# Changelog
## v1.0.12-alpha - unreleased
### Added
- **aiken**: added a `blueprint policy` command to compute the policy ID of a minting script
### Fixed
- **aiken-lang**: Prevent mutual recursion caused by conflicting function names for generic expect type
- **aiken-lang**: UPLC evaluation of large integers literals (> max u64)
- **aiken-lang**: Parsing of error / todo keywords in when cases
- **aiken-lang**: Parsing of negative integer patterns and constants
### Changed
### Removed
## v1.0.11-alpha - 2023-06-23
### Added
- **aiken**: enhance `aiken new`
- **aiken-lang**: Binary operator are now treated like first-class citizen in
expressions. In particular, they can be used as function arguments directly:
```
compare_with(a, >=, b) == compare_with(a, fn(l, r) { l >= r }, b)
```
- **aiken-lang**: Make traces produced by expect dependent on the value of the
tracing flag.
### Fixed
- **aiken-lang**: Explain discards and expect a bit better in the unused var warning
- **aiken-lang**: Fix expect \_ = ... not including the cast from data logic if the type is data and right hand has a type annotation
- **aiken-lang**: Fix for the final clause of a when expecting another clause
afterwards in nested list cases.
- **aiken-lang**: Fix for all elements were being destructured in tuple clauses
even if not used.
- **aiken-lang**: Fix for tuple clause not consuming the next case causing
incomplete contracts. Now tuple clause will always consume the next case
unless it is the final clause
- **aiken-lang**: Fix for builtins using the incorrect data to type conversion when used as a function param.
## v1.0.10-alpha - 2023-06-13
### Added
- **aiken**: added panic hook to present a link to make a bug report
### Fixed
- **aiken-lang**: fmt for `module.Constr { field: value }`
- **aiken-lang**: Issue where using var pattern in a when was passing the constr
index instead of the constr
- **aiken-lang**: Issue where expecting on a list had unexpected behaviors based
on list length.
- **aiken-lang**: Issue where expecting on a list from data was using the wrong
expect cast for the list tail.
### Removed
N/A

### Added

separator (e.g. `1_000_000`)

- **aiken-lang**: fixed operator precedences, in particular the pipe operator
(`|>`) which is now of the lowest precedence.

leading to type issues
