What Changed This Week
Section titled “What Changed This Week”Updated weekly as part of newsletter research.
13 February 2026
Section titled “13 February 2026”Operator’s Toolkit launched. The knowledge base goes live with the full site structure: Getting Started, Workflows, By Role, Platform Reference, Community, Enterprise, and Reference sections. Content is being populated in phases — platform pages and core workflows first, with role guides and enterprise content following.
11 February 2026
Section titled “11 February 2026”Free plan expansion. Skills and connectors (directory access) now available on the Free plan. Free users can now access 50+ integrations from the Anthropic Connectors Directory and toggle skills for document creation and data analysis. Custom MCP server URLs still require a paid plan.
10 February 2026
Section titled “10 February 2026”Cowork launches on Windows. Full feature parity with macOS. Available on Windows x64 — arm64 is not supported. Cowork can now read files, browse the web, execute code, and run plugins on Windows machines. Source: Anthropic
5 February 2026
Section titled “5 February 2026”Opus 4.6 released. New flagship model with state-of-the-art performance on finance benchmarks. Context window: 200K tokens default, with 1M token context available in beta (requires tier 4 API access and a special header). The expanded context is useful for processing entire codebases or long regulatory documents.
30 January 2026
Section titled “30 January 2026”Knowledge-work plugins launched. Anthropic released 11 open-source plugins: Productivity, Finance, Legal, Sales, Marketing, Data, Product Management, Customer Support, Enterprise Search, Bio Research, and Plugin Create. All available at claude.com/plugins and on GitHub. This triggered significant reactions in software markets, as specialist SaaS companies faced direct competition from open-source alternatives.

Section titled “27 January 2026”MCP Apps update. Claude can now render interactive UI elements for Slack, Asana, Figma, Canva, Box, Hex, monday.com, Notion, Amplitude, and Clay directly in chat.

January 2026
Section titled “January 2026”Claude in Chrome launched. Browser extension for Chrome (only — not Edge or other Chromium browsers) with workflow recording, scheduled tasks, multi-tab management, and “ask before acting” safety mode.
