GitHub Copilot in VS Code April Releases: v1.116–v1.119

TL;DR

• Semantic search now works across any workspace; agents can grep GitHub repos and orgs
• Agents gain inline diffs, browser tab sharing, terminal read/write access, and bring-your-own-key model support
• Experimental /chronicle feature lets you search your chat history to recall past work and PRs
• Copilot CLI sessions can now be monitored remotely from GitHub.com or mobile

New

• Semantic search across any codebase — Agents can now index and search all workspaces, plus run grep-style queries across GitHub repos and orgs with the new githubTextSearch tool.
• /chronicle (Experimental) — Query your local chat history to recall recent work, files touched, and PRs referenced. Enable via github.copilot.chat.localIndex.enabled.
• Inline diffs in chat — Code changes now render as diffs directly in the chat thread instead of separate views.
• Bring your own model key — Copilot Business and Enterprise users can link API keys from OpenRouter, Microsoft Foundry, Google, Anthropic, OpenAI, and others. Run models locally with Ollama or Foundry Local. Admins control access via group policy.
• Agent terminal access — Agents can read from and write to any open foreground terminal, including REPLs and interactive scripts.
• Browser tab sharing — Share live browser tabs with agents on demand. Agents can read content, interact with pages, and validate changes in real time.
• Remote Copilot CLI monitoring (Experimental) — Monitor and steer ongoing CLI sessions from GitHub.com or mobile. Enable github.copilot.chat.cli.remote.enabled and run /remote on.
• Persistent agent debug logs — Debug logs now persist locally across sessions so you can retrace earlier agent runs.
• Background command notifications — Long-running terminal commands surface status updates as system notifications in chat.
• Token usage optimization — Smarter prompt caching, deferred tool loading, and purpose-built agentic tools reduce token consumption without changing agent behavior.

Improved

• Incremental chat rendering for faster response display in agent sessions.
• Sortable agent sessions and synced session titles for Copilot CLI.
• Markdown preview toolbar with new buttons and commands to switch between source and preview.
