  - https://docs.microsoft.com/azure/batch/nodes-and-pools
  - https://docs.microsoft.com/azure/batch/batch-spot-vms

11.0.0 (2021-07-30)

Features

Add ability to assign user-assigned managed identities to CloudPool. These identities will be made available on each node in the pool, and can be used to access various resources.
Added identity_reference property to the following models to support accessing resources via managed identity:
- AzureBlobFileSystemConfiguration
- OutputFileBlobContainerDestination
- ContainerRegistry
- ResourceFile
- UploadBatchServiceLogsConfiguration
Added new compute_node_extension operations to BatchServiceClient for getting/listing VM extensions on a node
Added new extensions property to VirtualMachineConfiguration on CloudPool to specify virtual machine extensions for nodes
Added the ability to specify availability zones using a new property node_placement_configuration on VirtualMachineConfiguration
Added new os_disk property to VirtualMachineConfiguration, which contains settings for the operating system disk of the Virtual Machine.
- The placement property on DiffDiskSettings specifies the ephemeral disk placement for operating system disks for all VMs in the pool. Setting it to "CacheDisk" will store the ephemeral OS disk on the VM cache.
Added max_parallel_tasks property on CloudJob to control the maximum allowed tasks per job (defaults to -1, meaning unlimited).
Added virtual_machine_info property on ComputeNode which contains information about the current state of the virtual machine, including the exact version of the marketplace image the VM is using.

10.0.0 (2020-09-01)

Features

[Breaking] Replaced property maxTasksPerNode with taskSlotsPerNode on the pool. Using this property tasks in a job can consume a dynamic amount of slots allowing for more fine-grained control over resource consumption.
[Breaking] Changed the response type of GetTaskCounts to return TaskCountsResult, which is a complex object containing the previous TaskCounts object and a new TaskSlotCounts object providing similar information in the context of slots being used.
Added property requiredSlots to the task allowing user to specify how many slots on a node it should take up.

9.0.0 (2020-03-24)

Features

Added ability to encrypt ComputeNode disk drives using the new disk_encryption_configuration property of VirtualMachineConfiguration.
[Breaking] The virtual_machine_id property of ImageReference can now only refer to a Shared Image Gallery image.
[Breaking] Pools can now be provisioned without a public IP using the new public_ip_address_configuration property of NetworkConfiguration.
- The public_ips property of NetworkConfiguration has moved in to public_ip_address_configuration as well. This property can only be specified if ip_provisioning_type is UserManaged.

REST API version

This version of the Batch .NET client library targets version 2020-03-01.11.0 of the Azure Batch REST API.

8.0.0 (2019-8-5)

Using REST API version 2019-08-01.10.0.
- Added ability to specify a collection of public IPs on NetworkConfiguration via the new public_ips property. This guarantees nodes in the Pool will have an IP from the list user provided IPs.
- Added ability to mount remote file-systems on each node of a pool via the mount_configuration property on CloudPool.
- Shared Image Gallery images can now be specified on the virtual_machine_image_id property of ImageReference by referencing the image via its ARM ID.
- Breaking When not specified, the default value for wait_for_success on StartTask is now True (was False).
- Breaking When not specified, the default value for scope on AutoUserSpecification is now always Pool (was Task on Windows nodes, Pool on Linux nodes).

7.0.0 (2019-6-11)

Using REST API version 2019-06-01.9.0.
- Breaking Replaced AccountOperations.list_node_agent_skus with AccountOperations.list_supported_images. list_supported_images contains all of the same information originally available in list_node_agent_skus but in a clearer format. New non-verified images are also now returned. Additional information about capabilities and batch_support_end_of_life is accessible on the ImageInformation object returned by list_supported_images.
- Now support network security rules blocking network access to a CloudPool based on the source port of the traffic. This is done via the source_port_ranges property on network_security_group_rules.
- When running a container, Batch now supports executing the task in the container working directory or in the Batch task working directory. This is controlled by the working_directory property on TaskContainerSettings.

6.0.1 (2019-2-26)

Fix bug in TaskOperations.add_collection methods exception handling

6.0.0 (2018-12-14)

Using REST API version 2018-12-01.8.0.
- Breaking Removed support for the upgrade_os API on CloudServiceConfiguration pools.
  - Removed PoolOperations.upgrade_os API.
  - Renamed target_os_version to os_version and removed current_os_version on CloudServiceConfiguration.
  - Removed upgrading state from PoolState enum.
- Breaking Removed data_egress_gi_b and data_ingress_gi_b from PoolUsageMetrics. These properties are no longer supported.
- Breaking ResourceFile improvements
  - Added the ability specify an entire Azure Storage container in ResourceFile. There are now three supported modes for ResourceFile:
    - http_url creates a ResourceFile pointing to a single HTTP URL.
    - storage_container_url creates a ResourceFile pointing to the blobs under an Azure Blob Storage container.
    - auto_storage_container_name creates a ResourceFile pointing to the blobs under an Azure Blob Storage container in the Batch registered auto-storage account.
  - URLs provided to ResourceFile via the http_url property can now be any HTTP URL. Previously, these had to be an Azure Blob Storage URL.
  - The blobs under the Azure Blob Storage container can be filtered by blob_prefix property.
- Breaking Removed os_disk property from VirtualMachineConfiguration. This property is no longer supported.
- Pools which set the dynamic_vnet_assignment_scope on NetworkConfiguration to be DynamicVNetAssignmentScope.job can now dynamically assign a Virtual Network to each node the job's tasks run on. The specific Virtual Network to join the nodes to is specified in the new network_configuration property on CloudJob and JobSpecification.
  - Note: This feature is in public preview. It is disabled for all Batch accounts except for those which have contacted us and requested to be in the pilot.
- The maximum lifetime of a task is now 180 days (previously it was 7).
- Added support on Windows pools for creating users with a specific login mode (either batch or interactive) via WindowsUserConfiguration.login_mode.
- The default task retention time for all tasks is now 7 days, previously it was infinite.
Breaking Renamed the base_url parameter to batch_url on BatchServiceClient class, and it is required now.

