CHANGELOG

1.1.3-3

• KT-18954 Fixed exception in Kotlin plugin updater

1.1.3-2

Fixes

• 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-18689 Incorrect bytecode generated when passing a bound member reference to an inline function with default argument values
• KT-18377 Syntax error while generating kapt stubs
• KT-18411 Slow debugger step-in into inlined function
• KT-18687 Deadlock in resolve with Kotlin 1.1.3
• KT-18726 Frequent UI hangs in 2017.2 EAPs
