This changelog's gonna be a lot shorter than the one for GSSH2, as there's a lot less stuff:

• Individual levels for each donut/muffin have been added, with the objective being to obtain the specified donut/muffin as fast as possible.
• Each IL has its own nickname (i.e. "Mouse" for Assorted Donuts) for ease of identification.
• Showing the cursor is now required for WR runs in every category.
• Community wiki link has been added to the sidebar.
• Game has been added to the "Garfield" series.
• Background image has been changed.

As far as I know, this should cover all of the leaderboard changes so far. Let me know if I've missed anything (i.e. a typo in the category rules or an inaccurate mistime), and feel free to reply to this post with any comments, questions, or concerns.
