What

A new environment variable lets you point artifact syncing at a different host, alongside the existing asset, live and viewer base URLs. Unset by default, so nothing changes unless you set it.

Details
  • Added to the recognised artifact environment variables.
  • The file relay that moves artifact files now fetches each file by its own subpath instead of requesting the bare version root.
