Welcome to another installment of the Platforms Update. A few notables to highlight:

• Ubuntu 26.04 has been released, and corresponding IRIS support is coming soon.
• IRIS 2026.2 will bring an end to support for Ubuntu 22.04 and Windows 10.
• Revised minimum CPU specifications are in effect for 2025.3+

For those newly acquainted with these communications, this update provides details about recent enhancements as well as anticipated changes based on current information; however, future projections remain uncertain and the content should not be interpreted as a definitive product roadmap.
