That doesn't sound good....
I have looked through the changelog:
1. A synchronization in the MapMaker class was removed. Do you use more 
than 1 thread?
2. The procedure how the list of relevant tags that are read from the 
OSM file is created was changed a bit. Maybe this introduced a bug so 
that some things are missing now. Can you do a quick check, if you are 
missing some POIs or highways or polygons in the r1753 map?
3. The procedure how the mulitpolygon processing removes tags from the 
original ways was changed. Either this introduced or fixed a bug. ?!? 
Yeah, it is possible that the old algorithm missed some tag removals on 
lines and polygons so that the number of objects was too large in the maps.

It would be great if we have a tool that reads the IMG-file and creates 
a statistic of how many objects are contained in the file. Do we have 
that already?! I think I remember a thread about that but I cannot find it.
