Good morning, it's September 28th, 2026. This is VS Code Daily.
Lead insight: this cycle was dominated by disposal hygiene — a sweep to stop listeners, caches, and buffers from outliving the UI or request that created them.
First theme: plug the leaks. Webview resource loading in PR 338306 now scopes cancellation to each request instead of sharing one emitter, so file reads end cleanly when streaming finishes or the webview is disposed. In the editor, PR 338358 shares one theme listener for semantic tokens and PR 338361 does the same…
Second theme: make agent sessions predictable. PR 337659 blocks sending when another app holds the Codex conversation lock, showing a persistent banner while preserving drafts and history. PR 333955 stops idle Dev Containers and restarts them on demand, and PR 338206 adds correlated startup telemetry to compare…
What's next: watch memory telemetry on long sessions and Insiders feedback on the simplified Draw progress style and managed sandbox controls.
That's it for today. Thanks for listening.
