Kotlin 1.4.20

CHANGELOG

Android

• KT-42121 Deprecate Kotlin Android Extensions compiler plugin
• KT-42267 Platform declaration clash error in IDE when using kotlinx.android.parcel.Parcelize
• KT-42406 Long or infinite code analysis on simple files modification

Backend. Native

• KT-27534 Bridges to Nothing-returning methods have incorrect signature
• KT-30284 Native: Nothing? type for expression override and crash
• KT-36430 Optimize when with in range cases
• KT-38787 Missing optimization for "in range" check
• KT-39100 Make Native behaviour of property initialization consistent with JVM
• KT-39798 Override equals/hashCode in functional interface wrappers on Native
• KT-39800 equals/hashCode on adapted function references on Native
• KT-41394 Compilation failed: Backend Internal error: Exception during IR lowering
• KT-41907 Framework test segfaults on GC on watchos_x86 compiled with -opt

Compiler

New Features

• KT-21147 JEP 280: Indify String Concatenation (StringConcatFactory)
• KT-34178 Scripts should be able to access imports objects
• KT-35549 Support kotlin-android-extensions in JVM IR backend (for use with Jetpack Compose projects)
• KT-31567 Support special semantics for underscore-named catch block parameters

Performance Improvements

• KT-20571 Coroutines: Reduce number of local variables stored at suspension point
• KT-28016 Coroutine state-machines spill/unspill shall be optimized using data-flow analysis
• KT-33394 UI freezes triggered by QualifiedExpressionResolver.resolveToPackageOrClassPrefix
• KT-36814 Support optimized delegated properties in JVM_IR
• KT-36829 Optimize 'in' expressions (operator fun contains) in JVM_IR
• KT-41741 NI: "AssertionError: Empty intersection for types" with generic Java collection
• KT-42195 NI: prohibitively long compilation time for values of nested data structures with type inference
• KT-42221 Native compiler never finishes frontend phase after migrating to Kotlin 1.4.10

Fixes

• KT-11713 Refine visibility check for synthetic property with protected setter
• KT-16222 Coroutine should be clearing any internal state as soon as possible to avoid memory leaks
• KT-25519 Extra inline marks inside suspending function callable reference bytecode
• KT-33226 Object INSTANCE field not annotated with NotNull in generated bytecode
• KT-35495 FIR: forbid non-Java synthetic properties
• KT-35651 Kotlin stdlib has greater resolution priority than jars added via @file:DependsOn annotation
• KT-35716 Using @JvmOverloads in @JvmStatic functions in interface companion objects causes a ClassFormatError
