Upgrade Kotlin Version

[opticyclic]

The version of Kotlin (1.2.71) is almost 3 years old https://github.com/JetBrains/kotlin/releases/tag/v1.2.71
CordApps no longer compile in IDEA by default.
When building with IDEA you get the error:
Kotlin: Language version 1.2 is no longer supported; please, use version 1.3 or greater.

Hi!

What is the state of it?

The newest (and not only) JetBrains products doesn't support the old Kotlin plugins which makes code completion not working for Corda applications.

Yeh this is a real pain. Want to use the latest IntelliJ and held back by Corda. Any update on when Corda will upgrade from a super old deprecated version of Kotlin? In fact you really need to upgrade to 1.6 or 1.7 for it to work well with the latest IntelliJ. For your code to be usable in the latest IntelliJ really isn't much to ask.
