Claude Code release notes: 2.1.318 shows login expiry

Claude Code 2.1.318 now shows when a stored claude.ai sign-in expires. For people running recurring jobs, this provides a chance to renew the login before the next run fails.

Claude Code exposes expiry dates and advance warnings

Human step: Run claude auth status in your terminal. In version 2.1.318, the result includes the expiry date in loginExpiresAt.

In JSON results from claude -p, which runs Claude without an interactive conversation, the field is named credential_expires_at. Runs using text output also receive a warning on the standard error stream, stderr, starting ten days before the stored login expires. A job that saves only standard output therefore needs to capture stderr as well to retain that warning.

When the login has expired

The error message now says that the stored login has reached its time limit. In claude -p mode, it points to claude auth login and claude setup-token. The update does not renew the login automatically; it makes the expiry date and reason for failure clearer.

This applies to stored claude.ai sign-ins. The release note does not describe an equivalent time limit for API keys.
