CMake: removed the old command line definition GTK_USE_AUIBOOK and replace it with GTK_USE_NATIVEBOOK (default: 0)
Git plugin: moved file context menu to the new event wxEVT_CONTEXT_MENU_FILE. This will allow in the future to place the git file context menu for any tree
and not only the workspace view
