• VM new functionality added as part of the environment interface 1.2:
  • Fully managed functionality for elliptic curves (no allocator);
  • Fully managed cryptographic functions (no allocator);
  • More efficient printing of big ints and hex;
  • Functionality available by adding the ei-1-2 flag to contracts.
• BigFloat functionality. Since the functionality is not yet deployed on mainnet, use flag big-float to use.
• Major refactoring of the call value mechanism:
  • TokenIdentifier now only refers to ESDT, for mixed EGLD+ESDT we have EgldOrEsdtTokenIdentifier.
  • EsdtTokenPayment now only refers to ESDT, for mixed EGLD+ESDT we have EgldOrEsdtTokenPayment.
  • Compact version for multi-transfer: let [payment_a, payment_b, payment_c] = self.call_value().multi_esdt();.
  • Explicit single_esdt vs. single_fungible_esdt vs. egld_or_single_esdt vs. egld_or_single_fungible_esdt.
  • Payment arguments are still supported, although discouraged. They always assume the EGLD+ESDT scenario.
• ManagedOption provides some minor optimization for specific use-cases. Mostly for use in the framework.
• Cleanup in the callback mechanism and in the SendApi.
• SparseArray implementation.
• UniqueIdMapper - efficient storage mapper for holding unique values.
• The ABI also contains events.
• New standard module: StakingModule.
