* `POST /containers/create` now includes a `Consistency` field to specify the consistency level for each `Mount`, with possible values `default`, `consistent`, `cached`, or `delegated`.
|
||||
* `GET /containers/create` now takes a `DeviceCgroupRules` field in `HostConfig` allowing to set custom device cgroup rules for the created container.
|
||||
* Optional query parameter `verbose` for `GET /networks/(id or name)` will now list all services with all the tasks, including the non-local tasks on the given network.
|
||||
* `GET /containers/(id or name)/attach/ws` now returns WebSocket in binary frame format for API version >= v1.28, and returns WebSocket in text frame format for API version< v1.28, for the purpose of backward-compatibility.
