Full Changelog: 1.50.0.0...1.51.0.0

1.50.0.0

plutus-core

Removed

• Removed the caseList and caseData builtins in preparation for adding direct Caseing on lists and Data.

Added

• In #7029 added support for Caseing on booleans and integers. For example, case True a b now evaluates to b.

• Added a new UPLC optimisation which removes force when applied to case expressions where each branch contains a delay at the top, or if the delay is under any number of lambda abstractions.

• Added a new emitter mode logWithCallTraceEmitter which uses trace messages generated by PlutusTx.Plugin:profile-all flag of plutus-tx-plugin to create call trace of the functions that led to the evaluation failure. If script passes or script is not compiled with profile-all flag, logWithCallTraceEmitter will behave as regular logEmitter.

• Added support for Caseing on builtin lists. When Caseing a builtin list, exactly one or two branches are allowed: with a single branch, Case assumes the list is non-empty and applies the head element and the tail to that branch; with two branches, the first branch is selected if the list is empty (and takes no arguments), and the second branch is chosen if the list is non-empty, receiving the head element and the tail as its arguments. Note, the single branch WILL FAIL the script evaluation if empty list is given.

Changed

• Drop hex-text package in favor of base16-bytestring.

• Disable Plutus executable build for wasm

plutus-ledger-api

Added

• PlutusLedgerApi.Envelope module with two functions:
  • compiledCodeEnvelope: creates a JSON envelope for CompiledCode with a description.
  • writeCodeEnvelope: writes a JSON envelope for CompiledCode to a file.

plutus-tx

Added

• Module 'PlutusTx.Test.Util.Compiled' of the 'plutus-tx-testlib' package got a new function 'countFlatBytes' that counts the size of a 'CompiledCode' in Flat bytes.

1.47.0.0

plutus-core

Changed

• In #7106 improved error reporting in the evaluators.

• StructuralEvaluationError and OperationalEvaluationError were renamed to StructuralError and OperationalError respectively.

• _MachineError was made obsolete in favor of _StructuralError.

• The tags for the flat encodings of the as-yet-unreleased dropList,
  lengthOfArray, listToArray, indexArray, caseList and caseData
  built-in functions have been changed pending the possible removal of
  caseList and caseData.

No changes.

plutus-tx

Added

• PlutusTx.Test.Run.Code module was added to the plutus-tx:testlib package.
  This module provides a way to run compiled Plutus code in a test environment,
  allowing for easier testing and debugging of Plutus scripts. See more details in the User Guide.

• Added over 30 new functions to PlutusTx.BuiltinList

• Added new errors codes:

  • PT23 -> PlutusTx.BuiltinList.head: empty list
  • PT24 -> PlutusTx.BuiltinList.tail: empty list
  • PT25 -> PlutusTx.BuiltinList.last: empty list

• Added TH help PlutusTx.IsData.TH.makeIsDataAsList which generates ToData, FromData, UnsafeFromData instances with internal representation being Data.List instead of Data.Constr for given product datatype(only having a single constructor).

• Added PlutusTx.Test.Util.compiledCodeToHask and PlutusTx.Test.Util.compiledCodeToHaskUnsafe for applying parameters to CompiledCodeIn uni fun tersely.

• Added PlutusTx.Test.Golden.goldenCodeGen for generating golden of the generated code from Template Haskell.

• Added assertResult for asserting given CompiledCode Bool evaluates True.

Changed

• BuiltinList lookup is made cheaper by using the DropList builtin function.

plutus-tx-plugin

Added

• Integrated the compiler certifier into the plugin. This feature can be accessed using the certify plugin option. Note that this is currently very experimental, and is released now mainly for testing purposes.

• Added support for integerEq into the plugin, enabling use of (==) @Integer and pattern matching on Integer type values.

Full Changelog: 1.46.0.0...1.47.0.0

1.46.0.0

plutus-core

Removed

• GHC 8.10 is no longer supported. The supported GHC versions are 9.6 (primary), 9.8, and 9.10.

Added

• In #7042 implemented force-delay cancellation when delays appear under ifThenElse

Changed

• When logs preservation is disabled compiler will inline even "impure" terms
  that are determined to be eventually evaluated anyway.

• Enhanced PIR's StrictifyBindings pass with strictness analysis, allowing
  many more non-strict bindings to be strictified, thereby reducing overhead.

plutus-ledger-api

Removed

• GHC 8.10 is no longer supported. The supported GHC versions are 9.6 (primary), 9.8, and 9.10.

plutus-tx

Removed

• GHC 8.10 is no longer supported. The supported GHC versions are 9.6 (primary), 9.8, and 9.10.

plutus-tx-plugin

Removed

• GHC 8.10 is no longer supported. The supported GHC versions are 9.6 (primary), 9.8, and 9.10; plutus-tx-plugin is only supported on GHC 9.6.

Fixed

• In some cases HEX-encoded string literals were not handled correctly,
  causing the "Use of fromString @ PlutusTx.Builtins.HasOpaque.BuiltinByteStringHex with inscrutable content" error.

plutus-executables

No changes.

