Today we\u2019re releasing Kotlin 1.4.0! Over the past years, we\u2019ve been working hard on making Kotlin a programming language that is fun, enjoyable, and productive to work with. To continue our pursuit of this goal with this version of Kotlin, we put a lot of energy and effort into improving the performance and quality of Kotlin and its tooling. We are also excited to announce support for several new language features, including the long-awaited SAM conversions for Kotlin interfaces.<\/p>\n

To help you get the most out of the changes and improvements introduced in Kotlin 1.4, we\u2019re inviting all of you to the Kotlin 1.4 Online Event<\/a>, where you will be able to enjoy four days of Kotlin talks, Q&As with the Kotlin team, and more \u2013 completely free.<\/p>\n

We\u2019re delighted to see how popular Kotlin is becoming! The numbers of active users \u2013 we\u2019ll explain this metric in more detail in a future blog post \u2013 have been especially encouraging. Here, we are seeing a 1.5-fold increase over the previous year\u2019s figures.<\/p>\n

According to the StackOverflow Developer Survey 2020<\/a>, Kotlin has climbed to 13th place among the most popular programming languages for professional developers, and we\u2019re happy to see that Kotlin is one of the top 5 most loved languages.<\/p>\n

Many companies have picked Kotlin as their language of choice, and are successfully using it on all platforms. We’re happy to see this tendency, and we\u2019re tremendously grateful that so many of these companies have made case studies available for the community to read and learn from. Here are just a few amazing examples of software recently developed in Kotlin:<\/p>\n
