This release contains a security fix for [CVE-2024-29018], a potential data exfiltration from 'internal' networks via authoritative DNS servers.
New
Add Subpath field to the VolumeOptions making it possible to mount a subpath of a volume. moby/moby#45687
Add volume-subpath support to the mount flag (--mount type=volume,...,volume-subpath=<subpath>). docker/cli#4331
Accept = separators and [ipv6] in compose files for docker stack deploy. docker/cli#4860
rootless: Add support for enabling host loopback by setting the DOCKERD_ROOTLESS_ROOTLESSKIT_DISABLE_HOST_LOOPBACK environment variable to false (defaults to true). This lets containers connect to the host by using IP address 10.0.2.2. moby/moby#47352
containerd image store: docker image ls no longer creates duplicates entries for multi-platform images. moby/moby#45967
[CVE-2024-29018]: Do not forward requests to external DNS servers for a container that is only connected to an 'internal' network. Previously, requests were forwarded if the host's DNS server was running on a loopback address, like systemd's 127.0.0.53. moby/moby#47589
Ensure that a generated MAC address is not restored when a container is restarted, but a configured MAC address is preserved. moby/moby#47233
