v1.0.0

Noteworthy changes from 0.4.0

Scheduler:

• Swarm is now pulling Images in parallel after the scheduling decision has been made, which mitigates the error happening occasionally with Docker pulls blocking the entire scheduler.

General stability:

• The Node refresh loop process has been improved and does not yield to a panic when removing an Engine and trying to refresh the state at the same time.
• The refresh loop has been randomized to better handle huge scale scenarios (> 1000 nodes) where a refresh burst could occur and make the Manager unstable/fail.
• General improvements and fixes for the Mesos experimental backend for swarm.

Integration with libnetwork / Support for overlay networking:

• It is now possible to use the new networking features with Swarm through the network sub-system. Commands like docker network create, docker network attach and docker network ls are now available through swarm.

Integration with Docker Volume Plugins:

• You can now use the docker volume plugin subsystem available with docker volume.

Leader Election:

• You can now specify the --replication-ttl flag to control how long it takes for Replicas to be notified of the Primary failure and take over the lead.

TLS:

• This is now possible to use TLS with discovery for consul and etcd using the new --discovery-opt flag.
