The third version of DotA 6.73 was released a few minutes ago, after the first map that was released before Christmas, followed a few days later by the 6.73b that fixed a few bugs and removed the Santa Pudge skin.
Since the winter holidays are over, the Christmas and the holiday graphic elements have been removed from the new map. A few technical optimizations have been made but the map file still has around 7 – 8 megabytes.
Regarding the fixes, there are 14 fixes for the 6.73c map, some regarding heroes and some regarding the new items that were introduced in 6.73.

Most likely, this map will be the last 6.73 map. We will see if there will be another release for the Warcraft 3 map since DotA 2 will be released soon and the community might move there.
Have a nice winter all!
