DotA 6.83e will never come out, 6.83d is the last version

DotA 6.83d was released on 10 June 2015, 3 years ago.

Icefrog and all the developing team have moved over to DotA 2, to have better control over the game mechanics, not be limited by the Warcraft 3 editor anymore.

And why not, to make profit from the game, since Warcraft DotA was a simple Warcraft 3 map.

Since then, the official getdota.com website has been abandoned, it still runs but it only displays the latest DotA map version, without anything else being there.

Some other developers have started to develop new maps, based on 6.83d, but the Warcraft DotA map fame has faded over time.

Very few still play this game that was insanely good at some point in time.

There are still servers and places where people can play the game, Eurobattle.net, Battle.net, Garena and so on.
