concordium_base 3.0.0

Summary

Add support for protocol 6 and Web3ID. This release is a major release that also removes some deprecated functionality

Changes

• Remove the constant MAX_ALLOWED_INVOKE_ENERGY since it was no longer
  relevant with the way the node currently handles the invoke API.
• Add ED25519_SIGNATURE_LENGTH constant for the size of an ed25519 signature.
• Add concordium_contracts_common::{Serial,Deserial} implementations to
  CredentialPublicKeys and AccountAccessStructure.
• Add sign_data and generate methods to AccountKeys to sign arbitrary
  data, and to generate a fresh set of keys.
• Add From<&AccountKeys> instance for AccountAccessStructure.
• Add verify_data_signature function to verify a signature with account keys
  on arbitrary data.
• Update notation of sigma protocols to better match the literature and the bluepaper.
• Move all sigma protocols to a common sigma-protocol crate.
• Move all range proof helper functions to range_proofs.
• Add a new module web3id that defines types related to Web3ID and implements
  proving and verification functions.
• Add a new module cis4_types that defines the interface types for CIS4
  compatible contracts.

concordium-wasm 3.0.0

Summary

Add support for protocol 6.

Changes

• validate_module is now parameterized by ValidationConfig which determines
  which Wasm features should be allowed. The currently supported configurable features are
  • allow access to globals (defined in the current module) in data and element
    initialization sections.
  • allow instructions defined in the sign extension operators
    Wasm proposal.
• instantiate and instantiate_with_metering's return type is changed from
  Artifact to InstantiatedModule which adds metadata on top of the artifact.

concordium-smart-contract-engine 3.0.0

Summary

Add support for protocol 6.

Changes

• Functions that process V1 smart contract modules
  (invoke_receive_*_from_source and invoke_init_*_from_source) are now
  parameterized by a ValidationConfig which determines which Wasm features are
  allowed.
• ReceiveParams is extended with support_account_signature_checks flag, that
  enables or disables two new operations that can be invoked. Querying account
  public keys and checking account signatures.
• InvokeFailure is extended with two new variants
  SignatureDataMalformed and SignatureCheckFailed that can be triggered as a
  result of checking a signature.

concordium_base 2.0.0

Summary

• Extend types UpdatePayload and UpdateType with variants introduced in protocol version 6.
• Implement Serial and Deserial for num::rational::Ratio<u64> and Duration.
• Introduce types for protocol version 6: Ratio, ChainParameterVersion2, GASRewardsCPV1, TimeoutParameters and FinalizationCommitteeParameters.
• Bump concordium-contracts-common to version 7.

concordium-wasm 2.0.0

Summary

Bump concordium-contracts-common to version 7.

concordium-smart-contract-engine 2.0.0

Summary

Bump concordium-contracts-common to version 7.

concordium_base 1.2.0

Summary

This release brings a number of improved APIs and a bug fix for serialization in update instructions.
The concordium-contracts-common dependency is bumped to version 6, and no longer has the sdk feature. Using derive macros from that crate means that use concordium_base::contracts_common as concordium_std must be added to the modules where the derive macros are used.

Changes

• Add helpers to extract policy from credentials.
• Add helpers to TransactionTime to construct future timestamps relative to
  current time, and from a unix timestamp.
• Add new_ helpers to cis2::TokenId to simplify the common case of token id
  construction from integral types.
• Add new sigma protocol VecComEq for linking a vector commitment with individual commitments.
• Add VecCommitmentKey for generating vector commitments.
• Fix a serialization bug for UpdatePayload. The serialization did not match
  that of the node for AddIdentityProvider and AddAnonymityRevoker payloads.

concordium-wasm 1.1.0

Summary

Bump concordium-contracts-common to version 6.

concordium-smart-contract-engine 1.2.0

Summary

• Bump concordium-contracts-common to version 6.

concordium base 1.1.1

This is a minor release that adds convenience functionality.

• Add Serialize instances to Proof and Statement types, and its constituent
  parts (AtomicProof and AtomicStatement).
• Deserial for BTreeMap and BTreeSet no longer requires Copy constraint.
