VS Code: Agent Host Consolidation
The Agent Host subsystem saw its biggest stabilization push yet, with a unifying connection factory, dependency bumps, and a cluster of session-lifecycle fixes across Codex, Copilot, and Automations. A second, separate wave of multi-diff virtualization fixes shipped twice after an incomplete cherry-pick.

Good evening, it's September 1st, and here's your VS Code development briefing.

Connor Peet's PR 333655 replaces six different ad-hoc ways of building remote agent connections with a single registered factory, fixing drift where fixes applied to one connection type never made it to the others. That same instinct—one code path…
Layered on top are three dependency bumps into that same system: xterm to 6.1.0-beta.303 in PR 333612, the Codex SDK to 0.149.1 in PR 333739, and the Copilot SDK to 1.0.13-preview.2 in PR 333198, which also migrated Agent Host to new permission-mode APIs. The Codex bump notably held back from version 0.152.0 due to…
Second theme: multi-diff editor virtualization. Hediet's fix in PR 333590 addressed scroll anchoring, height measurement, and disposed-model isolation in the virtualized diff view. It had to be reapplied in full via PR 333746 after an automatic cherry-pick, PR 333732, only carried over part of the patch—a caution…
