HOOPS Exchange 2026.6.0
#######################


Technology Updates
==================

Format Updates
--------------

================== ==================== 
*Format*           *Updated Version*
================== ====================
Creo               13.4.0.0
JT                 10.11
================== ====================

See :doc:`/start/supported-formats` for the list of all supported formats.

Platform Changes
----------------

The Linux x86_64 binaries now require at most the GLIBCXX_3.4.25 symbol from libstdc++ (down from GLIBCXX_3.4.28).
This improves compatibility with older Linux distributions, allowing HOOPS Exchange to run out of the box on systems such as RHEL 8 without requiring any additional workarounds.


New Features
============

New Format
----------

================== ==================== 
*Format*           *Version*
================== ====================
QIF                3.0
================== ====================

* **QIF Reader Support**: With the ongoing development of the QIF format reader, HOOPS Exchange 2026.6.0 now provides a beta version of the QIF reader.
  As a beta release, the QIF Reader has some limitations. For a detailed list of current limitations, please refer to the :doc:`/start/format/qif_reader` documentation page.

Feature Requests
----------------

* **Improved Creo Assembly Fidelity**: Assemblies using Creo's Pro/PROGRAM feature to suppress components now render accurately, matching the original design intent.
  Programmatically driven component states are faithfully preserved during import and visualization.
* **SolidWorks Construction Geometry Support**: HOOPS Exchange now fully extracts SolidWorks "For construction" geometry elements, including lines and circles.


API Changes
