Someone pinning Copilot coverage from GitHub’s Supported IDEs table would take VS Code 1.107.1 and Copilot Chat 0.35.3. That is still the floor. I fetched the live page; it now lives under billing-and-usage. No 1.139.0 on it.

The changelog from today says several IDEs moved Copilot agent sessions onto the Copilot SDK, and those sessions did not say which IDE they came from. Agent activity and agent lines of code (loc_added_sum / loc_deleted_sum for agent_edit) were undercounted, and some of it was counted as Copilot CLI. Billing unchanged. No backfill. VS Code 1.139.0 and later send the identity again; Visual Studio 18.12 is expected this month, JetBrains late October, Eclipse and Xcode by November. I didn’t call the metrics API.

The reconciling page still says CLI metrics (daily_active_cli_users, totals_by_cli) are collected separately from IDE telemetry, and that CLI usage does not contribute to IDE counts.
