1.1.60-eap-43

What's new

• Bug fixes and further improvements in support for JSR-305 nullability annotations:
  • Type qualifier defaults can now be used with ElementType.TYPE_USE to provide nullability information for types in all positions including type arguments, upper bounds of type parameters and wildcard types
  • Migration status of custom nullability annotations can be controlled with the @UnderMigration annotation (packaged in a new artifact kotlin-annotations-jvm)
  • Support for fine-grained migration status control on the library user side with the compiler configuration flag -Xjsr305
• Experimental support for Kotlin/JS incremental compilation in Gradle builds; it is disabled by default and can be enabled by setting kotlin.incremental.js = true in gradle.properties or local.properties
• Bug fixes in Parcelable implementation generation with @Parcelize
• Lots of bug fixes in the compiler and IDE
• New inspections, performance improvements and bugfixes in the IntelliJ plugin
• Other improvements in support for Gradle incremental builds

1.2-M2

Compiler

Breaking change: Java-default method calls

Kotlin interface members overriding Java-default methods while targeting JVM 1.6 now produce an error on super calls requiring to be compiled with -jvm-target 1.8 option

Standard library

Revised windowed/pairwise operations

• windowed function now has its step parameter defaulting to 1.
  It also gets an additional optional parameter partialWindows, which controls what to do with incomplete windows in the end. By default it is false, which means incomplete windows are dropped.
• pairwise function name was too confusing, it was unclear how it paired the elements together. Now it is called zipWithNext, so it is more clear that each element is zipped with the next element in a collection.

Common math operations in the standard library

There was a longstanding request to support math operations in the standard library KT-4900. Until now one had to resort to math functions and constants from java.lang.Math class in JVM platform and to kotlin.js.Math which exposed native JS Math functions to Kotlin code in JS platform.
But now we're introducing the following groups of API in the kotlin.math package:

• constants: PI and E;
• trigonometric: cos, sin, tan and inverse of them: acos, asin, atan, atan2;
• hyperbolic: cosh, sinh, tahn;
• exponentation: pow (an extension function), sqrt, hypot, exp, expm1;
• logarithms: log, log2, log10, ln, ln1p;
• rounding:
  - ceil, floor, truncate, round (half to even) functions;
  - roundToInt, roundToLong (half to integer) extension functions;
• sign and absolute value:
  - abs and sign functions;
  - absoluteValue and sign extension properties;
  - withSign extension function;
• max and min of two values;
• binary representation:
  - ulp extension property;
  - nextUp, nextDown, nextTowards extension functions;
  - toBits, toRawBits, Double.fromBits (these are in the kotlin package).

Previous releases

This release also includes fixes and improvements from 1.2-M1 and 1.1.4-eap-54 releases

1.1.3-2

• Noarg compiler plugin reverted to 1.1.2 behavior: by default, it will not run any initialization code
  from the generated default constructor. If you want to run initializers, you need to enable
  the corresponding option as described in the documentation.
  Note that if a @noarg class has initializers that depend on constructor parameters, you will get incorrect
  compiler behavior, so you shouldn't enable this option if you have such classes in your project.
  This resolves KT-18667 and KT-18668.

• KT-18687 Deadlock in resolve with Kotlin 1.1.3
