Scala 3.8 Support in the Scala Plugin: - The `into` modifier - Scala 3.8 requires JDK 17+ - “Better fors” - Basic support for capture checking - The `runtimeChecked` method

We’re now working on our next major release, which we plan to deliver in March. In our latest stable version (v2025.3), we introduced many features and enhancements, so for the next release, we’ve decided to focus on maintenance and bug fixes rather than introducing new functionality. With that in m…

Thank you to everyone who participated in Advent of Code 2025 in Kotlin! Once again, it was a joy to see so many of you sharing solutions, cheering each other on in Slack, and keeping the holiday coding spirit alive. This year, we kicked things off with five days of livestreams on December 1–5, w…

Happy New Year and welcome to the first Java Annotated Monthly of 2026! We hope this year brings fresh ideas, smarter ways to stay productive, and innovation that lasts.

We introduced TeamCity Pipelines in March 2024 to make CI/CD setup simpler and more intuitive, without limiting what teams can build and automate. Pipelines brought a new workflow focused on a more guided configuration experience, including a visual editor with drag-and-drop dependencies, YAML for d…

This is the second guest post in a two-part series from José Luis González.

TL;DR Fleet은 원래 JetBrains의 차세대 IDE를 탐구하려는 시도였으며, IntelliJ 플랫폼 기반 제품 개발과 병행하여 개발되었습니다. 하지만 시간이 지나면서 두 가지 범용 IDE 제품군이 혼란을 주고 주의를 분산시킬 수 있다는 사실을 깨달았습니다. IntelliJ 기반 IDE의 모든 기능을 Fleet에 다시 구현하는 것은 충분한 가치를 창출하지 못했으며, Fleet을 단순히 또 다른 에디터로 포지셔닝하는 것만으로는 중복되는 두 제품 라인을 유지할 이유가 되지 못했습니다. Fleet은 2025년 12월 22일부터…

At KotlinConf'25, global brands like Meta, AWS, Duolingo, and Uber shared real-world engineering stories.

As engineering teams scale, so do the demands on their tooling. Code quality checks that worked well for one repository or service often need a more resilient, automated, and infrastructure-native setup when development ecosystems grow. That’s exactly why we’re excited to introduce first-class K…
