"Elements of Kotlin" Version 0.3 Released

Subscribers now have access to Version 0.3 of Elements of Kotlin, in PDF, EPUB, and MOBI/Kindle formats. Just log into your Warescription page to download it, or set up an account and subscribe!


In this update, there is one new “main” chapter, covering significant changes in Kotlin 1.3 and 1.4.

There is also a new “Kotlin, WTF?” short chapter, covering inline classes.

And, as usual, there were several bug fixes.


I hope to publish Version 0.9 and 1.0 in the next several months. After that, though, the timing of updates mostly will be dictated by the timing of Kotlin releases. That means 1-2 years between updates, depending on JetBrains’ plans.

That being said, leaving this book at 0.2 for 14 months was… not good. 😧 I apologize for that and hope to do better overall.
