@@ -33,3 +33,5 @@ Once you install the app, you can connect to anybody:
 1. Create your local chat profile - it is not shared with SimpleX servers. It is local to your devices, and it will be shared with your contacts only when you connect.
 2. To make a private connection, you need to create a one-time connection link or a QR code via the app. You can show the QR code to your contact in person or via a video call - this is the most secure way to create a connection - or you can share the link via any other channel. Only one user can connect via this link.
 3. Once another user scans the QR code or opens the app via the link the connection will be created and you can send end-to-end encrypted messages privately, without anybody knowing you are connected.

+# SimpleX Chat v2.1 - better conversation privacy
+
+**Published:** May 24, 2022
+
+## New in version 2.1 - clearing conversations without deleting contacts
+
+In this version you can irreversibly delete individual messages after they were deleted by a sender, and also completely clear the conversation.
+
+The only way to do it before this version was by deleting the contact, now you can keep the connection when you clear the conversation.
