Claude Code v2.1.206 Released with 20+ Fixes and Improved Background Agent Upgrade

Claude Code v2.1.206 introduces directory path suggestions for /cd, matching /add-dir behavior; adds /doctor check to suggest trimming CLAUDE.md content that Claude can infer from codebase; /commit-push-pr now automatically allows pushing to configured push remote besides origin. Gateway /login supports Anthropic-run public gateway endpoints; EnterWorktree asks for confirmation before entering git worktrees outside .claude/worktrees/. The key improvement is that background Agents now auto-upgrade in the background after Claude Code updates, eliminating slow stale session upgrades when attaching. Additionally, over 20 issues are fixed, including misleading expired login errors, ignored MCP server configuration timeouts, unresponsive keyboard input, OAuth MCP server token refresh failures, and incorrect /model selector pricing display. /code-review quality improved on claude-opus-4-8, Agent view status column no longer truncated to 64 characters, Ctrl+X permanently removes completed sessions. For developers using Claude Code, these fixes reduce daily friction and errors; background Agent auto-upgrade makes long-running tasks smoother without manual intervention.
