  • Fixed the Ephemeral Disk Provisioning for Azure enabling compatibility of PASW’s ephemeral disk functionality with OpsMgr on Azure.

Known Issues

  • For Google Cloud Platform (GCP) users, a bug in PASW causes outbound connections from applications deployed on PASW with this stemcell version to fail. The resolution will come in patch versions of PASW v2.1, v2.2 and v2.3.

1803.2

Release Date: October 1, 2018

Features

  • Includes ephemeral disk support. This enables you to configure the size of your Windows cells in the PASW tile. For more information, see the Configure Tile Resources section in Installing and Configuring PAS for Windows. This also allows you to reduce your root disk to a minimum of 30 GB.
  • Intended for use with the September 2018 Microsoft Security Updates.

Bug Fix

  • Previously, the os_version argument was mandatory during the Invoke-Sysprep step. The OS is now detected by default, and the os_version argument is optional.

1803.1

Release Date: September 24, 2018

Features

  • This is the first 1803 stemcell.
  • Intended for use with the August 2018 Microsoft Security Updates.
  • Includes an important Microsoft Security Update that provides protections against a new speculative execution side-channel vulnerability known as L1 Terminal Fault (L1TF). For more information, see Windows Support.
  • Compatible with the latest stable OpenSSH version, OpenSSH_for_Windows_v7.7.2.0p1.

Known Issue

  • The v1803.1 Windows stemcell does not support ephemeral disks. Support for ephemeral disks is expected in v1803.2. This enables you to configure the size of your Windows cells in the PAS for Windows tile. For more information, see Step 4: Configure Tile Resources of Installing and Configuring PAS for Windows.
