Did you know IntelliJ IDEA inspections for #Kotlin coroutines can help prevent issues in your code? They catch: 🔎 Misuse of `SupervisorJob()` 🔎 `runBlocking` in `suspend` functions 🔎 Shadowed `coroutineContext` 🔎 And more! Read the guest post by @marcinmoskala 👇 blog.jetbrains.com/idea/2026/03/i…

📢 Kotlin 2.3.20 is out! Here are some of the highlights: ✅ Gradle: Compatibility with Gradle 9.3.0 and Kotlin/JVM compilation uses BTA by default. ✅ Maven: Simplified setup for Kotlin projects. ✅ Kotlin compiler plugins: Lombok is in Alpha and improved JPA support in the kotlin.plugin.jpa plugin. ✅ Kotlin/Native: New interoperability mode for C. ✅ Language: Support for name-based destructuring declarations. ✅ Standard library: New API for creating immutable copies of map entries.

Once upon a time, JetBrains IDEs and their plugins had UI freezes… 😱 But fear not — there is the cure. Join me on YouTube soon to figure this out! info.jetbrains.com/marketplace-li…

I am so proud and happy to finally see this warning in IntelliJ!

The @SpringData JDBC is growing and IntelliJ IDEA provides first-class support for it! ✅ Create entities from DB tables ✅ Generate scripts for @liquibase / @FlywayDb ✅ Create repositories from usage + auto-wiring ✅ Column-to-code completion Read more 👇 blog.jetbrains.com/idea/2026/01/s…

When you hear JPA, you think #Java. But what about #Kotlin? This code looks correct, but a DB-generated ID changes after save() and entities disappear from HashSet/Map. Val and non-null types give false guarantees due to the reflection. How to avoid it 👇 jb.gg/3cn6mp

IntelliJ IDEA turns 25! 🎉 Join the celebration to meet our special guest Runzo, play with him, and grab our one-of-a-kind birthday postcards. Join the celebration! 👇 jb.gg/IJ25

🚀 Benchmark smarter with kotlinx-benchmark and Kotlin Notebook! Load results as DataFrames, explore them interactively, and visualize performance with charts – all in one place. Learn more in the blog post 👇 blog.jetbrains.com/kotlin/2025/12…

Kotlin Notebook makes Advent of Code puzzles a breeze, thanks to: ✅ Interactive Kotlin ✅ 2D data handling with Multik ✅ Live visualizations ✅ Easy GitHub Gist sharing See how fun puzzle-solving can be ⤵️ youtube.com/watch?v=nWPYGH…

Huge effort by marvellous team! Exited for the future of Kotlin support

Spring Boot 4 now has automatic context propagation for @Kotlin coroutines 🎉 Trace context flows inside coroutine execution, making async code simpler and ensuring seamless integration – all in the familiar Spring ecosystem. Try Spring with Kotlin 👉kotl.in/vk4h77

@IlyaMuradyan @kimbetti @intellijidea And also, do you use "Attach to Running Kernel" or "Run in Separate Process"?

@kimbetti @Teodor_ai @intellijidea I see, thank you! Could you please share some minimal notebook example for us to investigate?

The IntelliJ IDEA 2025.3 release has landed! This version brings several significant updates, all of which are described and demoed on our What’s New page. Check it out! 👇 jetbrains.com/idea/whatsnew/

@kimbetti @intellijidea To check which kernel version you use: Setting the button on the top, and then "Kernel version". Could you share the selected one with us, please?

@intellijidea This release seems to have broken a lot of my notebooks. On top of that it no longer prints the actual exception so there is no way to know what is wrong

portable gaming? more like portable coding

I turned a gaming handheld into a coding workstation. 🤯 ❌ No Keyboard ❌ No Mouse ✅ Just @IntelliJIDEA, @Kotlin Notebooks, and AI Watch me build a Pong game from scratch using only a gamepad and voice-to-text: youtube.com/watch?v=I6wYBt…

What does it look like when you take ✨ Kotlin Notebooks ✨ and solve #AdventOfCode Day 3? Well, it looks like this! @volebamor created this viz live on our stream that just finished. 🎨 Nothing even comes close to @Kotlin Notebooks when doing this stuff.

Thanks @toldoven for the framework! I can't wait for the rest of Advent, this year only 12 tasks though.

✨ Tip: Kotlin Notebook is a great way to tackle the challenges, letting you iterate quickly on solutions. With the community‑built github.com/Toldoven/aoc-k… framework (thanks, Toldoven!), you can open a problem and start solving it in one click. In past years, hundreds of participants have relied on it to tackle AoC, as shown by GitHub repos.

🎄 Join us live for five days of Advent of Code puzzles and five Kotlin livestreams on December 1–5! Solve the puzzles in Kotlin with help from Kotlin team experts and fun community guests, climb the leaderboard, learn new tricks, and have a chance to win some prizes along the way! 💜 kotl.in/aocx25
