Changes
* A new control for viewing documents with 3D content was added. It allows basic pinch/zoom/selection actions with touch and mouse and currently supports .obj, .3ds and .stl formats, without textures. It is now the default document viewer for UBK documents with .obj extension, both in DetailsPage as well as DocumentsPage.
* The in-app PDF viewer now re-renders documents after zooming to provide better readability.
* UBIK now actively clears out cached properties to reduce its memory footprint. See [[Fast_Startup_(Client)#Technical_background|Fast Startup - Technical background]] for more details.* Further reduced the memory consumption for local content. (More properties are only loaded on demand.)
