What is new in Altium Designer 25

Detecting Changes within Net Classes, Diff Pairs, and Diff Pair Classes

Changes within net classes, differential pairs, and differential pair classes (new/removed elements) imported from directives before are now detected, with an indication of any inconsistencies requiring synchronization (between schematics and Constraint Manager) with an orange bar at the left of the corresponding object name.

Enhanced Placement of Die Pads on Overlapped 3D Bodies

Die pads are now bound, by height, to the 3D body they are placed on instead of the highest 3D body in the die pad location. This allows die pads to remain on the surface of the correct 3D body when there are multiple 3D bodies in the same location (for example, when the PCB is covered by an enclosure).
