v4.2.1: Koin 4.2.1

Compare Source

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.

Kotlin 2.3.20

New Features

• Ktor 3.4 DI Bridge — Full integration with Ktor's new DI system (ktor-server-di), bridging Ktor ↔ Koin dependency injection both ways
• Dagger Bridge (koin-dagger-bridge) — New module to help inject Koin components from Dagger side
• AndroidX Navigation 3 support — Entry point provider with metadata parameter passing (animations, etc.), generic EntryProvider, and navigation scopes
• Navigation Scope for Compose Nav 2 — Added scoped navigation support for Compose Navigation 2
• Lazy Modules — Parallel loading at startup for improved performance, with benchmarks
• strictOverride option — New definition option to override explicitly
• koinActivityInject — Helper to retrieve dependencies against Activity scope
• Koin Compiler Stubs — Added stubs for KoinApplication.modules() functions
• KoinApplication.withConfiguration() — New configuration support

Performance & Stability

• Core Resolver V2 — Fixed parameter stack propagation, injected params handling, and child scope/ViewModel scope resolution
• Scope Resolution & Thread Safety — Performance optimization with safer ScopeFactory protecting all operations from parallel calls
• ThreadLocal loading optimization — Avoid cost per Scope (#​2306)
• getAll no longer sorted by default — Instances come as declared; sort on purpose if needed
• Params stack access optimization

Bug Fixes

• Fix sharedKoinViewModel with type-safe navigation routes (#​2293)
• Fix qualified name usage in WASM (#​2312)
• Fix premature release of scope & context in Compose — don't drop in onForgotten (#​2274)
