Nice collaboration with @marcinmoskala 🙏

We released air.dev — a new Agentic Development Environment by JetBrains. Claude, Gemini, Codex, and Junie side-by-side with you — powered by code insight, beautiful UI, and vast development tooling. But underneath there's a technological iceberg. Let me walk you through it. 🧵

Celebrating @intellijidea 25th birthday at #javaone

Destructuring has been a popular feature in Kotlin, but since it's been based on position, it comes with some risks. But with Kotlin 2.3.20, you can eliminate many of those risks! Here's what I mean... Since destructuring is based on position, the order of your variables needs to match the order of the components (such as the data class constructor properties). If you accidentally swap around a few of them, you could end up with some surprises, and it's easy to do, especially when several of the components have the same type! But with Kotlin 2.3.20, you can now enable an experimental feature to use name-based destructuring instead! When activated in "complete" mode, the syntax we've been using up until now will match based on name rather than position. This means you can get them out of order, and it still works. If you use a name that doesn't match, you'll get a compiler error. But for those cases where you actually wanted a different name, you can use a new syntax to assign the component to a different name: val (title, cost = price, author) = book Prefer to use the classic, position-based destructuring? You can use brackets instead of parentheses, like this: val [author, cost, title] = book The bracket syntax brings along some connotations of collections, which seems fitting, since position-based destructuring could still be helpful for things like Pair and List. It's still experimental, and there's a full migration path planned out, but you can activate it today with a compiler argument. What do you think about this feature Do you like the new syntax? Have you run into issues with position-based destructuring in the past? #Kotlin #AndroidDev

Каждый раз умиляюсь, как мамкины журналисты додумывают ситуацию, чтобы она стала «погорячее», и несут пургу с уверенным видом похлеще любого ИИ. Чего не сделаешь ради подписоты! На самом деле всё было, конечно, так: - Сработала сигнализация; - Коллеги в соответствии с инструкцией вышли на улицу и собрались в точке сбора; - С телефона написали в канал сообщение; - Glean сказал, что всё норм, можно сидеть на своих местах; - Приехали пожарные. Но это же так скучно! Давайте додумаем за автора!

Anna Kozlova, Technical Lead for the IntelliJ IDEA Kotlin Plugin at JetBrains, joins KotlinConf’26! She’ll discuss how your Kotlin code can have a surprising impact on IDE performance, and how small changes in your code style can lead to noticeable improvements. #speakers" target="_blank" rel="nofollow noopener">kotlinconf.com/#speakers

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

Command completion (..) extends regular code completion. In addition to API completion and postfix completion, code completion now includes commands. To filter the list to commands only, use .. The list is searchable, to help you find what you need more quickly. #IntelliJIDEATips

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

Premiering in @IntelliJIDEA – a new way to invoke IDE actions! You can use navigational and other features directly from the code completion popup, or type period (.) twice to get only the list of actions. If you like this feature, we’ll be sure to bring it over to other IDEs!

Goodbye K1 mode! 👋 IntelliJ IDEA 2025.3 deprecates Kotlin K1. K2 now powers the IDE via the Kotlin Analysis API. This means: ⚡ Faster analysis on large projects 🧱 Stable foundation for evolving Kotlin support 🛠️ Improved stability More in the blog 👇 blog.jetbrains.com/idea/2025/12/t…

🚀 The unified IntelliJ IDEA 2025.3 is here – no need to choose between Community Edition and Ultimate! Update now for: ✅ Simpler setup and updates in one IDE ✅ Smoother development ✅ More free features Full details 👇 jb.gg/idea-unified-r…

So, today I found out about a secret, unsafe, internal property that makes Hot Reload waaaay faster. Like lightning fast. Even in a real project, not just with Hello World. We're currently discussing if y'all are ready for this yet - we'll probably add it to guidance later.

I'm always surprised by how many people don't know about the Kotlin Slack community. It's a fantastic place to discuss issues with others, with dedicated channels for almost any Kotlin topic, and lots of JetBrains people monitoring them too.
