|HPSTHEN| 2025.4.0
##################

.. attention::
  | **For Windows users only:**
  | |HPSNOW| 2025.4.0 has been superseded by |HPSNOW| `2025.4.1 <https://docs.techsoft3d.com/hps/2025.4.1/index.html>`__ due to a digital signature expiration. Non-Windows platforms are unaffected and need not update.
  
.. 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 2025.7.0 release in mid-September 2025.
