Compiling a lot of code fast is a hard problem, especially when the compiler has to perform complex analyses such as overload resolution and type inference with generics. In this post, I’ll tell you about a huge and largely invisible part of Kotlin which makes it compile much faster on relatively sm…
Today at the O’Reilly Open Source Awards 2019, we were honored to hear that Kotlin has won the prestigious Breakout Project of the Year award, this award recognizes a project that has started “breaking out in a big way” over the past year, which we are really happy about. We want to say a massive th…
With all the exciting recent events, we had to postpone the publication of the Future Features Survey results. Sorry about that. Better late than never, this blog post summarizes what we learned from the survey. To recap, the Future Features Survey ran in April and got about 850 replies. We would l…
We are happy to announce the first Technology Preview of Kotlin/Native that compiles Kotlin directly to machine code. The Kotlin/Native compiler produces standalone executables that can run without any virtual machine. It is not a fully functional release yet, but you can already play with the tech…
Congratulations! Today Kotlin 1.1 has reached Beta, and this means that it's time to try it out, there's still time to give us your feedback (and we really need it!), the release is coming fairly soon. We've seen a lot of interest in Kotlin over the past year, and would like to thank all our u…

It's been a month since we released Kotlin 1.0, and while our user base roughly doubled during this time, we prepared the first bugfix update. Kotlin 1.0.1 starts a series of 1.0.X versions delivering safe bug fixes and performance improvements to the language (as well as other parts of the project…
This is it. 1.0 is here! It's been a long and exciting road but we've finally reached the first big 1.0, and we're celebrating the release by also presenting you with the new logo: See the discussions on Reddit and Hacker News. (more…)…
Finally, Kotlin has graduated the Beta and we are happy to present the Release Candidate Build! NOTE: as we announced earlier, RC requires all code to be recompiled to make sure no code compiled with older versions is kept around (please recompile even if you were on the EAP version!). This blog p…
We are glad to present another update of Kotlin 1.0 Beta. We are working towards finalizing the standard library and getting rid of old deprecated constructs in the language, as well as bug fixes, performance improvements and future-proof checks. Full list of changes is available here. See closed i…
The first update to our Beta is here! We are stabilizing, so it's mostly bug-fixing and changes to the standard library. Language changes We are now enforcing single-instantiation inheritance constraint on type parameters: the same T can not have both List<Int> and List<String> as its …
