Release notes for 1.4.0
1.4.0
  • Update cardano-serialization-lib to 14.1.2
  • Update cardano-message-signing-browser to 1.1.0
  • Support Conway transactions

1.3.0
  • Make UTxO override affect the balance
    Previously, the utxo list override only affected the getUtxos() call and not the
    getBalance() call.
    The UI only allows overriding the ADA value of the balance.
    With this change, the users will be able to use the same UI to override the token balance returned by getBalance().

1.2.0
  • Fix SundaeSwap hanging (#17)

SundaeSwap and many other dApps seem to be not happy if the API object
returned by wallet.enable() is not a plain object.

They could be doing something like Object.keys(api) which trips up due to
the presence of internal methods present in the dev wallet, or they
could be doing something like apiCopy = {...api}.

Not sure of the exact mechanism, but returning a plain object seems to
fix this.

1.1.0
  • Fix bugs in the Ogmios/Kupo backend:
  • UTxO index was incorrect.
  • Tokens were missing from the UTxO list.
  • Allow specifying custom endpoint for blockfrost.
  • Auto activate newly created accounts and backends if there's none active.
  • Inject the wallet before any script in the page is run.
  • Add seperators in UTxO list, wallets list and network backends list.
