Kotlin 1.4 release was made available to the developer community a couple of weeks ago with a strong focus on improving quality-of-life and performance as well as new features.
This release comes with improved IDE performance and stability, including freezes or memory leaks, all these making Kotlin 1.4 up to four times faster.

As for language features this release now has SAM (Single Abstract Method) conversions for Kotlin In computing, an interface is a shared means by which two or more separate components of a computer system exchange information. The interface could be between the human and a computing device, two computers, computer hardware, software or peripheral devices. Examples include touch screens which allow information to be exchanged between a human and the devices, A software graphical interface,... More, explicit API mode for library authors that allows the compiler to perform additional checks that help make the library’s API clearer and more consistent.
Mixing named and positional arguments where you can now specify a name for an argument in the middle of a set of positional arguments. Moreover, you can mix positional and named arguments any way you like, as long as they remain in the correct order.
Trailing commas are now supported in enumerations such as argument and parameter lists.
Callable reference improvements in references to functions with default argument values and function references in Unit-returning functions. References that adapt based on the number of arguments in a function, suspend conversion on callable references, and while using break and continue inside when in loops.
