Blender is a free and open-source 3D computer graphics software application for modeling, rendering, video editing, and developing animated movies, visual effects, 3D games, and physics simulations. Blender is written in C, C++, and Python, and allows the user to write custom extensions to Blender in any of those programming languages. (Wikipedia) 

• Simulation Nodes: Geometry Nodes now support simulations (e.g., particle, physics, procedural effects) via a “Simulation Zone” node setup. 
• Faster scene loading & performance boosts: Meshes, point clouds, and curves load much more quickly.
• Hardware-accelerated ray tracing on AMD & Intel GPUs: Cycles rendering now takes advantage of AMD/Intel ray tracing features (though some limitations / experimental support apply).
• Improved UV tools & packing: UV unwrapping and packing algorithms get upgrades — better handling of concave shapes, pinned islands, rotation options, and faster viewport display. 
• User interface tweaks: Better menus, hover highlights, improved “Open Recent” list, more flexibility in quick favourites, and more context awareness. 
• New transform orientation “Parent”: You can now use a transform orientation tied to an object’s parent (or bone), which can simplify workflows in rigging or hierarchical setups. 
• Grease Pencil & Animation tools improvements: Weight painting tools in Grease Pencil modes, updated IK solver behavior (less strict root origin requirements), and small quality of life updates.