Update operation TaskOperations.add_collection with the following added functionality:
- Retry server side errors.
- Automatically chunk lists of more than 100 tasks to multiple requests.
- If tasks are too large to be submitted in chunks of 100, reduces number of tasks per request.
- Add a parameter to specify number of threads to use when submitting tasks.

5.0.0 (2018-08-24)

Using REST API version 2018-08-01.7.0.
- Added node_agent_info in ComputeNode to return the node agent information
- Breaking Removed the validation_status property from TaskCounts.
- Breaking The default caching type for DataDisk and OSDisk is now read_write instead of none.
BatchServiceClient can be used as a context manager to keep the underlying HTTP session open for performance.

Breaking The following operations signatures are changed:
- Operation PoolOperations.enable_auto_scale
- Operation TaskOperations.update
- Operation ComputeNodeOperations.reimage
- Operation ComputeNodeOperations.disable_scheduling
- Operation ComputeNodeOperations.reboot
- Operation JobOperations.terminate
Enum types now use the "str" mixin (class AzureEnum(str, Enum)) to improve the behavior when unrecognized enum values are encountered.

Fix regression on method enable_auto_scale.

4.1.0 (2018-03-07)

Using REST API version 2018-03-01.6.1.
Added the ability to query pool node counts by state, via the new list_pool_node_counts method.
Added the ability to upload Azure Batch node agent logs from a particular node, via the upload_batch_service_logs method.
- This is intended for use in debugging by Microsoft support when there are problems on a node.

4.0.0 (2017-09-25)

Using REST API version 2017-09-01.6.0.
Added the ability to get a discount on Windows VM pricing if you have on-premises licenses for the OS SKUs you are deploying, via license_type on VirtualMachineConfiguration.
Added support for attaching empty data drives to VirtualMachineConfiguration based pools, via the new data_disks attribute on VirtualMachineConfiguration.
Breaking Custom images must now be deployed using a reference to an ARM Image, instead of pointing to .vhd files in blobs directly.
- The new virtual_machine_image_id property on ImageReference contains the reference to the ARM Image, and OSDisk.image_uris no longer exists.
- Because of this, image_reference is now a required attribute of VirtualMachineConfiguration.
Breaking Multi-instance tasks (created using MultiInstanceSettings) must now specify a coordination_commandLine, and number_of_instances is now optional and defaults to 1.
Added support for tasks run using Docker containers. To run a task using a Docker container you must specify a container_configuration on the VirtualMachineConfiguration for a pool, and then add container_settings on the Task.

Added a new operation job.get_task_counts to retrieve the number of tasks in each state.
Added suuport for inbound endpoint configuration on a pool - there is a new pool_endpoint_configuration attribute on NetworkConfiguration.
This property is only supported on pools that use virtual_machine_configuration.
A ComputeNode now also has an endpoint_configuration attribute with the details of the applied endpoint configuration for that node.

3.0.0 (2017-05-10)

Added support for the new low-priority node type; AddPoolParameter and PoolSpecification now have an additional property target_low_priority_nodes.
target_dedicated and current_dedicated on CloudPool, AddPoolParameter and PoolSpecification have been renamed to target_dedicated_nodes and current_dedicated_nodes.
resize_error on CloudPool is now a collection called resize_errors.
Added a new is_dedicated property on ComputeNode, which is false for low-priority nodes.
Added a new allow_low_priority_node property to JobManagerTask, which if true allows the JobManagerTask to run on a low-priority compute node.
PoolResizeParameter now takes two optional parameters, target_dedicated_nodes and target_low_priority_nodes, instead of one required parameter target_dedicated.
At least one of these two parameters must be specified.
Added support for uploading task output files to persistent storage, via the OutputFiles property on CloudTask and JobManagerTask.
Added support for specifying actions to take based on a task's output file upload status, via the file_upload_error property on ExitConditions.
Added support for determining if a task was a success or a failure via the new result property on all task execution information objects.
Renamed scheduling_error on all task execution information objects to failure_information. TaskFailureInformation replaces TaskSchedulingError and is returned any
time there is a task failure. This includes all previous scheduling error cases, as well as nonzero task exit codes, and file upload failures from the new output files feature.
Renamed SchedulingErrorCategory enum to ErrorCategory.
Renamed scheduling_error on ExitConditions to pre_processing_error to more clearly clarify when the error took place in the task life-cycle.
Added support for provisioning application licenses to your pool, via a new application_licenses property on PoolAddParameter, CloudPool and PoolSpecification.
Please note that this feature is in gated public preview, and you must request access to it via a support ticket.

- file.get_node_file_properties_from_task -> file.get_properties_from_task
- file.get_node_file_properties_from_compute_node -> file.get_properties_from_compute_node
The attribute 'file_name' in relation to file operations has been renamed to 'file_path'.
Change in naming convention for enum values to use underscores: e.g. StartTaskState.waitingforstarttask -> StartTaskState.waiting_for_start_task.
Support for running tasks under a predefined or automatic user account. This includes tasks, job manager tasks, job preparation and release tasks and pool start tasks. This feature replaces the previous 'run_elevated' option on a task.
