# Java Annotated Monthly – October 2026 > Source: > Published: 2026-10-05 13:05:48+00:00 ## IntelliJ IDEA IntelliJ IDEA – the Leading IDE for Professional Development in Java and Kotlin [News](https://blog.jetbrains.com/idea/category/news/) # Java Annotated Monthly – October 2026 September gave us plenty to talk about, with major releases and thought-provoking reads. Java 27 arrived, and JetBrains opened a new chapter in agentic development with the announcement of JetBrains Air, a system of products for agentic software development, followed by the EAP of JetBrains Air in IDEs. [Marit van Dijk](https://maritvandijk.com/) kicks off this edition with her favorite news of the month and a closer look at these highlights. Then comes our usual selection of news, tutorials, and community stories. Let’s dive in! ## Featured Content [Java 27](https://openjdk.org/projects/jdk/27/) was released last month. Of course, we support it from day 1 in IntelliJ IDEA. You can read all about it in [Java 27 in IntelliJ IDEA](https://blog.jetbrains.com/idea/2026/09/java-27-in-intellij-idea/) or watch the [release stream](https://www.youtube.com/watch?v=4V2jooUo8O0) if you missed it. [Piotr Przybył](https://softwaregarden.dev/en/) and I updated our talk [Learning modern Java the playful way](https://maritvandijk.com/presentations/modern-java-playful/) and [presented](https://gotocph.com/2026/sessions/4000/learning-modern-java-the-playful-way) it at [GOTO Copenhagen](https://gotocph.com/2026) last week, where I was also on stage for two other sessions.