Full Changelog: 1.45.0.0...1.46.0.0

1.45.0.0

plutus-core

Changed

• Builtin functions are pure when partially applied. Fully applied builtins are impure, as well as incorrectly applied ones (e.g. term argument applied instead of a type argument).

plutus-ledger-api

No changes.

plutus-tx

Added

• Module PlutusTx.BuiltinList, containing functions for operating on BuiltinList.

Changed

• PlutusTx.List.indexBuiltinList is replaced by PlutusTx.BuiltinList.!!.

plutus-tx-plugin

No changes.

plutus-executables

No changes.

Full Changelog: 1.44.0.0...1.45.0.0

1.44.0.0

plutus-core

Fixed

• Fixed a bug in PIR's callsite inliner that caused it to skip valid inlining in certain cases.

plutus-ledger-api

No changes.

plutus-tx

Removed

• Removed Data.AssocMap.toDataList because it suffers from the bug described in #6085.

Added

• PlutusTx.Data.List.destructList, which takes a list along with a list of
  desired indices, and generates variables bound to the elements at those indices.

• PlutusTx.Data.List.caseList and caseList', for matching on Lists.

Changed

• PlutusTx.Lift.liftCode and related functions now apply the default PIR and UPLC
  optimizations during code lifting. To disable these optimizations, use liftCodeUnopt
  and related functions.

• PlutusTx.Prelude no longer re-exports PlutusTx.List. There are now two separate
  list modules: PlutusTx.List and PlutusTx.Data.List. Pick the one that fits your
  use case and import it explicitly.

• PlutusTx.Prelude no longer re-exports PlutusTx.Foldable or PlutusTx.Traversable.
  These typeclasses are generally discouraged due to their performance overhead.
  For example, instead of using PlutusTx.Foldable.foldMap, consider rewriting
  your code using PlutusTx.List.foldr.

• PlutusTx.Prelude now re-exports BuiltinBool, BuiltinList, BuiltinPair,
  ToData, FromData and UnsafeFromData.

plutus-tx-plugin

Added

• Plinth compiler flag inline-callsite-growth, for setting the inlining threshold
  for callsites. 0 disables inlining a binding at a callsite if it increases the AST size;
  n allows inlining if the AST size grows by no more than n. Keep in mind that
  doing so does not mean the final program will be bigger, since inlining can often
  unlock further optimizations.

plutus-executables

No changes.

Full Changelog: 1.43.0.0...1.44.0.0

1.43.0.0

plutus-core

No changes.

plutus-ledger-api

Added

• Added a Data-backed version of MintValue for Plutus V3.

Changed

• The Data-backed V3 ScriptContext is updated to now use the Data-backed MintValue, similar to how the SOP ScriptContext uses the SOP MintValue.

plutus-tx

Added

• Added more standard library functions to Data.List.

• Added new conversion functions from Data-backed Map and Data-backed List.

• New Data.AssocMap library functions: filter, mapWithKey, mapMaybe and mapMaybeWithKey.

Changed

• The conversion functions between Data.AssocMap.Map and different kinds of lists are now named according to which type of list they support.

• Slightly improved the performance of some of the existing Data.AssocMap functions.

plutus-tx-plugin

No changes.

plutus-executables

No changes.

Full Changelog: 1.42.0.0...1.43.0.0

1.42.0.0

plutus-core

Added

• Switch from cryptonite library to crypton (a drop in replacement).

• DropList builtin functionality

• Costing model for the DropList builtin

• A new type BuiltinArray.

• Three functions for working with BuiltinArray values:

  • listToArray (converts a list to a BuiltinArray)
  • indexArray (returns an element of a BuiltinArray by index)
  • lengthOfArray (returns the length of a BuiltinArray)

Fixed

• Fixed a bug in Plutus IR's dead code elimination pass that could incorrectly remove
  live data constructors or destructors.

plutus-ledger-api

Changed

• Remove un-needed dervied Typeable instances.

plutus-tx

Added

• PlutusTx.Function.fix, Plinth's equivalent of Data.Function.fix.

• Module PlutusTx.Optimize.SpaceTime, containing utilities for space-time tradeoff,
  such as recursion unrolling.

• Added PlutusTx.Data.List.null.

• Added PlutusTx.Optimize.Inline.inline. This works like GHC.Magic.inline, and can be used
  in the form of inline f or inline (f args).

• Added more functions to PlutusTx.Data.List.

Changed

• Remove un-needed dervied Typeable instances.

• Allow PlutusTx.Optimize.Inline.inline to inline local bindings.

• Removes the constructor id check from the code AsData generates for product types, resulting in better performance.

plutus-tx-plugin

Changed

• Changed the default value of compiler flag PlutusTx.Plugin:preserve-logging to true.

• The Plinth compiler now inlines fixed point operators by default. This can be turned
  off by using no-inline-fix or conservative-optimisation.

• The Plinth inliner now inlines local bindings (in addition to top-level bindings)
  with INLINE pragmas.

• AsData now avoids creating strict dead bindings (which were previously created for
  unused fields).

plutus-executables

No changes.
