A lot has changed, it is probably a good idea to look at NEWS and at the top of the README file. The points most likely to cause confusion are:
- Klotski has gone.
- Lines has been renamed Five or More
- Background setting in gnometris is no longer done through the properties dialog, it is done by dragging an image onto the playing area. The standard back-grounds are no longer distributed.
- There are probably some interesting issues to do with aisleriot and its new window-resizing code. Bug reports and suggestions are welcome. Also, the selection of card themes is rather limited right now.
