Copilot Chat v0.43.2026033101: WebSocket & Telemetry

TL;DR

  • One WebSocket per conversation for better isolation and reliability
  • Workspace metadata (git branch, commit, remote) now sent to telemetry
  • Fixed whitespace-only text blocks and conversation cleanup issues

New

  • One WebSocket per conversation — Each conversation now gets its own WebSocket connection instead of sharing, improving isolation and reducing cross-talk issues.
  • Workspace metadata in telemetry — Git branch, commit hash, remote URL, and file paths are now included in OTel events and GitHub telemetry for better debugging and analytics.
  • Copilot CLI Controller API — New API for controlling Copilot CLI from extensions.
  • Model selection for coding tasks — Copilot coding agent now respects your selected model when starting tasks.

Fixed

  • Whitespace-only text blocks from orphaned CacheBreakpoint — Removed spurious empty blocks that appeared in chat.
  • Conversation store cleanup — Sessions are now properly disposed and removed from the store when closed.
  • Workspace changes handling — FolderRepositoryManager now clears workspace changes before retrieving modified files.
  • Background compaction between tool calls — Fixed issue where compaction wasn't being applied during multi-step operations.
  • Skill directory access — Resolved permission issues accessing skill directories.

Breaking Changes

  • Claude co-attribution disabled in commits/PRs — Claude is no longer attributed in generated commit messages and pull requests.

Other

  • Session context keys updated to new standard
  • Discard changes action now shown only when appropriate
  • Base branch selection prefers upstream when available
