xcircuit has been updated to 3.7.44. Version 3.7 has a modified selection mechanism that considers both points and segments of elements as well as entire elements. This allows the "edit" function to work as a stretch function to many elements at once.
Also added linewidth invariance on objects. Object instances (such as circuit symbols) can be made linewidth-invariant, such that an instance of the object can be scaled without changing the linewidth. This allows some circuit symbols to be resized relative to others on the same schematic without a discontinuity in wire width at the pins.
A number of other useful additions including:
