### Release notes

#### Core

This is the first Core release 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
- Soroban 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

#### Soroban Rust SDK

This is the first version of the Soroban SDK that supports protocol 21. It is marked as 'preview' because contracts built with SDK v21 will only be compatible with the networks upgraded to protocol 21. The API itself may be considered stable. Key changes:

- Support for secp256r1 signature verification
- Support for extending TTL of contract instance and code separate from each other
