Copilot Chat v0.41.2026031902: PDF & Multi-File Support

TL;DR

• PDF document support added for Anthropic Claude models
• Multi-file cursor jump now works in NES (Nested Editor Sessions)
• Chat repository tracker added to monitor manual edits during sessions

New

• PDF document support for Claude — Anthropic Claude models can now process PDF documents directly in chat, expanding what you can analyze without manual conversion.
• Multi-file cursor jump in NES — Jump between files in nested editor sessions without losing context.
• Chat repository tracker — Automatically tracks manual edits and changes made while a chat session is in progress, giving you better visibility into what changed.
• TypeScript context provider enabled by default — Better TypeScript support out of the box without manual configuration.
• Search subagent path resolution — Handles both relative and absolute paths in search subagent queries.
• Image URI in prompts — When rendering images, the LLM now receives the URI for reference in downstream tools like artifacts.

Fixed

• Cloud agent timing — Fixed per-session created_at timestamps for accurate cloud agent performance metrics.
• View image tool for Claude — No longer deferred, improving response speed for image-related queries.
• Search subagent retry logic — Added retry on first external ingest search failure to improve reliability.
• Telemetry timing — Enhanced telemetry now waits for user idle state before sending, reducing noise in event logs.

Under the Hood

• oTel instrumentation for Claude CLI — Added OpenTelemetry instrumentation to Claude CLI sessions in Agent Debug panel for better observability.
• System prompt updates — Updated to handle search subagent integration.
• Debug event log hooks — New hooks added for debugging event logs.
