Claude Code 2.1.111 adds /ultrareview and PowerShell

Version 2.1.111 is a significant step toward making Claude Code a viable replacement for human peer reviews while finally addressing Windows developer friction.

• –/ultrareview employs a fleet of remote agents for deep logic analysis, moving beyond surface-level syntax checks to identify architectural flaws.
• –Native PowerShell support eliminates the need for Git Bash or WSL workarounds, which has been a major adoption barrier for Windows-based enterprise teams.
• –The 1-hour prompt cache TTL option solves the "token bleeding" problem for developers who work in bursts, significantly reducing input token costs for long-running sessions.
• –The new Opus 4.7 xhigh model effort level provides a "goldilocks" balance between reasoning depth and latency for complex refactors.
• –New UX features like /less-permission-prompts and typo correction make the CLI feel more like a collaborator and less like a fragile interface.
