Technology Update
=================

.. note::

   The minimum required C++ standard has been raised from **C++11** to **C++14**.
   
   * All build toolchains must now enable at least -std=c++14 (or /std:c++14 on MSVC).
   * Downstream integrators compiling custom modules against our headers must adapt their build configurations accordingly.
   
   Minimum Linux requirements have also been raised. Please refer to the :doc:`Supported Platforms documentation </overview/supported-platforms>` for details.

* **Official NPM Repository Launch:** Developers can now directly download and integrate the HOOPS Web Viewer client and related packages via NPM.

* **Open Source UI Library:** Our UI component library is now open-sourced and available from its `Github repository <https://github.com/techsoft3d/hoops-visualize-web-components>`__, supporting transparency in our UI development.

* **html2canvas Update:** Dependency updated from html2canvas 0.5.0-beta-4 to html2canvas-pro 1.5.8.


Deprecated Features and Functions
=================================

* Deprecation of shipped Node.js; now considered a server-side requirement. Removal of Node.js from the package is scheduled for release 2026.1.0.
* Deprecation of legacy server wrappers.
* Deprecation of the old UI.
* Deprecation of HTML templates associated with the old UI.
* Deprecation of over 43 material-related functions. These have been replaced by the new `IMaterial` interface. Full removal of these functions is planned for release 2026.1.0.

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

* The snapshot feature is now working within the new demo and when using web components.
* General availability of the new UI libraries.
* General availability of new HTML templates aligned with the new UI libraries.
* General availability of `IMaterial` interface for improved material management in the WebViewer.
* Added experimental API for setting and getting draw modes per node. Information pertaining to this experimental API can be found :doc:`here </prog_guide/viewing/scene_attributes/draw-modes>` under the section **Per Node Draw Mode Override**. This API isn't definitive and may change in future releases.

Package Changes
===============

The following packages are now available via NPM:

.. csv-table::
   :header: "Package", "Description"

   "@ts3d-hoops/web-viewer-components", "Library for Advanced UI elements"
   "@ts3d-hoops/ui-kit", "Library for simple UI elements"
   "@ts3d-hoops/web-viewer", "Multi files version of HOOPS Visualize Web WebViewer"
   "@ts3d-hoops/common", "Dependency for HOOPS Visualize Web WebViewer @ts3d-hoops/web-viewer"
   "@ts3d-hoops/streamcache", "Dependency for HOOPS Visualize Web WebViewer @ts3d-hoops/web-viewer"
   "@ts3d-hoops/sc-engine", "Dependency for HOOPS Visualize Web WebViewer @ts3d-hoops/web-viewer"
   "@ts3d-hoops/web-viewer-monolith", "Monolithic version of HOOPS Visualize Web WebViewer"

Additionally, two dedicated React wrappers have been published to support React-based applications:

.. csv-table::
   :header: "Package", "Description"

   "@ts3d-hoops/web-viewer-components-react", "React wrapper for @ts3d-hoops/web-viewer-components"
   "@ts3d-hoops/ui-kit-react", "React wrapper for @ts3d-hoops/ui-kit"

These packages are actively used in our demo application and are fully supported for production use.
