concordium-cis2 4.0.0

Summary

Bump concordium-std to version 7 and internal restructuring.

concordium-std 6.2.0

Summary

This release adds helpers and makes the crate work with recent nightly versions.

Changes

• Add write_root helper function to write the root of the state trie. This is
  useful in migrations when upgrading smart contracts.
• Bump Rust edition to 2021.
• Remove the use of alloc_error_handler since the feature is no longer
  available in recent nightly builds of the compiler. This can increase the
  smart contract size slightly.
• Set minimum Rust version to 1.60.

concordium-std-derive 5.2.0

Summary

• Fix derive(SchemaType) macro so that it allows the concordium attribute.
• Bump Rust edition to 2021.

concordium-cis2 3.1.0

Summary

This is a minor release adding quality of life improvements.

Changes

• Derive PartialEq and Eq for the MetadataUrl from the CIS2 library.
• Update concordium-std dependency to 6.2.

Release concordium-std 6.1.1

This update contains only internal restructuring. As a result it bumps contracts-common dependency to 5.3.1

Release concordium-std 6.1.0

This is a minor release that exposes additional quality of life helpers, and some additional functionality that was only available in concordium-std until now.

There are some minor breaking API changes that should affect very few users. The changelog below lists them.

Changelog

• Add Display implementation for OwnedParameter and Parameter, which uses
  hex encoding.
• Replace From<Vec<u8>> instance for OwnedParameter/Parameter with a TryFrom,
  which ensures a valid length, and the unchecked method new_unchecked.
  • Migrate from From/Into: Use new_unchecked instead (if known to be
    valid length).
• Make inner field in OwnedParameter/Parameter private, but add a From
  implementation for getting the raw bytes.
  • Migrate from parameter.0: use parameter.into() instead (for both of the affected
    types).
• For ModuleReference, replace AsRef<[u8;32]> with AsRef<[u8]> and make
  inner bytes field public.
  • The change was necessary for internal reasons.
  • Migrate from module_reference.as_ref(): use &module_reference.bytes instead.
• Replace OwnedParameter::new with OwnedParameter::from_serial, which also
  ensures a valid length.
  • Migrate from new(x): Use from_serial(x).unwrap() (if known to be valid length).
• Add an empty method for both OwnedParameter and Parameter.
• Implement Default for Parameter.
• Add StateBuilder::new_state_container method which allows contract developers to use
  their own container types atop blockchain storage
• Move the type AccountBalance to concordium-contracts-common.

Release concordium-std 6.0.1

concordium-std 6.0.1 (2023-02-28)

Fix local testing using the crypto-primitives feature.

• #225

Release concordium-std 6.0.0

concordium-std 6.0.0 (2023-02-08)

• wee_alloc is no
  longer set as the allocator in concordium-std but can be enabled via the
  feature wee_alloc. The consequence is that unless std feature is
  enabled either wee_alloc must be enabled, or another global allocator
  must be set in the smart contract. In std builds, unless wee_alloc
  feature is used, the allocator provided by the Rust standard library is used.

• Add a new primitive get_random for generating random numbers in Wasm code testing; get_random can be used in tests only, not available for smart contracts on the chain.
• Fix a linking issue when compiling contracts to native code on Windows and OSX.
