 ## Future Work
 
 The current focus is to gather as much feedback as possible while in the alpha phase. The main focuses of Noir are _safety_ and _developer experience_. If you find a feature that does not seem to be in line with these goals, please open an issue!
 
-Concretely the following items are on the road map:
-
-- General code sanitization and documentation (ongoing effort)
-- Prover and Verifier Key logic. (Prover and Verifier pre-process per compile)
-- Fallback mechanism for backend unsupported opcodes
-- Visibility modifiers
-- Signed integers
-- Backend integration: (Bulletproofs)
-- Recursion
-- Big integers
