Blender now caches loose edges and loose vertices for meshes, making drawing large meshes in the viewport and other operations faster after some node setups.Copies can also be skipped when duplicating attributes with the Store Named Attribute and Capture Attribute nodes ( b54398c16c).Avoiding copies when converting geometry types can make the Instance on Points, Instances to Points, Points to Vertices and Mesh to Points nodes at least 10x faster ( e45ed69349). Generally copying geometry to change part of it is much faster, and overal memory usage can be significantly better as well (at least 25% in simple situations).Blender and geometry nodes make use of a new system to avoid copying large data chunks, called "implicit sharing" ( 7eee378ecc, dcb3b1c1f9).Confusing units have been removed on some inputs to the String to Curves node ( 4f08eeae9c).The legacy read-only "normal" attribute has been removed from the spreadsheet ( 300c673a64).A new Index of Nearest node gives index of the closest "non-self" element ( 15f9e42c4f, d8f4387ac9, 4346314351).Index of nearest sample file, CC-BY Sean Christofferson
