# Claude Code 2.1.274

By Steven Van · 2026-09-16

Version 2.1.274 warns on critical memory use, lets non-interactive runs cap MCP startup waits, and fixes a stuck-retry bug.

Claude Code 2.1.274 adds a warning when memory usage gets critical, with steps for freeing memory or restarting safely.

- A new CLAUDE\_CODE\_MCP\_STARTUP\_WAIT\_MS environment variable bounds how long the first non-interactive turn waits for MCP servers to connect (set to 0 to skip waiting).

- Collapsed teammate and agent messages can now be expanded with a click in fullscreen mode.

- Sessions no longer get stuck endlessly retrying on an "unexpected tool\_use\_id" 400 error.

- Several additions for enterprise deployments: an effort attribute on the LLM request telemetry span, a new OpenTelemetry event for managed-settings resolution, a configurable Postgres connect timeout for the Claude apps gateway, and IdP subject data in telemetry sent by Claude Desktop and Cowork.
