WIP: Changelog

(last update: 2016/03/16 17:04)

IMPORTANT: With Docker 1.11, a docker installation is now made of 4 binaries (docker, containerd, containerd-shim and runc). If you have scripts relying on docker being a single static binaries, please make sure to update them. Interaction with the daemon stay the same otherwise, the usage of the other binaries should be transparent.

Distribution

• Fix a panic that occurred when pulling an images with 0 layers (#21222)
• Fix a panic that could occur on error while pushing to a registry with a misconfigured token service (#21212)
• docker login will no longer prompt for an email (#20565)
• Docker will now fallback to registry V1 if no basic auth credentials are available (#20241)
• docker login now handles token using the implementation found in docker/distribution (#20832)
• Docker will now try to resume layer download where it left timeout after a network error/timeout (#19840)

Client

• docker ps no longer show exported port for stopped containers (#19483)

• docker ps now supports displaying the list of volumes mounted inside a container (#20017)
• docker info now also report Docker's root directory location (#19986)

Volumes

• Output of docker volume ls is now sorted by volume name (#20389)

• Docker will now return a 204 (i.e http.StatusNoContent) code when it successfully deleted a network (#20977)
• The devmapper driver learn the dm.min_free_space option. If the mapped device free space reaches the passed value, new device creation will be prohibited. (#20786)
• Docker can now prevent processes in container to gain new privileges via the --security-opt=no-new-privileges flag (#20727)

• docker update learned how to change a container restart policy (#19116)
• docker inspect now also returns a new State field containing the container state in a human readable way (i.e. one of created, restarting, running, paused, exited or dead)(#18966)
• Docker learned to limit the number of active pids (i.e. processes) within the container via the pids-limit flags. NOTE: This require CGROUP_PIDS=y to be in the kernel configuration. (#18697)

Logging

• Docker syslog driver now uses the RFC-5424 format when emitting logs (#20121)

Security

• send, recv and x32 were added to the list of allowed syscalls and arch in the default seccomp profile (#19432)

Misc

• Experimental support for building docker.exe in a native Windows Docker installation (#18348)
