Claude Code v2.1.84: Windows PowerShell Preview, 30ms Faster Startup
Releasebot·medium signal
Released March 26, v2.1.84 introduces Windows PowerShell as an opt-in preview tool — the first native Windows shell support beyond WSL. Startup time improved ~30ms through caching optimizations. Additional changes include model detection overrides, channel plugin allowlists, and fixes across input handling, terminal rendering, voice, and background task handling. This represents Anthropic's first real move toward native Windows support after community pressure over 6 critical WSL2 bugs closed as 'not planned.'
