VS Code 1.138 brings agent sessions to Dev Containers

Microsoft released Visual Studio Code 1.138, adding agent sessions inside Dev Containers, expanded Codex support, and automated agent session cleanup. Agents run in the project's configured environment rather than the local machine; Dev Containers require Docker.

• Agent sessions can run inside a project's Dev Container when chat.agentHost.devContainer is enabled
• A Codex session can continue between the ChatGPT app and VS Code without losing the conversation
• Preview session cleanup auto-deletes merged sessions after a set number of days
• Agent automations are enabled by default and can be exported across environments
