Sorry about that, there were some changes in the code but your old saves will work fine in this version. Just a disclaimer for players that might have problems:
Possibly Important Information on save files:
There could be a possibility old saves are not there anymore.
That's because the directory of where the save files are stored have been changed.
To fix that, you'll have to go C:\Users\"yourpcname"\AppData\Roaming\renpy or just search for %appdata% or the RenPy save folder. Copy your saves from the old save map to the new one. Sorry for the inconvenience, it's a one time thing.
Gallery:
The second part is that the gallery might not show your character name correctly.
That's because the gallery does not know what you named your character in the previous versions. To fix that, just start a new game, input a character name, save and check the gallery again and it will display your name correctly.
