Claude Code v2.1.215: Login-Expiry Warnings, Mode Badges, and VS Code Remote Control

TL;DR: Claude Code v2.1.215 adds login-expiry warnings, clearer mode-status badges, and a VS Code remote control setting — plus streaming and startup memory improvements.

Released July 19 (after the earlier v2.1.214 security batch), v2.1.215 brings three quality-of-life changes: login-expiry warnings tell you when your OAuth token has expired instead of letting sessions stall silently — a common friction point for teams running long-running background sessions; clearer agent-status and manual-mode UI badges make the active permission mode visible at a glance in the status bar; and a new VS Code remote control setting for remote-development workflows. The release also trims startup memory, improves streaming responsiveness, and fixes edge cases in macOS, Windows, worktree, and daemon handling.

Why it matters: Silent auth failures that look like hangs are one of the top sources of Claude Code confusion in shared environments — this warning turns an invisible failure into an actionable prompt.
