Recrafted is a reimplementation of CC: Tweaked's CraftOS, intended to be cleaner and easier than CraftOS.

Key changes:

• No. More. CCPL!!
• All previously global APIs (with the exception of the standard Lua ones) have been removed.
• Non-standard os API functions are now in the rc table, e.g. os.sleep becomes rc.sleep or os.pullEvent becomes rc.pullEvent.
• Native support for proper thread management (parallel implementation builds on this)
• Multishell works even on standard computers, and is navigable with keyboard shortcuts!

See the Recrafted website for more details.
