• Image understanding: Images are now supported in SWE 1.5, enabling visual content analysis

Features

Improvements to SWE-1.5 + Claude Sonnet 4.5 Mode

Enhanced the SWE-1.5 + Claude Sonnet 4.5 mode with improved performance and reliability for better coding assistance.

Features

Expanded Codemaps

Codemaps now include powerful new capabilities:

• Chat with map - Interact directly with your codebase visualizations
• Mermaid diagrams - Generate visual diagrams within maps for better code understanding
• Cascade suggestions - Get AI-powered suggestions directly in your maps
• Map option in chat/edit nudges - Easily create maps from chat and edit interactions
• Smart mode option - Enhanced intelligent assistance when working with maps

Cascade Summarization Fix

Improved Cascade summarization to better handle longer conversations. Previously, summaries could be too aggressive and drop important context. Now maintains better continuity across long sessions with multiple file changes and user messages.
