^v6.6.1 Fixed "babbage" being reported as the block era for Conway blocks. (🐛 @AndrewWestberg)
^v6.6.0 Fix upgradability of Alonzo/Babbage transactions into Conway transactions. Before, Babbage transaction submitted for evaluation that spent Plutus V3 Scripts while using a Babbage serialization format would failed to upgrade into Conway transactions due to incompatibility at the binary level. The translation has been fixed, except for truly incompatible transactions (e.g. those containing MIR or duplicate certificates). (🐞 @vladimirvolek)
