v11

Improvements:

• Reduce storage account queries
• Fix retry issue in asynchronous operations.

Fixes:

• Use LUN and host device id as the disk identifier
  • Compatible Stemcell Versions: v3181 or later
  • Stemcell v3232.5 or later is recommended with CPI v11. You may hit the issue #135 if you still use an older stemcell than v3232.5
• Use a data disk as the persistent ephemeral disk
  • The VM size should not be Standard_A0 if you want to use persistent data disks
  • The CPU cores of VM should be more than 1 if you plan to resize the persistent data disks in future
  • The premium storage is recommended for better performance
  • You can see more information about the 'Max data disks' and 'Max disk IOPS & bandwidth' of Azure Linux VMs here
• Fix an issue in calculating the sleep interval when copying blobs

Dev:

• Updated Ruby to 2.2.4
• Removed several unnecessary gem dependencies

v10

New Features:

• Add AzureChinaCloud support

Improvements:

• Auto retry when an internal error occurs in asynchronous operations
• Reduce retry interval to improve performance

v9

New Features:

• Allow specifying security_groups for a VM via resource pool's cloud_properties
  • Strongly recommded to be specified when using public IPs
• Allow specifying default_security_group as a global configuration

v8

Improvements:

• Assign public IPs directly to VMs
  • Previously public IPs were assigned by adding a LB to the VM
• Retry around DNS resolution errors
  • Typically shown as SocketError: Hostname not known

Dev:

• Set open_timeout explicitly for HTTP requests
