Fleet 1.47

Fleet 1.47 has been released — JetBrains' next-generation code editor continues to evolve with enhanced code readability features, expanded AI chat capabilities, and meaningful quality-of-life improvements for daily development workflows.

What's New in Fleet 1.47

• Folding support for multiline comments — Fleet now supports folding multiline comments in the editor, reducing visual clutter when working with heavily documented code. Developers can collapse large comment blocks to focus on the logic while keeping documentation accessible with a single click.
• New AI Chat functionality — The AI assistant integration gets a significant upgrade with context-aware chat that understands your current file, selection, and project structure. Ask questions about code, request refactoring suggestions, or generate documentation — all without leaving the editor.
• Improved code readability — Enhanced syntax highlighting with better color contrast for deeply nested code, smarter indentation guides that respect project conventions, and improved bracket matching visibility across complex expressions.
• Performance optimizations — Faster file indexing on project load, reduced memory usage when working with large workspaces, and smoother scrolling in files exceeding 10,000 lines.

Refined Editor Experience

Fleet 1.47 brings several subtle but impactful refinements to the editing experience. The minimap now supports syntax highlighting, making it easier to navigate large files by providing visual context about code structure at a glance. Tab management has been improved with smarter grouping and better drag-and-drop reordering.

Search in files has been upgraded with support for regular expression lookaheads and lookbehinds, bringing Fleet's search capabilities closer to what power users expect from advanced IDEs. The results panel now groups matches by file with expandable sections for each file.

AI Features Deep Dive

The AI Chat in Fleet 1.47 is not just a simple Q&A interface. It can perform contextual actions like explaining a selected code block, suggesting optimizations, generating unit tests, and even writing commit messages based on staged changes. The chat panel supports markdown rendering for formatted responses, code snippets with syntax highlighting, and follow-up questions that maintain conversation history.

JetBrains has emphasized that all AI features are designed to be optional and respect local privacy — code analysis for AI features is performed locally by default, with cloud-based features clearly indicated.

How to Update

Fleet 1.47 is available through the JetBrains Toolbox App. Existing users can update directly from the Toolbox App interface. New users can download Fleet from the JetBrains website. Fleet remains in Public Preview, and JetBrains continues to gather community feedback to shape its roadmap.
