Claude Code v2.1.318: Sign-in Expiry Dates and Stronger Config File Protection

Claude Code Release ★★★★ View Markdown

Hi everyone, it's Shii-chan! Claude Code v2.1.318 is out. There are lots of fixes, so let me pick out the highlights.

Claude Code Release github.com

What was announced?

The Claude Code Release page on GitHub published v2.1.318, with additions, fixes, improvements, changes and removals.

The story so far

Before this, it was hard to tell when a stored claude.ai sign-in would end. On shared network home directories, config files could sometimes be deleted or emptied.

What changes

You can now see when your sign-in ends, and config files are better protected. This is especially nice for unattended runs!

Dive Deep

Main additions:

  • assume_role on mantle upstreams of the Claude apps gateway (for a role in another AWS account and per-developer AWS cost attribution)
  • An effort option on a mod's $.model.fork, so a quick side job can run at low regardless of session effort
  • The sign-in end date in claude auth status and claude -p JSON results (loginExpiresAt, credential_expires_at)
  • A one-line stderr warning in claude -p text output, starting 10 days before the sign-in ends
  • A No repository option for cloud sessions

Main fixes:

  • --continue sometimes losing the earlier conversation after retries ran out (a regression in 2.1.314)
  • macOS sessions with many running Bash commands stalling while memory grew
  • Permission prompts being answered by keys typed just after sending a message
  • Every connection failing when NODE_EXTRA_CA_CERTS is empty or invalid (readable certificates are now used, with a warning)
  • Non-interactive launches replacing an invalid ~/.claude.json with defaults (they now fail and explain how to restore it)

Behavior changes:

  • Claude Code no longer installs or updates the IDE extension when started in an IDE terminal. Use /ide from an outside terminal or your editor's extensions view
  • Background subagents move a shell command to the background after 3 minutes, so the prompt cache doesn't expire
  • deniedMcpServers URL entries also block Anthropic-provided servers and connectors whose upstream URL matches
  • Self-hosted runner log formats changed, so scripts matching retryable=true: need updating

Wrap-up

  • Sign-in expiry is visible, with a warning before it ends
  • The gateway gets assume_role for mantle upstreams
  • Config files are better protected against corruption and loss
  • Some behavior changes, such as no more automatic IDE extension installs

If you run Claude Code unattended or in shared environments, check these changes!
