## 1.0 (2015-10-13)
|
|
|
|
### 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.
|
|
|
|
## 0.4 (2015-08-04)
|
|
|
|
### Scheduler
