 # Bug fixes, improvements
 - MagicDNS now uses DNS-over-HTTPS when querying popular upstream resolvers, so DNS queries aren't sent in the clear over the Internet.
-- automatically try the IPv6 address of common global DNS servers if IPv4 fails.
 - Portmapper now supports UPnP mappings as another way to traverse NAT.
 - Support serverless container operation with AWS App Runner, Azure App Services, AWS Lightsail Containers, and other AWS container services built atop AWS Fargate infrastructure.
 - Fix saving of preferences when bringing tailscale from down to up. (also in 1.10.2)
