This release adds support for Protocol 22 and maintains backwards compatibility for Protocol 21.

See also: #104

To maintain compatibility for Protocol 21 until Protocol 22 is released you have to consider following braking changes if you are using this version of the SDK:

Horizon:

  • The deprecated fields amount and numAccounts have been removed from AssetResponse
  • The deprecated fields validBefore and validAfter have been removed from TransactionResponse

Soroban:

  • The legacy field cost has been removed from SimulateTransactionResponse
  • The createdAt field from TransactionInfo is now a String. It was int before.

Other tips for migrating to Protocol 22:

  • Soroban: The field pagingToken from EventInfo will not be filled any more starting with Protocol 22. Instead, the new field cursor in GetEventsResponse will be filled starting with Protocol 22.
  • Soroban: The new field txHash in GetTransactionResponse and TransactionInfo will be filled starting with Protocol 22.
  • Soroban: You can use the new CreateContractWithConstructorHostFunction class to create contracts that have a constructor.
