5.3.1

Bug fixes

• Fix for Babbage mints occasionally resulting in incorrect tx hash: #329

5.3.0

Conway breaking changes

These are breaking changes for Conway (which is not part of Cardano mainnet yet) to update CML to the latest Conway specs

• New Conway.cddl updates by @rooooooooob in #324

Bug fixes

• Babbage Mint handle duplicate format by @rooooooooob in #327

5.2.0

New features

• Replace the auto-generated plutus datum JSON format (generated from cddl-codegen) with a standardized format used by cardano-node (even when used from within other structures)
• Add preview, preprod, and sancho to the NetworkInfo utility type

Bug fixes

• Fix Byron block hashes
• Fix parsing of Byron-era Epoch Boundary Blocks
• Fix potential errors when deserialization enums (see dcSpark/cddl-codegen#217)
• Fix string formatting of ipv6 text
• Fix the standalone hash_transaction utility function to return the right result (the .hash() function on the TransactionBody itself always worked)

Structure changes

• (rust) TransactionMetadatum moved from cml_core::metadata to cml_chain::auxdata::metadata
• (rust) return type of TransactionBody::hash() change from [u8; 32] to TransactionHash struct

Breaking Changes

Renamed BigInt to BigInteger to avoid collisions with the built-in JS type called BigInt by @rooooooooob #302

New features

Bug fixes

• Update ugly JSON schemas for types with non-trivial JS serialization by @rooooooooob in #300

Full Changelog: 4.0.2...5.0.0

4.0.2

What's Changed

• Into bytes instance for const size array-based wrapper types. by @oskin1 in #288
• Lint fixes for new lints in cargo 1.75 by @rooooooooob in #293
• Base/Enterprise/PointerAddress WASM bindings by @rooooooooob in #291
• Missing crypto wasm api by @rooooooooob in #292
• Misc wasm bindings by @rooooooooob in #295

Full Changelog: 4.0.1...4.0.2

4.0.1

The new v4 of CML contains a lot more code generated using cddl-codegen

Major features

• New native rust interface! No more need to use an ugly WASM interface when writing a Rust-native library. You can find the crates for all our packages at the bottom of this post
• Conway era support! Conway is the next era of Cardano. Learn more about the specification changes here
• Fixed memory leaks! Previously when using CML with JS, you had to manually manage memory or you would get memory leakage. This is no longer necessary.

Minor features

• CIP25 and CIP36 support are now packaged as part of CML. This is enabled since these specifications have a CDDL specification (so we can easily codegen them) and thanks to our native Rust interface support, composing different specs like this becomes much easier in Rust
• New multi-era crate for projects that want more explicit multi-era support instead of just the latest version of Cardano (note: the library size for this package is larger)

Bug fixes

There are a few bug fixes that come with the new codegen tool as well as some manual patches to part of the code where cardano-node deviated from the specification temporarily.
