Status: It works well, but there are still a few details to improve/fix More details about the changes: - New dependency on Arabica and Libxml2 to parse the XML - Loading the old format is still supported for this release, but won't be supported anymore in the next one - Games are now only saved in the new format - In training mode, the player is now created externally, like in the other modes - Avoid using GameIO (the one from game/) whenever possible - Do not use a FILE* argument anymore when loading a game - Throw and catch exceptions correctly when a game cannot be loaded or saved - The non-regression tests now use a new method to print the game history
