181a0d)
• Fixes #5204: Fixes @CanIgnoreReturnValue import error by removing the annotation from ActivityRetainedComponentBuilder (3f2dd8f)

New features:

• Fixes #5165: Support nullable type annotations when using the flag -Adagger.nullableTypeAnnotations=enabled.
  For more details see https://dagger.dev/dev-guide/compiler-options#nullable-type-annotations. (4bedb4b)
• Fixes #5087: When using the Hilt Gradle plugin, you
  can now disable fastInit mode from the command line,
  e.g. -Pdagger.hilt.fastInit=false. For more details see https://dagger.dev/hilt/flags#fast-init. (0f7642b)
• Introduced parameterless @Binds methods to explicitly bind @Inject constructors. For more details see https://dagger.dev/dev-guide/#parameterless-binds. (4c81e94)

Potential breaking changes:

• When using the Hilt Gradle plugin, an error is now reported if a user sets a plugin-controlled flag (previously the plugin just ignored the user’s input). (a119ba6)
• Multidex support is removed. minSDK for Hilt is now 23, matching AndroidX
  (https://issuetracker.google.com/380448311) (1990bd1)

Bug fixes:

• Fixes #1290: Enabled Guava BetaApi checks (5b8b2bd)
• Fixes #5190, #5180, #5177: Updated Kotlin version ton 2.3.21 (7daaec5)
• Fixes #5160: Deferred ViewModelMetadata processing on error types or missing @AssistedFactory (59827c6)
• Fixes missing originating element attachments in a few Hilt processors to ensure correct incremental compilation tracking. (2930ca8)
• Fixes Dagger multibinding duplicate masking across Map components (compile-time validation)
  Adds strict compile-time detection for duplicate map multibinding keys across component boundaries. This is enabled via the -Adagger.mapMultibindingDuplicateDetectionFix=ENABLED. This option is DISABLED by default to maintain backward compatibility. See Compiler Options for more details. (504397e)

Bug fixes:

• Fixed #5116,#5099: Replaced Hilt's "android-classes" transform with attribute rules (f7e31b8)
• Fixed #5122: Fixed issue with slow incremental builds introduced by HiltSyncTask in AGP 9 support (1be5765)

Bug fixes:

• Fixed #5099: Fixes compilation error with jetifierEnabled=true in AGP 9 (8dcce87)
• Fixed #5098: Updated minimum required AGP version to 9.0.0 to make it clearer this is a requirement when using the Hilt Gradle plugin. (141e594)

Breaking changes:

(If you do not use Hilt or the Hilt Gradle plugin, this change does not affect you.)

This release adds AGP 9 support for the Hilt Gradle plugin. This means that if you use the Hilt Gradle Plugin, AGP 9 is now a requirement along with AGP 9’s own requirements like Gradle 9.1+ (https://developer.android.com/build/releases/agp-9-0-0-release-notes).

Note: AGP 9 also seems to cause issues with enableJetifier=true (see #5099). This will be fixed in a follow-up release.

Bug fixes/features:

• Fixed #4944, #4979: Support AGP 9 in HiltGradlePlugin (6afd7ea)

Note: AGP 9 support was held back from this release (0a5b42c) because it forces users onto AGP 9. It will be available in the next Dagger release (e92e3f3).

Potential breaking changes:

• Flipped default for dagger.useBindingGraphFix to enabled (d41e836).
  See https://dagger.dev/dev-guide/compiler-options#useBindingGraphFix.
  Fix: If this change breaks you it’s likely due to providing a binding in an incorrect module, (e.g. the binding requests an Activity but is installed in the SingletonComponent). The fix is to move the @Provides so that it is installed into the correct component (e.g. the ActivityComponent instead of SingletonComponent). You can also set dagger.useBindingGraphFix=disabled but note that this flag is only temporary and will eventually be removed.
• The use of abstract var in components is now banned in super types.
  The reason for this change is that an abstract var property creates both a getter and a setter on the component which is almost always unintentional.
  Fix: If this change breaks you, use either an abstract val foo: Foo if you need a getter or abstract fun inject(foo: Foo) if you need an inject method. Note that abstract var is already banned if it is declared directly on the @Component class/interface, but this change fixes the check so that it’s banned even if it’s inherited from a super type.

Bug fixes/features:

• Fixes #1116, #1630, Supported Map<K, Lazy<V>> as a multibinding request type. (7f981a4)
• Fixes #3601. No longer adds a deprecation warning for unused dependencies on setters on the component builder. (1cf9dfc)
• Fixes #4982:
  • Added validation to prevent using Java keywords in Dagger-generated code (72e21a8)
  • Added error for binding elements names that are Java keywords. (38071c5)
  • Java keyword validation is now performed earlier during the superficial validation stage. (7f6f7bd)

Bug fixes

• Fixed #4847: Fixed an issue with the Hilt Gradle Plugin registered transforms on projects using Gradle 9.0.0 (ea570e7)
• Fixes #4898: Fixed an issue with backwards compatibility handling for libraries that export Hilt roots. (85c470c)
• Fixes #4937: Fixed the incorrectly declared version of the Kotlin stdlib dependency in the Hilt Gradle Plugin. (deefd9a)
• Updated ASM dependency to 9.8 (365bc49)

Bug fixes

• Fixes #4734: Updated Hilt's Gradle Plugin detection of AGP to maximize compatibility and avoid the confusing 'The Hilt Android Gradle plugin can only be applied to an Android project.' error when the plugin is on an Android project. (20adecb)
• Fixes #4848: Set coreLibrariesVersion for the Kotlin compilation of the Hilt Gradle Plugin to further improve backwards compatibility. (00c7fc2)
• Fixes #4848: Use api / language versions for the Kotlin compilation of the Hilt Gradle Plugin to not force projects to update to Kotlin 2.2.0, the current version used by the plugin. (58e4992)
• Fixes #4780: Add support for the Jakarta Singleton annotation in Hilt. (ec7f76f)
• Fixes #4917: Removes the explicit dependency to androidx.annotation:annotation-jvm and to a beta version of it. (092a85a)
• Limit number of similar bindings shown in error messages to 20 (59ac2f9)
• Update wording for @AssistedInject error to be more specific. (1702e79)

Potential breaking changes

The generated Factory/MembersInjector constructors have changed from public to private. This shouldn’t affect most users since these classes are only meant to be called by Dagger’s other generated code. If you do happen to be broken by this change, you should avoid calling Dagger’s generated Factory/MembersInjector classes directly. For a temporary solution, you can also switch to using the public static methods to create an instance. (165cf20)

Bug fixes

Fixes #4779. Unshades the Kotlinx Metadata to support Kotlin 2.2.0 (bfa88b9)

Bug fixes

• [Dagger] Fixes #4676: Fixes IndexOutOfBoundException when returning suspend from @Provides method. (5d59aed)
• [Dagger] Fixes #4658: Fixes NoSuchMethodError due to incorrect Guava runtime (Dagger’s Guava version is now temporarily pinned to 33.0.0 to avoid the issue). (9fc3df4)
