21.0.1-preview.2

Release notes

This is the second preview 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 protocol-related changes

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

Breaking changes

• storage().max_ttl() getter has been changed to exclude the current ledger and thus it now returns a value that is one less than before. This is a bug fix that makes extend_ttl(max_ttl()) work correctly for the temporary storage entries. It can be observed though in case if max_ttl() has been directly compared with a hardcoded value (for example, in tests).
