4th Ed Liberation query

[Poor Yorek]

The initial release of Liberation engendered some difference of opinion vis-a-vis the maps and pieces.  Does anyone know what APL means by "4th Ed standard" for the re-release of the game beyond simply the rule-set and tables?  Are the counters to be of the stamped sort (like AaD) or ...?  Is the shading of the maps to be less dense or the same as the original printing?

Just curious in advance of the Wait-and-See  (by someone else) approach.
