This is a list of the changes and improvements made by Blizzard Entertainment to Diablo I. For Battle.net play, the game requires the latest patch, which it will install automatically. These patches are incompatible with the Hellfire expansion, which only received one patch from Sierra Entertainment and left many major issues unchecked.
This patch is download only, not an automatic Battle.net update.
For current troubleshooting information see the included update.txt file in your Diablo I game folder.
