When closing this issue, please respond with at least the GitHub release that supports Protocol 20.

Protocol 20: Soroban

The next version of the Stellar network will feature a new smart contract platform called Soroban. Note that this version features only additive changes: existing operations, etc. have not changed. (Protocol 20 will be the same thing as "Preview 11," the latest release of Soroban to Stellar Futurenet.)

New XDR Schema

• Your SDK should support encoding and decoding the new XDR schemas. The network protocol will use the XDR schema defined here: stellar-xdr @ 9ac0264.
• There are three new operations. The former is for invoking contract actions, while the latter two are related to state expiration (see [Interacting with Soroban via Stellar](https://soroban.stellar.org/docs/fundamentals-and-concepts/invoking-contracts

Shaptic

With the introduction of Protocol 14 and specifically CAP-33, accounts can now be created without a starting balance (given a sponsor).

The CAP notes:

Operation Validity Changes
Any downstream system relying on the fact that CreateAccountOp is invalid if startingBalance = 0 will be affected.

This subtlety is easy to overlook, so please ensure that the SDK allows this updated constraint.

If this SDK validates the starting balance to prevent starting balances of zero, please update the SDK to allow it.
