v2.1.6

June 22, 2023 circom 2.1.6

Extensions

• Improving tag propagation: array case.
• Handling new prime numbers: pallas, vesta, grumpkin
• Improving array access index computation in the code generated intermediate representation: using cheap addition and multiplication operations when possible.
• Updating the documentation.
• Added check on the name of the circom file when --C is used to avoid clashes with reserved names. When the file is called main.circom, fr.circom or calcwit.circom it is changed to main_c, fr_c and calcwit_c respectively.

Bugs

• Fixing a bug while parsing anonymous components.
• Fixing a problem in calls to anonymous components with signal names.
• Fixing a bug in wasm witness generation that happened when doing a call inside an array index.
• Executing the main method without inputs in wasm witness generation.
