Node 1.35.4 supports the use of SECP256K1 elliptic curves via new Plutus primitives at protocol version 8. It also includes some CLI improvements, including changing the default ledger era to Babbage for transaction commands.
Please note that this version contains breaking changes, as listed below:
Breaking Changes
- With this version, all transactions are created in the Babbage ledger era format if
--<ledger-era>-erais not passed as an option.
Known Issues
-
Shelley ledger era Tx body in CDDL format is not supported by some CLI commands (#3688)
-
Please see here for other known issues. None of these is considered to be a blocker.
They will be addressed in future releases.
