# 3DF 30.20

Note

Upcoming Change to Product Package Names
To improve clarity and consistency, HOOPS will adopt a unified naming scheme across all products. New package names will include product, version, platform, architecture, and compiler details. This change will take effect no earlier than the 30.30 release in September 2025.

## Technology Update

### Platform Changes

- HOOPS Visualize 3DF is now compatible with Qt 6 on Windows platform toolchains 14.2 and 14.3. Compatibility with Qt 6 on Linux and MacOS platforms is currently targeted for 3DF 30.30.
- Support for Linux ARM platforms is available as a Beta release. It is not recommended to use this release in a production environment. Any errors encountered specific to the ARM architecture will only be considered for resolution in a future release.
- Support for all Microsoft Windows 10 editions is scheduled to end in October 2025 in coordination with Microsoft’s scheduled end of life policy.
- Support for OpenGL on macOS is deprecated and will no longer be supported starting in January 2026. Partners will have to migrate to Metal in order to maintain support for Apple devices in the future.
