Common

Security update: Mitigate a high-severity vulnerability by upgrading all products.

Change Type	Description
Security	As part of our ongoing commitment to product security and stability, we've implemented several improvements in this release: Mitigated high-severity CVE-2025-27598 in App Designer, Data Stream Designer, and AI Designer by upgrading SixLabors.ImageSharp from 3.1.5 to 3.1.7. Expanded the automated test coverage for Recommendations.
Security	Ubuntu 20.04 LTS will reach its end of standard support on 31 May 2025. Running the XMPro Stream Host on an unsupported operating system may expose your environment to security vulnerabilities and compliance risks. XMPro strongly recommends using the Docker-based Stream Host as the preferred method for all new installations and upgrades, and is supported on a wide range of modern platforms, including newer Ubuntu LTS releases.
Fix	A change in v4.4.18 caused SSO integration with Azure AD to behave differently for guest accounts, and users are requested to link them again. This has been resolved without requiring any changes to the guest username.
Documentation	The installation content for AWS and Windows Server 2022 (previously known as On-Prem" have been updated. When upgrading XMPro instances that use AI Notebooks installed via ARM deployments, you may encounter known issues with the automated upgrade process. The Azure installation content has been updated to include this workaround: Manual Deploying Notebooks on AKS - Overview.

App Designer

Change Type	Description
Documentation	The Metablock documentation was updated to clarify that only plain text values are supported for encrypted Server Variables value mapping.

Stream Host

Change Type	Description
Enhancement	Configuration Simplification Gateway ID and Gateway Name are now optional parameters. If not provided, the system will auto-generate a GUID for Gateway ID and use the format [Image-Version]-[Gateway Id] for Gateway Name, reducing required configuration steps.
Enhancement	Unified Container Repository All Stream Host images are now consolidated under the single xmpro.azurecr.io/stream-host repository. The previous separate xmprocontrib.azurecr.io repository has been eliminated for simplified image management.
Enhancement	Streamlined Image Variants Reduced image complexity from 4+ variants to 3 clear options with version-specific tagging that includes base OS and Python version, making it easier to choose the right container image for your deployment: 4.4.19-bookworm-slim (Debian) 4.4.19-bookworm-slim-python3.12 (Debian with Python) 4.4.19-alpine3.21 (Alpine)
Enhancement	Simplified Deployment Experience Minimum required environment variables reduced from 6 to 3 for basic setup. Basic deployment examples no longer require separate .env files, making initial configuration more straightforward.
Documentation	Improved Documentation and Examples Added hardware requirements sizing guidelines, shell-specific examples for PowerShell and Bash/Terminal, improved Docker Compose YAML structure with better commenting, and Git Bash compatibility support with MSYS_NO_PATHCONV=1 for Windows users, providing clearer setup guidance and reducing deployment troubleshooting time.

NuGet Packages
