Keep a portable copy in your own R2

Eligible Workspaces can now keep a portable copy of their content in a Cloudflare R2 bucket they control.

What changed

• Connect Cloudflare and choose an account, bucket, and root folder.
• Copy Markdown and referenced Assets while Letter.md remains the collaboration source.
• Pause new writes without disconnecting the storage location.
• Check storage health and reconnect when authorization changes.
• Prevent silent location changes when existing content depends on the connection.

Custom R2 availability depends on the current plan and Workspace configuration.
