New features

Tentative support for the Alonzo hardfork. As the hardfork has not happened yet, we cannot guarantee there will not be other last minute changes requires (it's up to IOHK, not us)

Important notes

• The TransactionBuilder utility struct does not offer support for any Alonzo features at the moment (actively being worked on)
• Transactions that don't use any Alonzo-specific functionality (smart contracts) are backwards compatible with Mary (current Cardano version)
• If you want to know how Alonzo works at the binary-specification level, consider watching this video that explains all the changes
