v4.2.2: Koin 4.2.2

Compare Source

Maintenance release for the 4.2.x line — resolver regression fixes from the 4.2.0 CoreResolverV2 rewrite, ViewModel/scope fixes, a Ktor request-scope fix, plus new tvOS support and an R8/ProGuard guide.

Anyone hitting resolver issues on 4.2.0/4.2.1 should upgrade to 4.2.2.

Bug Fixes

• Stacked params no longer shadow qualified dependencies (#​2370, #​2408) — A value passed via parametersOf could be returned for a get(named(...)) request of the same type, shadowing the qualified definition. Qualified lookups are now registry-only and never read the parameter stack — parameters carry no qualifier, so they can't satisfy a qualified request.

• Root factory no longer resolves its scoped dependencies from _root_ (#​2379) — When a non-single factory defined in the root scope was resolved from a child scope, CoreResolverV2 resolved its scoped dependencies against _root_ instead of the requesting scope. Linked-scope resolution now runs the factory against the requesting scope (single instances keep their root-bound semantics, preserving #​2325).

• viewModelScopeFactory scope is linked to its parent (#​2299) — A ViewModel scope created via viewModelScopeFactory() was not linked to the originating scope, so dependencies declared in the parent couldn't be resolved. The created scope is now linked to its parent (except when the parent is root).

• Tolerate non-String environment properties (#​2348) — Loading environment/system properties whose values aren't String threw ClassCastException due to an unchecked map cast. Non-String values are now preserved as Any and only String keys are required.

• Unique Ktor request-scope ids under concurrency (#​2410) — Concurrent requests could collide on request-scope ids. Ids are now generated from a monotonic counter seeded once at startup. Thanks @​lfavreli-betclic!

• Actionable errors for SavedStateHandle / viewModelScope { } (#​2044, #​2417) — Resolving SavedStateHandle without the proper extras, or using viewModelScope { } without the viewModelScopeFactory() option, now produces a clear, actionable error message instead of an opaque failure.

Added

• tvOS targets for koin-core-viewmodel (#​2426) — koin-core-viewmodel now publishes tvosArm64, tvosX64, and tvosSimulatorArm64, unblocking ViewModel usage on tvOS.

• Consumer R8/ProGuard rules + guide — Android and ViewModel artifacts now ship consumer R8/ProGuard rules in their AARs, and a new R8 / ProGuard guide documents keep rules for minified builds.

Improvements

• O(1) secondary-type registration in bind() / binds() — bind/binds now append secondary types in O(1) instead of reallocating the type list per binding, removing quadratic cost when a definition declares many bindings. No user-visible behavior change.

Documentation

• Navigation 3 typed entryProvider (#​2336) — Added guidance on using Koin with the typed entryProvider in the Navigation 3 reference.

v4.2.1: Koin 4.2.1

Support for Compile Safety with Koin Compiler 1.0.0-RC1

• Koin Compiler Plugin 1.0.0-RC1 - https://github.com/InsertKoinIO/koin-compiler-plugin/releases/tag/1.0.0-RC1

Bug Fixes

• Fix stacked-params lookup on linked scopes (#​2387) — The 4.2.0 resolver rewrite (CoreResolverV2) walked linked scopes but dropped the per-parent stacked-parameters check that 4.1.x performed via recursion. This broke patterns where AndroidParametersHolder is stacked on the factory scope by KoinViewModelFactory and SavedStateHandle is then resolved from a child ViewModel scope. Linked-scope resolution now also checks stacked params on each parent scope.

• Restore ABI compatibility for runOnKoinStarted (#​2391) — The 4.2.0 release inadvertently broke binary compatibility for runOnKoinStarted on JVM. Fixed by restoring the original JVM class name via @JvmName/@JvmMultifileClass annotations.

• Fix scope _closed concurrency issue (#​2389) — The Scope._closed flag was not volatile, which could cause stale reads under concurrent access.

Improvements

• Improved Scope resolution error messages — CoreResolverV2 now provides clearer error messages when scope resolution fails, making it easier to diagnose misconfigured scopes.

• Added apiCheck to CI — Binary compatibility validation (kotlinx.binary-compatibility-validator) now runs on every PR to prevent future ABI breaks.

Documentation

• parametersOf type-collision warning (#​2328) — Added a caution note explaining that when a value passed via parametersOf has the same type as the requested definition, Koin returns the value directly and skips the factory block. Suggests using a wrapper type as a workaround.
