In addition to bug fixes and general identifier name changes for Hive assets, this version of Radiator now incorporates hive-ruby as the primary basis for interacting with the blockchain.
So why use Radiator at all when you can just use the hive-ruby gem directly? Well, that's because Radiator can do failover as well as access the Hive Engine API.
Not only that, Radiator can also still work with Steem (and Steem Engine), if you're into that sort of thing.
To update your applications:
bundle update
hive-ruby and steem-rubyattr_reader for Radiator::Type::Amount #28get_transaction during recover_transactions_on_error
