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.

Warning: Windows stemcells v2019.44 and later include a version of tar that is incompatible with winfs2019-release v2.33.1 and earlier. For more information, see Windows Stemcell v2019.44 is Incompatible with winfs2019-release v2.33.1 and Earlier below.

Before you install the tile, review the Windows Stemcell Compatibility Matrix.

v2.12.9

Release Date: 06/23/2022

Warning: Upcoming breaking changes! In future patches, no sooner than July 1st 2022, some components will become more strict about the protocols used in TLS communications, causing integrations with systems using older, insecure protocols to fail. Specifically, components using the Go programming language will be updated to Go 1.18, and will no longer support TLS 1.0 and 1.1 connections or certificates with a SHA-1 checksum. This is most likely to affect connections with external databases. However, the pre-existing configuration for "TLS versions supported by the Gorouter" will still work. This change may not arrive all at once, as Go is used in systems throughout TAS for VMs. There will be a VMware Knowledge Base article about this change published prior to the changes rolling out. These changes will be clearly designated in the release notes of the versions they ship in; a version of this warning will appear on all patch versions until we are confident no systems remain to be updated.

v2.12.8

Release Date: 06/09/2022

Warning: Breaking change. This version contains Diego 2.64.0, which bumps to Go 1.18. Go 1.18 no longer supports TLS 1.0 and 1.1 connections or certificates with a SHA-1 checksum. This is most likely to affect connections with external databases. We stated earlier that we wouldn't bump to Go 1.18 until July 1, 2022. This TAS for VMs release with Diego 2.64.0 breaks that promise. We apologize. We are rolling back to Diego 2.62.0. If you already successfully deployed to this TAS for VMs release with Diego 2.64.0, then you are safe to continue using it.

How to Upgrade

The TAS for VMs [Windows] v2.12 tile is available with the release of VMware Tanzu Application Service for VMs (TAS for VMs) v2.12. To use the TAS for VMs [Windows] v2.12 tile, you must install VMware Tanzu Operations Manager v2.10 or later and 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 VMware Tanzu Application Service for VMs v2.12 Release Notes.

Breaking Changes

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

(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.

Diego Drops App Logs That Exceed the App Log Rate Limit

As of TAS for VMs [Windows] v2.12.12, if you have configured an app log rate limit that measures app log rates in lines per second, Diego immediately drops app logs that exceed the app log rate limit.

In TAS for VMs [Windows] v2.12.11 and earlier, Diego buffers and releases approximately 5 MB to 10 MB of app logs that exceed the app log rate limit. This behavior has changed in TAS for VMs [Windows] v2.12.12 because Diego has been upgraded to a newer version.

If this change in behavior causes parts of your deployment to fail, VMware recommends that you either modify any automated scripts that rely on app log output or increase the app log rate limit.

For more information about app log rate limits, see App Log Rate Limiting.

Optional TAS for VMs [Windows] 3.0 compatible syslog option

TAS for VMs [Windows] 3.0 includes changes to syslog forwarding. These changes include:

  • Changes in syslog format to better match other tiles.
  • Allows securely forwarding logs with tls enabled.
  • Includes bosh logs to match other tiles and to aid in debugging and auditing the system.

These changes will only be enabled if you turn off compatibility_mode in the system logging window of the settings.

The formatting changes are detailed as follows:

  • The priority is changed from kernel/debug(7) to user/info(14).
  • The app name is changed from Microsoft-Windows-Security-Auditing to event_logger.
  • The process number is changed from a numerical process ID to rs2.
  • Logs contain structured data for instance and deployment details.
  • The event log JSON string includes additional fields.
  • In the event log JSON string, field names are written in camel case.
  • In the event log JSON string, fields may appear in a different order.

The following example shows the previous log format:

Known Issues

TAS for VMs [Windows] v2.12 includes the following known issues:

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 is Deployed

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.

Windows Stemcell v2019.44 is Incompatible with winfs2019-release v2.33.1 and Earlier

Windows stemcells v2019.44 and later include a newer version of tar that is incompatible with winfs2019-release v2.33.1 and earlier. TAS for VMs [Windows] deployments that use Windows stemcells v2019.44 and later cannot untar winfs2019-release v2.33.1 and earlier. Compatible Windows stemcells for winfs2019-release v2.33.1 and earlier include v2019.0 through v2019.43.

Windows Stemcells Without Git Installed Cause VSC Stamping Failures

If Git is not installed either on your Windows stemcell or in the PATH environment variable for your Windows stemcell when you deploy TAS for VMs [Windows] v2.12.12, you may see the following error:

Stderr: 	Use -buildvcs=false to disable VCS stamping.

This occurs because some TAS for VMs [Windows] v2.12.12 use Go v1.18, which embeds VSC information in binaries. As a result, releases that contain .git files require that Git is installed either on your Windows stemcell or in the PATH for your Windows stemcell. If you do not have Git installed in either location and have not set the buildvcs property to false, Go v1.18 fails to build the release.

TAS for VMs [Windows] v2.12.12 contains windows2019fs-release. Because windows2019fs-release contains .git files, deployments of TAS for VMs [Windows] v2.12.12 using Windows stemcells that do not have Git installed on them or in their PATH fail with the VSC stamping error above.
