starkware-libs/cairo v2.6.0-rc.0

on GitHub

This is the Cairo version associated with Starknet 0.13.1. Contracts written with 2.6.0 are not declarable on Starknet until the upgrade.

Major Updates

• Added support for gas coupons.
  • Gas coupons are a way to pay for calling a function, in a different place then the actual function call.
  • Allows support for recursive destructs (as we can hold such a coupon for the recursive destruct call in the recursive object).
  • Only available with experimental flags.
• Support for const simple value, as well as wrapping structs and enums of these in Sierra.

New Feautres

• Better manual gas handling - if gas is handled manually - gas withdrawal is not automatically added. #4880
• Added if-let expression support.
• Added support for underscore pattern in match on tuples. #4996
• Add cmp::minmax function by @delaaxe in #4981

Optimizations

• Improved performance for ecdsa. #4985
