concordium-rust-sdk 4.3.0

Summary

This is a maintenance release that mainly updates dependencies.

Changes

• Bump MSRV to 1.73
• Update dependencies. In particular concordium-base and concordium-smart-contract-engine are bumped to version 5.

concordium-rust-sdk 4.2.0

Summary

This release adds more helper functionality for writing indexers, allowing the user to focus on just the data manipulations.

Due to changes in transitive dependencies the minimum supported rust version is bumped to 1.72.

Changes

• Add a ProcessorConfig struct dual to the TraverseConfig to help in writing
  indexers.
• Bump MSRV to 1.72

concordium-rust-sdk 4.1.1

Summary

Fix incorrect calculation of the micro_ccd_per_nrg helper.

concordium-rust-sdk 4.1.0

Summary

This release adds helpers to streamline deployment and initialization of smart contracts.

Changes

• Add ContractInitBuilder for more ergonomic initialization of new smart
  contract instances with automatic NRG cost estimation.
• Add ModuleDeployBuilder for more ergonomic deployment of contract modules
  with automatic dry run and validation.

concordium-rust-sdk 4.0.0

Summary

This is a major release that updates some of the core dependencies, removes the V1 API, and adds some more convenience features in particular for updating smart contracts.

The key dependencies that are likely to affect users are

• rand is updated from 0.7 to 0.8
• tonic is updated from 0.8 to 0.10

Detailed list of changes follows.

Changes

• Add a From<&AccountInfo> instance for AccountAccessStructure to ease verification of signatures using GetAccountInfo response.
• Add a get_finalized_block_item method to the Client to retrieve a finalized block item from the node.
• Remove the V1 API.
• Add Display implementation to BlockIdentifier.
• Add Display and FromStr implementations for AccountIdentifier.
• Rename find_first_finalized_block_no_later_than into
  find_first_finalized_block_no_earlier_than since that correctly reflects its
  semantics with respect to time and is much clearer.
• Make the Client::new method slightly more general by accepting a
  TryInto<Endpoint>. This allows passing URLs as strings directly.
• Add a new indexer module that provides boilerplate for robustly traversing
  the chain.
• Support protocol version 7.
• Support for smart contract debugging when running locally.
• Remove JSON serialization support of BlockSummary.
• Add an additional indexer to index all transaction outcomes and special events.
• Make the energy field of ContractContext optional since it is no longer
  required by the node.
• Add dry_run_update and dry_run_update_raw methods to the ContractClient
  to simulate smart contract updates. The return values of these can be used to
  immediately sign and send a transaction.
• Update rand dependency to 0.8.
• Update tonic to 0.10.

concordium-rust-sdk 3.2.0

Summary of changes

• The SDK now requires a rustc version at least 1.67 (Before it required version 1.66).
• Add a contract_update helper analogous to contract_init to extract an
  execution tree from a smart contract update transaction.
• Add a ccd_cost helper to ChainParameters to convert NRG cost to CCD.
• Add support for DryRun. Requires a node version at least 6.2.

concordium-rust-sdk 3.1.0

Summary

Add support for node version 6.1 API and a number of utility functions.

Changes

• Add a commission_rates field to CurrentPaydayBakerPoolStatus which yields the commission rates
  of the baker for the reward period. Requires a node version at least 6.1.
• Add support for GetWinningBakersEpoch. Requires a node version at least 6.1.
• Add Support for GetFirstBlockEpoch. Requires a node version at least 6.1.
• Add support for GetBakersRewardPeriod endpoint. Requires a node version at least 6.1.
• Add Support for GetBakerEarliestWinTime endpoint. Requires a node version at least 6.1.
• Add support for GetBlockCertificates. Requires a node version at least 6.1.
• Add make_update and make_update_raw methods to the ContractClient. They
  are like update and update_raw but instead of sending a transaction they
  only construct it and return it.
• Add make_register_credential, make_revoke_credential_as_issuer and
  make_revoke_credential_other to the CIS4 client. These are like the methods
  without the make_ prefix, except that they only construct the transaction,
  they do not send it.
• Add make_transfer and make_update_operator functions to the CIS2 client.
  These are like the methods without the make_, except that they only
  construct the transaction.
• Update minimum supported rust version to 1.66.

concordium-rust-sdk 3.0.1

Summary

Update concordium-base dependency to at least 3.0.1.

concordium-rust-sdk 3.0.0

Summary

This major release adds support for protocol 6, and deprecates the V1 GRPC client.
The V1 client will be removed in a release in the beginning of November.

Changes

• The SDK requires node version 6 or later.
• Support relative and absolute block height as the block identifier in block queries.
• Add field protocol_version to BlockInfo which is the protocol version of the queried block.
• Extend enum PendingUpdateEffect with variants for protocol version 6.
• Introduce ChainParametersV2 struct for protocol version 6.
• Introduce generic gas_reward in RewardParametersSkeleton for supporting different versions of GASRewards.
• Add find_account_creation helper to find a block where the account was
  created.
• Deprecate find_earliest_finalized and replace it with
  find_at_lowest_height that avoids an extra call to the node. This is making
  use of the new API.
• Re-export http::Scheme from http crate since it is often needed when
  configuring endpoints.
• Add a new ContractClient that supports operations on smart contract
  instances such as queries and updates.
• Add a Cis4Contract for interacting with Cis4 contracts.
• Add a new web3id module that contains types and functionality for
  construcing Web3ID credentials and verifying Web3ID proofs.
• Deprecate the client for V1 of the node's API.

concordium-rust-sdk 2.4.0

Summary

This is a minor release which updates the dependencies.
In particular using derive macros for smart contracts serialization now requires an extra import. See changes for details.

Changes

• Re-export concordium_base to enable use of concordium_base_derive
  serialization macros.
• Bump minimum supported rust version to 1.64.
• When using derive(Serial,Deserial) macros from the smart_contracts modules
  concordium_std must be made available, for example as
  use concordium_rust_sdk::smart_contracts::common as concordium_std
