We've just shipped Java and Kotlin by IntelliJ IDEA 1.0 – our LSP-based extension’s first stable release for VS Code and Cursor.
@MarcoBehler, Head of JVM Ecosystem, breaks down why it matters, what’s in 1.0, and what’s next👇

1/3 Air Desktop app
The standalone Air app is no longer available for download.
If you already have it installed, we’ll keep delivering updates for some time, but please consider this temporary.
Thank you to everyone who tried the Air app and told us what worked and what didn’t. That feedback is what led us here.

"I love exceptions," says Ronald Dehuysser, creator of JobRunr. In our latest episode, he shows how to run reliable background jobs in Java with Spring Boot, from automatic retries to carbon-aware scheduling.

IaC is dead.
Sorry DevOps / SREs / Cloud Engineers but you're in for the same roller coaster as Devs. AI can manage infra change better than you.
Unfortunately for IaC, we don't need code because with the actual system source code and the infra, AIs have everything needed to determine change sets / approvals and dev env lensing.
btw, Effect Oriented Programming probably will help you get there; but that is inevitable for your codebase.

To complete your code, just dot dot!
Command completion is an easy new way to access context-aware IDE actions, right where you’re coding.
Whatever OS you use and however you work, you just need two taps of one key.

Your AI coding agents will feel right at home in the JetBrains terminal.
Multi-line prompts, light/dark theme matching, and cleaner TUI rendering, all thanks to libghostty 👻
And it’s not just for agents. Neovim and tmux now follow your IDE theme, keybindings work the way the docs say, and ncurses apps, monitors, and dashboards now render borders, colors, and lines cleanly.
On by default in the 2026.3 EAP builds. Learn more 👉 jb.gg/jb-terminal-with-libgh…

JetBrains IDEs are now powered by libghostty! This brings huge feature and performance improvements to JB terminals! Based on their own annual reports, that's over 12.5 million active users across all platforms about to get a libghostty-powered terminal. blog.jetbrains.com/platform/…
I'll repeat myself: libghostty is and was always the primary goal of the Ghostty project (I said this in the first public talk I ever gave about Ghostty). The importance and impact of a free, liberally licensed, high quality terminal emulator library that runs anywhere and everywhere dwarfs any single terminal emulator application on its own.
I've estimated Ghostty's (GUI, not libghostty) own users at around a couple million. Overnight, 6x that are using a libghostty-powered terminal. From one integration.
Happy to see this, happy to hear JetBrains had a positive experience, and looking forward to continuing to improve and ship a stable libghostty tag soon!

The same engine that powers IntelliJ IDEA, at work with no IDE open. See how its code intelligence helped AI agents to be more efficient.
JetBrains IDE intelligence made coding agents 20%–30% more efficient.
Netflix gave AI agents JetBrains IDE intelligence, ran headless, and measured typical gains on real Java and Kotlin tasks, with no drop in correctness.

Java and Kotlin by IntelliJ IDEA has reached 1.0!
Built together with @cursor_ai, this LSP-based extension release is a major leap toward bringing our JVM technology beyond the IDE – wherever you’re working, whichever editor or agent you use.

This is big. The benchmarking game of agents, skills, models, and combinations of all of them has been a fun topic to follow. Not so many companies share real-life figures, though. Kudos to Netflix! They did a great job experimenting and measuring the effect of the code intelligence tools on the agents. I wish we could see more studies like this from other big companies, too.
From the article: "Typically 20–30% more efficient (fewer tokens, less time), and up to about 65% in the best case"
So yeah, it's useful to teach the new dogs (agents) old tricks (IDE tooling) for better efficiency.

Not sure what I was saying there, but @gAmUssA is cringing out :)
@dDoutsiopoulos thank you for the best pictures, as usual, and thank you @Devoxx for having us!
