Note

Significant performance improvements (mostly on CPU) across all boards mostly due to the integration of Plutus V3.

1.9.0

compiler compatiblity
>= v1.0.28-alpha

Added

• A new module aiken/pairs to work with associative lists (a.k.a. Pairs). (@KtorZ, @MicroProofs)
• A new function minted_to_dict akin to to_dict to turning MintedValue to Dict. (@dmitrystas)

Changed

Warning

BREAKING-CHANGE
Specialized all Dict's key to ByteArray, and thus remove the need for passing an extra comparison function in many functions. Dict are however still specialized with a phantom type for keys.

Warning

BREAKING-CHANGE
Few functions from Dict have been renamed for consistency:

• from_list -> from_pairs
• from_ascending_list -> from_ascending_pairs
• to_list -> to_pairs

Removed

N/A

Full Changelog

1.8.0...1.9.0

1.8.0

compiler compatiblity
< v1.0.28-alpha
>= v1.0.25-alpha

Added

• value.reduce to efficiently fold over a value and its elements. @micahkendall

• value.from_asset_list to turn an asset list into a Value while enforcing invariants expected of Value. @MicroProofs @KtorZ

• math.is_sqrt as a more efficient alternative to sqrt. @francolq

Changed

• Disclaimers in documentation to bytearray.to_string and string.from_bytearray regarding UTF-8 encoding. @KtorZ

Removed

N/A

1.7.0

Added

• list.index_of: For getting a values index in a list.
• transaction.placeholder: For constructing test transactions.
• transaction.value.is_zero: For checking whether a value is null.

Changed

• value.to_minted_value now correctly preserves the invariant of MintedValue: it always contain a null quantity of Ada.

1.6.0

Added

• math.pow2: For faster exponentions for powers of two.
• bytearray.test_bit: For testing if a bit is set in a bytearray (MSB).

1.5.0

Removed

• retired list.and and list.or because of the new keywords for logical op chaining.

1.4.0

Changed

• Fixed missing null-check on value.add. Adding a null quantity of token is now correctly a no-op.

1.3.0

Added

• math.sqrt: For calculating integer square roots using a quadratically convergent method _{@KtorZ, @logicalmechanism}
• math/rational.numerator & math/rational.denominator: For accessing parts of a rational value. _{@KtorZ, @micahkendall}
• math/rational.arithmetic_mean: For computing arithmetic mean of rational values. _@KtorZ
• math/rational.geometric_mean: For computing geometric mean of two rational values. _{@logicalmechanism}

Changed

• Clear empty asset lists in Value on various operations. Before that fix, it could happen that removing all assets from a given policy would lead to an empty dictionary of assets still be present in the Value. _{@logicalmechanism}

• Fixed few examples in the documentation. _{@ariady-putra}

Removed
