Kotlin 1.0.3 tackles bug fixes, tooling improvements and performance boosts

What’s new in the compiler, you ask? There have been a few improvements to diagnostic messages and there’s now a more efficient bytecode (no more iterator in indices loop, avoid unnecessary operations with Unit). Plus, there’s a new option -jdk-home to specify the JDK against which the code is compiled and there are a few options to specify Kotlin language version (-language-version) and target Java version (-jvm-target) (will have effect in 1.1, added now for forward compatibility).

Kotlin 1.0.3: Changes in the IDE

Kotlin 1.0.3 comes with autosuggestion for Java to Kotlin conversion for Java code copied from browser and other sources outside of the IDE and there’s a language injection for strings passed to parameters annotated with @Language. Also predefined Java injections applied in Kotlin code. Unlike before, completion always shows non-imported classes and methods; it also adds imports automatically when they are selected.

Here is the entire list of changes.
