It is a rather substantial collection of bug fixes, performance improvements, tidy-ups, speed-ups etc to the original Scratch developed by the MIT team. Project files read and saved are fully compatible with the original system.

I use a Cog/Spur system and make no representation about how well it might work on a non-spur or non-Cog system - I just don???t know and don???t really care.
