This is the Cairo version associated with Starknet 0.13.2. Contracts written with 2.7.0 are not declarable on Starknet until the upgrade.

Major Updates

  • Trait and Impl items (types, constants, and impls):
    • Example usage for types would be Iterator::Item.
    • Example usage for constants would be NumericBounds::MAX (does not exist just yet).
    • Example usage for impls would be IntoIterator::Iterator.
  • SHA256 support.
  • Modulus Circuit Support - allows for efficient calculations of large modular computations without branches.
  • Storage path and pointer concepts.
    • Instead of only being able to access storage in contract and component context - StoragePath StoragePointer are supplied, allowing for functions out of this scope to access these, as well as allowing for recursive definitions of maps and other structures.
  • Added support for access to members of types implementing the Deref and DerefMut traits.

New Features

  • Fixed sized array support for .span() allowing accessing it efficiently as if it was an array.
  • Add flag to enable gas to cairo-test. #5288
