Matrix Games has a patch for Panzer Corps to update the strategy game to version 1.11, paving the way for the new Panzer Corps Grand Campaign ’42-43 West DLC, which is now also available for the game. The patch is available on this page (it's also mirrored on AtomicGamer and Gamer's Hell), and the DLC is offered here. This is the description of the new grand campaign:

Set during WWII on the Western Front, Germany is now facing the Western Allies as they engage in campaigns of hit and run raids to gather intelligence and probe their costal defences for weaknesses. Take command of a newly-formed task force to repel these commando raids and to prepare for the eventual return of the Western Allies to Europe! Fight at Dieppe, Syracuse, repel the Salerno landings, and more to prove yourself as the thorn in the Allies’ side.

The DLC contains 14 all-new scenarios that utilize and expand on the new features implemented with the release of Panzer Corps: Afrika Korps, creating a truly new and unique campaign. Players can use their core forces that completed previous campaigns as it gains experience and new equipment, or alternatively use a preset core force and play each of the campaigns on its own or jump in at any year.
