Windows-hosted install script v2.0.0.2

Released on 2/7/2025

This release only contains changes to the Windows-hosted installation scripts for Connected Cache. To take advantage of these changes, you need to redeploy your existing cache nodes using the updated installation script.

Improvements

  • Removes dependency on AMQP/MQTT ports: Cache nodes deployed using this updated installation script will no longer use AMQP (5671) or MQTT (8883) ports. This change simplifies the network configuration for cache nodes and reduces the number of ports that need to be opened in your network security group.
  • Improves cleanup during uninstall: Windows-hosted cache nodes will now remove port proxy rules when uninstalled using the uninstallmcconwsl.ps1 script. This change ensures that the host machine's WSL port-forwarding rules are cleaned up properly when uninstalling Connected Cache.
  • Changes install error codes from decimal to hex code: Install error codes for Windows-hosted cache nodes are now displayed in hex code format, improving error code readability.
  • Uses configured proxy to perform install: If a proxy was configured for the Windows-hosted cache node in Azure portal, the cache node uses the specified proxy during installation.

Public Preview Release

Released on 10/30/2024

For customers that installed earlier versions of Connected Cache, this release contains breaking changes that affect both Linux-hosted and Windows-hosted cache nodes. See the early preview documentation page for more details.
