Callers of a method must supply all of the variables defined in the method declaration. Unlike some languages such as Kotlin and Python, Java doesn’t provide built-in support for optional parameter values. The Kotlin Blog provides a complete overview of this release and any issues encountered during testing may be reported on YouTrack.By: Eugen | Introduction to optional parameters in Java This solution will become the default option in a future release and may be tested by following the migration instructions.

The new memory manager makes the developer experience when creating cross-platform applications, such as for Android and iOS, easier by removing the differences between the JVM and Native platforms. The new Kotlin/Native Memory manager is now available as an Alpha release and brings improved performance and developer experience.

This latest release reintroduces the min(), max(), minBy(), maxBy(), minWidth() and maxWith() functions, which now return the collection element or throw an exception: fun main() ')) Comparable functions such as minBy(), maxBy(), minWidth() and maxWidth() were also renamed to include OrNull() at the end of the function name. Since the release of Kotlin 1.4, the min() and max() collections functions were renamed to minOrNull() and maxOrNull() since they return null when the collection is empty. To use these new features in version 1.7.0-Beta, configure the build scripts from the Early Access Preview. Starting with version 1.7.0, 'Milestone' releases are now called 'Beta' releases to align with the standard software release life cycle terminology, where 'Beta' means that no new features are added and the focus is on stabilizing the features with the help of feedback from the community. Regular expressions now support named capturing groups in Kotlin/JS and Kotlin/Native and allow checking for exact matches at specific positions. JetBrains has released Kotlin 1.7.0-Beta, enabling builder inference and definitely non-nullable types by default and reintroducing the min(), max(), minBy(), maxBy(), minWidth() and maxWith() functions.
