A new feature in Teams: Share contact information in chat. And one feature change: Web pages will open in browser

Microsoft Teams makes it easier to share contact information for easier collaboration. Within a chat it will now be possible to use the @ mention to bring up a contact card you can send and share with others within your organization. Helping your colleagues connect with one another just got easier.

This is associated with the Roadmap ID: 375627

Another change in Teams, is how the "website tab" inside a channel behaves. In the coming weeks and months, webpages will no longer be displayed in the tab, but rather open a seperate web browser tab (your default). This is to better align with emerging best practices in web security and privacy while also improving the reliability of websites.
