# Changelog

## concordium-cis2 6.2.0 (2024-09-19)

- Bump MSRV to 1.72
- Add `FromStr` implementations for `TokenId` types.
- Add a `serde` feature that derives `serde::Serialize` and `serde::Deserialize` for `TokenId` types, `TokenAmount` types, `OnReceivingCis2DataParams<T, A, D>`, `OnReceivingCis2Params<T, A>`, `AdditionalData`, and `Receiver`.
- Fix `SchemaType` implementation of `OnReceivingCis2DataParams<T, A, D>` so that it matches `Serial` and `Deserial` implementations.

## concordium-cis2 6.1.0 (2024-02-22)

- Support version 10 of concordium-std.

## concordium-cis2 6.0.0 (2024-01-22)

- Add specific parameter type `OnReceivingCis2DataParams<T, A, D>` for a contract function which receives CIS2 tokens with a specific type D for the AdditionalData.
- Add `Deserial` trait for `OnReceivingCis2DataParams<T, A, D>`.
- Add `Serial` trait for `OnReceivingCis2DataParams<T, A, D>`.
- Update `concordium-std` version to `9`.

## concordium-cis2 5.1.0 (2023-10-18)
