Claude Release Notes

HIPAA configuration for your Claude organizations is now self-serve

You can now manage HIPAA readiness for your Claude organizations yourself. This applies to both Claude Enterprise and the Claude Platform (API). In each product, an eligible admin can review the Business Associate Agreement (BAA), download the implementation guide, and enable the HIPAA configuration in a single flow. For more information, refer to HIPAA-ready Enterprise plans and HIPAA readiness for Claude API.

Updated memory for Claude

Memory on Claude now works as a set of individual, categorized entries that Claude reads and updates during your conversations, replacing the previous daily memory summary. See Use Claude’s chat search and memory to build on previous context.

A new way to reflect with Claude

Your monthly recap is a new feature at Settings > Reflect that shows you the topics you spent time on, your most active day and peak hour, and observations about how you work with Claude. It's in beta on Free, Pro, and Max plans on the web and Claude Desktop, and requires memory to be on. Alongside it, Settings > Time and focus lets you set optional break reminders and quiet hours. For more information, refer to See your monthly recap and Set break reminders and quiet hours.

Claude Cowork on web and mobile

Claude Cowork is now available on web and mobile in addition to desktop. We are rolling this capability out over the next several weeks starting with the Max plan, with more plans to follow. Cowork runs your sessions remotely (in beta), so your sessions and files are saved to your Claude account and go where you go, on any device. Work continues when you close your laptop, and scheduled tasks run with no device online. Chat and Cowork also share one home now, with one place for your projects and artifacts across both. For more information, see Use Claude Cowork on web, desktop, and mobile.

Write tools for the Microsoft 365 connector

The Microsoft 365 connector now goes beyond search. With write tools enabled, Claude can draft, send, and organize email, manage calendar events, update mailbox settings, and create and update files in OneDrive and SharePoint. Read and search tools work as before, and Teams remains read-only. Before members can use write tools, a Microsoft Entra administrator needs to consent to the updated permission set and an admin needs to enable them for the organization. For more information, see Set up the Microsoft 365 connector and Connect to Microsoft 365.

Highlight the part you want changed, type the change, and Claude makes the edit right where you marked it. No switching apps, no re-describing paragraphs in chat. For more information, see Work with artifacts.
