It might be a couple of things:
- A newer, slightly more pliable breed of ABS is being used. It is more readily
available, holds it's color better, is available in more colors (rather than
having to add a lake [dye] to the ABS beads), and weighs slightly less than the
older ABS. It's molding temperatures and pressures are slightly less as well.
- Some of the molds have been retooled slightly. This is because some of the
parts that required compound molds can now be achieved in simpler molds, due to
the newer ABS. With these new molds, edge fillets can more accurately be used
without as much flash oozing out. As a result, many of the pieces seem to
connect more readily, if not a bit more "sloppily". Compare a new half beam's
cross axle connection to an old one. The old one will have very sharp edges on
both sides. The new one will have one slightly sharp edge side and one slightly
rounded side.
