## Platform Changes

- |HPSTHEN| support has now been extended to include Linux on ARM64 (ARMv8-A). The minimum supported OS is RHEL 8 with Devtoolset 9. See our Supported Platforms Supported Platforms page for details.
- Support for RealDWG 2023 and 2025 starts with this release. Note the compiler requirements differ for each specific RealDWG version.
- 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.

## Features and Enhancements

- |HPSTHEN| now reports animation ticks, so it’s possible to implement a playback slider
- |HPSTHEN| can now display a text string cursor. The cursor can be moved to any position in a text string to insert or delete a character. This is an implementation of the existing text cursor from HOOPS 3DF.

## Functional Changes

- We have deactivated the Sprocket DWG in debug mode only because of a limitation from Autodesk DWG causing instability. Sprocket DWG is still available in release mode.
