web-sdk v4.0.0

Breaking changes

• Updated blockInfo so that the bakerId field is optional, since it will be undefined for genesis blocks.
• waitForTransactionFinalization now returns a BlockItemSummaryInBlock
• Added missing version return type in getModuleSchema. It now returns an object containing the schema source and version.

Added

• Helpers for calculating energy cost for a transaction and microCCD cost from energy cost:
  • getEnergyCost
  • getExchangeRate
  • convertEnergyToMicroCcd
• Utility functions for extracting information from BlockItemSummary:
  • isInitContractSummary
  • isUpdateContractSummary
  • isTransferLikeSummary
  • isRejectTransaction
  • isSuccessTransaction
  • getTransactionRejectReason
  • getReceiverAccount
  • affectedContracts
  • affectedAccounts
• Utility functions for extracting information from BlockSpecialEvent:
  • specialEventAffectedAccounts
• Helper methods on GRPCClient for chain traversal:
  • getFinalizedBlocksFrom
  • findEarliestFinalized
  • findInstanceCreation
  • findFirstFinalizedBlockNoLaterThan
• Extended HdWallet with support for verifiable credential key derivation.

web-sdk v3.4.1

Fix the gRPCv2 client's helper function waitForFinalization, so it doesn't use setImmediate, which is not supported in the browser.

web-sdk v3.4.0

• Added a general function for deserializing smart contract values deserializeTypeValue.
• signMessage and verifyMessageSignature can now handle the message being a buffer/Uint8Array instead of only a utf8 string.
• Updated dependencies to fix incorrect serialization of negative numbers for smart contract values.
• serializeTypeValue now reports an error when called with invalid data, such as a receive function with missing schema, or a schema that cannot be parsed.

node-sdk v6.3.0

• serializeTypeValue now reports an error when called with invalid data, such as a receive function with missing schema, or a schema that cannot be parsed.

web-sdk v3.3.1

• Added a client for version 2 of the Concordium gRPC API to communicate with a Concordium node.
  • including helper function waitForTransactionFinalization that returns a promise that resolves when the transaction finalizes.
• Added a createConcordiumClient function to create the gRPC v2 client.
• Support for the configureBaker transaction type.
• getInitContractParameterSchema, getUpdateContractParameterSchema, serializeInitContractParameters and serializeUpdateContractParameters now report an error when called with invalid data, such as a receive function with missing schema, or a schema that cannot be parsed.
