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.

3.1.0

What's Changed

• Datum and redeemer insertion order by @MicroProofs in #130

Full Changelog: 3.0.1...3.1.0

3.0.1

What's Changed

• feat: add reference inputs used lang to script hash calc by @joacohoyos in #127

Full Changelog: 3.0.0...3.0.1

3.0.0

Breaking Changes

• The tx redeemer builder is no longer required. You can skip the step entirely if your transaction doesn't need to add Plutus scripts

Features

• Inputs added via add_input can now reference scripts added in the reference inputs

Bug fixes

• Fixed ordering of withdrawal & input redeemers sometimes being incorrect

2.0.1

Bug Fixes

• Fixed JSON type for ByronAddress

2.0.0

New features

• Add Byron txout support by @SebastienGllmt in #117
• Allow unchecked tx redeemer builder by @SebastienGllmt in #118

Breaking changes

• Add support for communication datums in outputs. The breaking change should be fairly simple: just wrap the TransactionOutput type with a SingleOutputBuilderResult where needed.
• The tx redeemer builder no longer required temporary signers

1.0.2
