Claude Code March 2026: Voice Mode, 64k Output Tokens, 1M Context Default for Max/Team/Enterprise
Claude Code Docs·high signal
Claude Code's March 2026 updates include voice mode via /voice with push-to-talk (hold spacebar), /effort command with an 'ultrathink' keyword for maximum reasoning effort, and Opus 4.6 output token limit raised to 64k default with 128k upper bound. The 1M context window is now default for Max, Team, and Enterprise plans; MCP servers can now request structured input mid-task via interactive forms or browser URLs without interrupting workflow. These are significant daily-driver quality-of-life improvements for heavy Claude Code users.
