Claude Updates: Sonnet 4.6 1M Context Beta, Cowork on Pro, Code Included in Team Plans

Anthropic / Claude Release Notes·low signal

Anthropic rolled out several March 2026 updates: Sonnet 4.6 now offers a 1M token context window in beta, Cowork (multi-agent workspace) expanded to Pro plan users on Claude Desktop macOS, and Claude Code access is now bundled with every Team plan standard seat. The Code bundling is the most actionable for team builders—it removes the friction of separate Code licensing and signals Anthropic is treating Code as a core product rather than a developer add-on.
