Spring Boot provides comprehensive externalized application configuration support. It enables one application artifact to run in different environments by supplying values from various sources such as: In this article, we’ll explore the best practices for managing Spring Boot application configuration. A well-designed configuration strategy should ensure that: Configuration properties…
The 2026 Django Developers Survey (results coming soon!) found that AI is part of the weekly or daily workflow for 90% of respondents. AI can write code quickly, but Django developers still need to understand the application, evaluate what the agent produces, and be accountable for what ships. That makes your IDE more important, not […]
Go 1.27 is here, and the release notes have plenty to explore. Language updates include generic methods, promoted field names in struct composite literals, and improved function type inference. Beyond the language itself, Go 1.27 expands go fix with new modernizers and adds a profile for finding goroutine leaks. These updates touch many parts of […]
You can now use Air with your existing Claude Pro, Max, or Team subscription. Usage counts against your subscription quota – there’s no need to purchase API credits and no per-token Console billing. Login goes through Anthropic’s own authentication flow. Air never sees or stores your credentials. This was our most-requested feature and it took […]
Here’s a function that signs a document: In Kotlin, Unit means the function completes without returning a meaningful value – roughly equivalent to void in Java. Got it? Now, tell me what could go wrong. You can’t. Yet, the code might be invalid. The signing window might have closed. The database might be down. The […]
We traced a frontier model through fifteen C# refactoring tasks and counted what it reached for. It piped text into interactive commands 468 times. It called git 422 times and sed 392 times. It ran dotnet build 163 times. Across 2,513 tool calls it performed a structural refactoring operation exactly zero times. Not because it […]
Our first minor update for the 2026.2 release cycle is ready to download. Here’s what’s new. Rider Rider 2026.2 put AI-assisted development front and center, and v2026.2.1 keeps that momentum going: The refactoring-code skill, bundled in JetBrains Rider Median task time before: 157.9s → after: 26.6s 83% faster Cost per solved task before: USD 0.52 […]
Across the PyCharm 2026.2 release line, we shipped 263 fixes and improvements. Many improve Python code insight directly, with more precise type inference, fewer false positives, smarter completion and imports, and more reliable refactoring. Here are some of the smaller changes you’re likely to notice in everyday Python development. SQLAlchemy 2.0 support SQLAlchemy has been […]
Atlassian recently announced that they are suspending sales for Data Center Products, followed by the end of life for those products in 2029. Additionally, this August, Atlassian began using certain customer data to improve its AI experiences. In light of these changes, switching to an alternative solution has become a priority for many organizations. Around […]
Based on the Developer Ecosystem Survey 2026, the tenth edition of our large-scale, globally representative study run by the Strategic Research and Market Intelligence team. This post picks up where our previous report on the adoption of the main AI coding tools left off in April 2026. We recently ran the Developer Ecosystem Survey 2026 […]
Toolbox App 3.7 enables JVM memory optimization by default, improves the reliability of updates and session expiration recovery, and ensures compatibility with Windows Smart App Control. Action required: Update Toolbox App on Windows If you’re using an older version of the Toolbox App (3.4 or earlier) for Windows, update to v3.7 or later to keep […]
Modern software development teams face a difficult balancing act. Applications are growing more complex, release cycles are accelerating, and security expectations continue to rise. This is especially true in a time where much more code is generated daily, which needs to be checked. Teams need tools that can identify vulnerabilities early without creating additional friction […]
Starting a new job is exciting, and there’s a lot to take in. At JetBrains, onboarding doesn’t stop after your first day. It starts when you accept your offer and continues through your first months, giving you the information, tools, and support you need to settle in and start doing your best work. Here’s what […]
Explore a growing Kotlin Multiplatform catalog in your browser, or bring up-to-date library data directly into your AI development workflow through the klibs.io MCP server. When we introduced klibs.io in December 2024, the goal was simple: make it easier to find a Kotlin Multiplatform library that fits both your use case and target platforms. Since […]
Google’s most capable Flash model for coding, with a limited time discount. Most of the coding you do in a day doesn’t need a flagship model. It needs a good one that won’t have drained your budget by lunchtime. That’s the thinking behind Junie’s new default, Gemini 3.7 Flash. It’s live now in both the […]
Something is happening in server-rendered web development. React shipped Server Components. HTMX made “hypermedia” cool again. Phoenix LiveView proved a server can push interactive UI updates without a client framework in sight. Every ecosystem seems to be rediscovering the server as a place to render UI, except one: the JVM. What if Compose, the UI […]
Open weight models are having a moment, driven by control, choice, and cost. Hybrid and local AI are now getting serious looks, so JetBrains teamed up with DeepLearning.AI on a free AI Coding Workflows: Hybrid to Local course that covers the ideas and options. The course is now available and uses PyCharm and its AI […]
A developer in DevOps pushes a Kubernetes deployment with no resource limits, a pod running as root explicitly, and a GitHub Actions workflow runs with mutable tags – and it goes straight to production, unnoticed. No quality gate. No IDE warning. No CI failure. An innocuous change, silently shipped, but with high consequences. Qodana lints your application code. It catches unused variables,…
TL;DR: This post relates findings about language migration from the 2025 State of Developer Ecosystem survey. In general, project requirements are still the most common reasons for switching languages. One outlier from this trend, however, is Kotlin. People switch to Kotlin not because they have to; they switch because it simply feels better to work […]
The Agent Client Protocol (ACP) defines a common contract between a client – like IntelliJ IDEA – and an agent. IntelliJ IDEA already includes several ACP-compatible agents: Codex, Claude Agent, and Junie. Beyond these bundled options, the ACP Registry provides more choices, and teams can register internal or unlisted agents through acp.json. The key idea […]
This PyCharm release is a big one for anyone building with AI. Your agents can now roll up their sleeves inside your Jupyter notebooks – working against a live kernel instead of firing off disconnected scripts. And they finally know which Python to use, so packages land in the right environment every time. We’re also […]
AI agents are supposed to save you time. Ask one to install a dependency or run your project, though, and it often does the opposite: It installs into the wrong Python, ignores the uv or virtual environment your project uses, and hands back a broken setup for you to fix yourself. PyCharm’s new Agent Environment […]
If you’ve handed notebook work to an AI agent, you know how it tends to go: More often than not, it corrupts your .ipynb, loses your trained model the moment the run finishes, or burns budget sitting idle through a long job while you watch. To solve this, we’re introducing a brand-new Jupyter skill. Built […]
As part of ongoing maintenance, we are unbundling and deprecating low-usage plugins starting with PyCharm 2026.2. This includes support for Data Wrangler, Hugging Face, and Google Colab, among others. A more focused set of bundled plugins means a leaner codebase, enabling us to keep PyCharm fast and responsive and invest our effort where it has […]
