Enhancements
============

**Apple Silicon support.** Native support for Apple Silicon is being introduced in this release. Binary packages for Apple platforms now contain universal binaries that run natively on both Apple Silicon (ARM) and Intel-based (x64) Mac computers for your convenience. Minimum requirements for development on macOS raised to 10.14 and XCode 12. Refer to this link for more information on porting your macOS application to Apple Silicon: `Apple Developer Documentation <https://developer.apple.com/documentation/apple-silicon/porting-your-macos-apps-to-apple-silicon>`_.

**Better sample models.** Improved the selection of sample models provided for Android ARCore sandbox.

**Hardware-accelerated text.** Hardware-accelerated text preserves highlight alignment fidelity and visual clarity of the font as you zoom in and out on text to improve appearance at any zoom level.


Functional Changes
==================

.. only:: not spatial

	**HOOPS Exchange.** |HPSTHEN| now works with HOOPS Exchange 2021 SP2.

	**HOOPS Publish.** |HPSTHEN| now works with HOOPS Publish 2021 SP2.
	
	**|HCTHEN|.** |HPSTHEN| now works with |HCTHEN| 2021 SP2.

**Windows compatibility.** |HPSTHEN| on Windows 32-bit platforms is now considered deprecated and will be removed in the future. The minimum supported Windows OS is now Windows 10, 64-bit.

**ARCore.** |HPSTHEN| now works with ARCore v1.20. This version of ARCore is used in the Android AR Sandbox and adds support for the ARCore lighting API that can be used to automatically set up distant lights and add shadows, thereby improving overall appearance. Does not include support for light intensity or HDR.

**Freetype.** Upgraded Freetype 2.10.4 to address critical vulernabilities and exposures.

**OpenGL1 removed.** The OpenGL1 driver is no longer available. Developers may use OpenGL2 in normal contexts, or OpenGL2_Mesa, which is available starting in |HPSTHEN| 2020 SP1 and 3DF 26.00 when software-only rendering is preferred or required.


Known Issues
============

**Non-aligned highlights.** Highlights will potentially be unaligned with geometry in cases where static model and two different geometry highlights are used, and the two highlights target geometries having different transforms. This issue is scheduled to be resolved in the next release.
