Release notes

This is the first release of Soroban environment supporting protocol 21.

New features in protocol 21

• Secp256r1 support in Soroban host: https://github.com/stellar/stellar-protocol/blob/master/core/cap-0051.md
• Host function for extending TTL of contract instance and code separately: https://github.com/stellar/stellar-protocol/blob/master/core/cap-0053.md
• Use refined cost model for VM instantiation in order to reduce the VM instantiation metered costs: https://github.com/stellar/stellar-protocol/blob/master/core/cap-0054.md
• Intra-transaction VM module caching for the further Soroban cost reduction: https://github.com/stellar/stellar-protocol/blob/master/core/cap-0055.md, https://github.com/stellar/stellar-protocol/blob/master/core/cap-0056.md
