VMware Tanzu Application Service for VMs [Windows] v2.12 Release Notes

This topic contains release notes for VMware Tanzu Application Service for VMs [Windows] v2.12.

Because VMware uses the Percona Distribution for MySQL, expect a time lag between Oracle releasing a MySQL patch and VMware releasing TAS for VMs [Windows] containing that patch.

How to Upgrade

The TAS for VMs [Windows] v2.12 tile is available with the release of TAS for VMs v2.12. To use the TAS for VMs [Windows] v2.12 tile, you must install Ops Manager v2.12 or later and VMware Tanzu Application Service for VMs (TAS for VMs) v2.12 or later.

New Features in TAS for VMs [Windows] v2.12

TAS for VMs [Windows] v2.12 includes the following major feature:

Gorouter Supports TLS v1.3

In TAS for VMs [Windows] v2.12, the Gorouter supports TLS v1.3. New installations of TAS for VMs use TLS v1.3 for the Gorouter by default. If you are upgrading to TAS for VMs v2.12, the Gorouter uses TLS v1.2 by default.

For more information, see Gorouter Supports TLS v1.3 in the TAS for VMs v2.12 release notes.

Breaking Changes

TAS for VMs [Windows] v2.12 includes the following breaking change:

(Beta) Gorouter Can Support TLS v1.3 Connections Only

TLS v1.3 is not compatible with some versions of Java. If you configure TAS for VMs [Windows] to support TLS v1.3 only, you might encounter errors with Java apps. For more information, see JSSE Client does not accept status_request extension in CertificateRequest messages for TLS 1.3 in the JDK Bug System.

The tile property that controls the TLS version in TAS for VMs [Windows] changes in TAS for VMs v2.12. You must update any stored configuration files to reflect the change.

Known Issues

See the following TAS for VMs [Windows] v2.12 known issue:

Upgrades Fail When the Stemcell Does Not Change

If you upgrade to a version of TAS for VMs [Windows] that uses the same stemcell, TAS for VMs [Windows] can fail to create containers, causing the deployment to fail. If there are stemcell changes or if the Microsoft base layer changes, this error is unlikely to occur.

For more information, see Failure to create containers when upgrading with shared Microsoft base image in the VMware Tanzu Knowledge Base.

Smoke Tests Fail when Isolation Segment in Foundation

The Smoke Test errand runs extra, failing tests when TAS for VMs [Windows] is deployed with Isolation Segment. They are “Compute isolation disabled” and “Application Workflow Linux Applications”.

To work around this issue, disable Smoke Tests. For more information, see Windows Tile smoke-tests fails for isolation segment segments in the VMware Tanzu Knowledge Base.
