Breaking changes
The Azure PowerShell (Az) module will be updated from 14.6.0 to 15.6.1 on all runner images. Az 14.x is no longer supported by Microsoft - only the latest version receives security fixes and support. See the Az PowerShell support lifecycle.
This is a major version upgrade (14 → 15) and may contain breaking changes. Please review the Az 15.x migration guide and release notes for details.

Target date
This change will be rolled out beginning June 1, 2026 and will complete by June 7, 2026.
The motivation for the changes
Az PowerShell 14.x is no longer supported by Microsoft. Unlike other products, the Az PowerShell module does not have LTS versions - only the latest release is supported. Running an unsupported version poses security risks and means that support tickets filed with Microsoft will not be addressed until the module is updated.
The current version on most runner images is 14.6.0, which was released in January 2026. Since then, multiple security patches and improvements have been shipped in the 15.x line.
Possible impact
Workflows that use Az PowerShell cmdlets may be affected by breaking changes between Az 14.x and Az 15.x. Key areas include:
- Cmdlet parameter changes and removals
- Output type changes for some cmdlets
- Deprecated cmdlets removed
If your workflows rely on specific Az 14.x behavior, please review the migration guide and test your scripts accordingly.
To pin a specific Az version in your workflow, you can use:
Install-Module -Name Az -RequiredVersion 14.6.0 -Force -AllowClobber
Platforms affected
Runner images affected
Mitigation ways
If you need to continue using Az 14.x, you can install it explicitly in your workflow:
Install-Module -Name Az -RequiredVersion 14.6.0 -Force -AllowClobber
Alternatively, update your scripts to be compatible with Az 15.x by following the migration guide.
