Open Design Alliance (ODA) binary dependencies were updated to version 26.8, providing support of Revit 2026 and resolving multiple related bugs.

We upgraded our third-party library Assimp to 6.0.2. Assimp is used for importing 3DS, DAE, FBX and OBJ files as well as exporting to FBX, GLTF and OBJ.

## New Features

Improved Revit Metadata Handling

Revit metadata processing has been enhanced in the following areas:

- Duplicate metadata entries have been eliminated to prevent attribute redundancy.
- Empty metadata attributes are now better filtered when `m_bReadEmptyAttributes` is set to A3D_FALSE, resolving cases where blank values were previously displayed despite the setting.

Support of Revit Connector Points

Connector points associated with a Revit element are now imported as `A3DRiPointSet` entities when `m_bReadConstructionAndReferences` is set to A3D_TRUE. These `A3DRiPointSet` entities are imported alongside the `A3DRiRepresentationItem` corresponding to the associated element.”

Support of 3DXML markup linked items

3DXML markup linked items are now imported, see CATIA V6 / 3DExperience Reader for details.

## Documentation Changes

Our C API Reference is undergoing significant work to improve structure, navigation, and clarity. This release delivers the first part of those changes, with more revisions planned to further improve usability and readability.
