2025.2 버젼 업데이트

기능

• AI Assistant
  • Code completion for ERB - Cloud-based code completion for ERB has been expanded. It now works within ERB tags, such as <% <caret> -%> and <%= <caret> %>.
  • Stronger project awareness in AI chat - AI Assistant chat now leverages the Search Everywhere functionality for Classes and Symbols to incorporate more accurate context.
  • Project rules for consistent AI guidance - You can now define project-specific instructions that guide AI responses, such as coding style or framework constraints. Rules are stored inside your project and can be shared across the team, ensuring alignment and consistency without repeated manual input.
  • More ways to connect local models - AI Assistant allows you to work with local models by connecting third-party LLMs running on your machine. In addition to Ollama and LM Studio, you can now use any model server compatible with the OpenAI API, such as llama.cpp, LiteLLM, and others. This lets you take advantage of AI-powered features for free, with no data leaving your machine.
  • Image attachments - JetBrains AI Assistant now supports image attachments in the chat when using Anthropic and OpenAI models.
  • Expanded and improved code suggestions - In RubyMine 2025.2, AI Assistant will deliver more code suggestions across a wider range of contexts, streamlining your development workflow. Additionally, improvements to the formatting of multiline outputs provide a more refined coding experience.
• Junie
  • Now 30% faster.
  • MCP support is now available: The Model Context Protocol allows Junie to connect external sources like databases, file systems, or APIs. This improvement makes Junie significantly more useful in practical scenarios. LLMs and agents are often limited by their lack of access to real-world context and tools. The MCP addresses this by connecting Junie to external servers.
  • Junie is now integrated with Remote Development: You can work remotely with your team - and delegate tasks to Junie at the same time.
• Ruby
  • More customization options for code inspections - RubyMine 2025.2 allows you to disable specific type signature providers used for certain code inspections. This can be particularly helpful in cases where an inspection uses data from a few services and you want to avoid conflicts between them.
• Rails
  • Better performance while editing migration files - Working with Rails projects that contain numerous migration files is now much more fluid. RubyMine 2025.2 ensures that edits, additions, and deletions of migrations happen without delays or freezes, keeping your workflow uninterrupted.
  • Faster project startup - This release has optimized how certain background tasks are handled during project startup. By delaying some operations and reducing how often others run, this makes project startup quicker and smoother, allowing you to get started on your work faster.
• RBS
  • Hover hints for RBS - RubyMine 2025.2 now supports hover hints for RBS declarations and references. Press Ctrl and hover over a declaration in an .rbs file to see a preview of the target. This preview is particularly helpful for quick, in-context insights into a reference's target. For example, you can use it to view the definition of a type alias without navigating to it.
  • RBS Collection integration enabled by default - Improved type support with RBS Collection is now enabled by default. You'll notice improved precision in features such as:
    • Find Usages.
    • Rename refactoring.
    • Inlay hints when viewing source code with type signatures.
  • Note: The RBS Collection integration requires RBS 3.2, which comes bundled with Ruby 3.4. If you're using an older Ruby version, RubyMine will prompt you to install the appropriate gem.
• Bundler
  • Fewer notifications, fewer distractions - RubyMine now groups missing gem notifications across all modules into a single alert, reducing clutter and interruptions.
  • Customizable Bundler setup - To save you from dealing with dialogs each time you invoke a Bundler command, this release has introduced a new Bundler tab. Located under Settings | Tools, it allows you to:
    • Automatically install the required Bundler version.
    • Set default arguments for all future Bundler commands.
  • New installation workflow - RubyMine now installs gems one module at a time to prevent conflicts and avoid reinstalling gems shared between multiple modules.
• Code insight
  • Improved exception-constant completion - This release has optimized how RubyMine handles code completion for exception constants. In cases where no prefix is provided (for example, when triggering autocompletion without typing), the suggestions are now limited to a focused set of relevant constants.
• User experience
  • Non-modal RubyMine debugger installation - In RubyMine 2025.2, the process of installing debugger gems is non-modal, with progress displayed in the terminal window instead of the progress bar.
  • Ruby support in Qodana - RubyMine powers the newly introduced Ruby linter in Qodana. The Ruby linter brings RubyMine's robust code inspections into automated workflows, helping you catch issues and maintain high code quality across your projects. Qodana for Ruby is currently in Early Access.
