1.61.0.0

plutus-core

Added

• Roundtrip and stable byte encoding tests for all Flat instances across
  flat, plutus-core, plutus-ir, and untyped-plutus-core packages.
• Standalone encoding generator executable (cabal run flat-encoding-generator)
  for reproducing expected byte constants.

Fixed

• Fixed consClose in the Flat decoder failing to advance the stream pointer past 1 byte, which corrupted decoder state for Generic-derived Flat instances of large enums (>256 constructors) and caused infinite memory consumption during deserialization.

plutus-ledger-api

No changes.

plutus-tx

No changes.

plutus-tx-plugin

Changed

• The plugin now automatically sets the Strict extension and the GHC flags mentioned
  in https://plutus.cardano.intersectmbo.org/docs/using-plinth/extensions-flags-pragmas.
  The Strict extension can be turned off using plugin flag no-strict.
  Requires compiling with plinthc or plc instead of compile.

Fixed

• Fixed a 3-5x execution cost regression for unsafeFromBuiltinData on multi-constructor
  types when compiling in SumsOfProducts mode (the default). The caseInteger fallback
  now generates equalsInteger/ifThenElse chains instead of building a linked list at
  runtime.

plutus-executables

No changes.

plutus-metatheory

Added

• Added a compiler certification pass for the force-case-delay optimization.

Changed

• The certifier can now report execution budget before and after each pass.

Full Changelog: 1.60.0.0...1.61.0.0

1.60.0.0

plutus-core

Added

• A new UPLC optimization pass, turning multi-argument applications into case-constr form.

Changed

• The uplc executable now accepts serialised scripts (in addition to textual
  and flat-encoded). Use --input-format serialised.

plutus-ledger-api

Added

• Added ScriptContextBuilder test utility (PlutusLedgerApi.Test.ScriptContextBuilder) to plutus-ledger-api-testlib for constructing realistic ScriptContext values in tests using a composable builder pattern.

Fixed

• Fixed Show instance for TokenName displaying non-printable token names as
  seemingly empty strings. Token names are now always shown as hex-encoded bytes,
  matching CurrencySymbol (#7638).

plutus-tx

Added

• asData now generates a destructor function for the data type, in addition to the
  pattern synonyms. For sum types, it is better to use the destructor function than the
  pattern synonyms to match on them.

plutus-tx-plugin

Added

• Added Plinth.Plugin, which uses a typeCheckResultAction to preserve more
  source locations, resulting in clearer error messages.

Changed

• Improved compilation error messages by making them more concise and including
  the relevant code snippet.

• Improved error reporting in the Plinth compiler for certain unsupported Haskell features.
  Requires compiling with plinthc or plc instead of compile.

plutus-executables

No changes.

plutus-metatheory

Added

• Translation relation and decision procedure for the ApplyToCase pass.

Full Changelog: 1.59.0.0...1.60.0.0

1.59.0.0

plutus-core

Added

• Added certifier hints in Haskell and Agda.
  They are useful for certifying certain UPLC optimizations such as inlining, since their translation relations are otherwise computationally difficult to decide.

Changed

• Relaxed the upper bound for the cardano-crypto-class dependency (< 2.4)

• Added an Agda checking procedure for the inliner, and updated the UPLC inliner to emit certifier hints.

plutus-ledger-api

Changed

• Replace hand-written PlutusTx.Eq instances with deriveEq across all V1/V2/V3 types

• Add PlutusTx.Eq instance for MintValue

• Replace hand-written PlutusTx.Ord instances with deriveOrd for V1.Extended and V3.ProtocolVersion

plutus-tx

Added

• A deriveOrd command to derive PlutusTx.Ord instances for datatypes/newtypes, similar to Haskell's
  deriving stock Ord

• PlutusTx.deriveEq: Template Haskell function to derive PlutusTx.Eq instances
  for datatypes and newtypes, similar to Haskell's deriving stock Eq
