Changes to version 3.5.0:
Changes to version 3.4.2:
tmpdiradded to RC file (
~/.pakcsrc) in order to redefine the location of a temporary directory (e.g., if the default location
/tmpis not writable for the PAKCS process).
dynamicmessagesremoved from RC file since they are no longer used.
:setwhen verbosity level is greater than 1.
Changes to version 3.3.0:
:typefor expressions with free variables corrected.
Monadcontext are specialized to
Datacontext are specialized to
Floatingcontext are specialized to
newtypedeclarations integrated into the compiler. Thus, the FlatCurry files produced by the front end contain
newtypedeclarations which are eliminated before the Prolog code is generated.
Changes to version 3.2.0:
(=:<=)changed from external to defined operations that call the external operations
nonstrictEq, respectively. This is meaningful to keep the
(=:<=)whereas external operations have no class contexts.
pakcsinitrcis no longer used.
Changes to version 2.3.0: bug fixes and
aValue(non-deterministic value generator) added to the prelude. For each
Datainstances for the defined type are automatically derived as long as the defined type is first-order (i.e., does not contain functional types). Free variable have type class constraint
Data. The motivation for this design and its advantages are described in a DECLARE/WFLP'19 paper.
ReadShowTermremoved (now available in packages
System.Processis available in package
process. The rest remains in the library.
lib/Prelude.curryis written to
lib/.curry/pakcs-3.2.0/Prelude.fcy(and similarly all other intermediate files). This avoids inconsistencies of intermediate files when different Curry systems are used.

Changes to version 2.0.0:
-cpmexecadded to script
This version has almost the same functionality as version 1.15.0 but adds type classes similar to Haskell 98. In addition to version 1.15.0 and type classes, this version contains the following changes:
definecommand removed (since it was based on a quite restricted parser)
+free) removed since it has many restrictions and is no longer compatible with type classes.
pakcs --base-versionor inside Curry programs by the operation
Distribution.baseVersion. The versioning of base libraries is intended to be used by CPM.

Changes to version 1.14.0:
Database.ERD...added (formerly part of ER currytools).
Globaluse system commands
lockfilefor internal file synchronization in order to remove dependency on package
Natfor Peano numbers added.
Rewriting.*for term rewriting in Curry extended to deal with rewriting strategies, narrowing strategies, critical pairs, definitional trees.
Sort: ...Sort operations renamed to ...SortBy and ...Sort operations with standard ordering added.
Statewith an implementation of the state monad added.
Test.EasyChecksplit into two modules to have less import dependencies when putting properties into a module.
Test.Propadded as a clone of
Test.EasyCheckwhich defines the interface but no implementation so that it does not import any other library. import dependencies when putting properties into a module.
contractsto transform contracts (specifications, pre/postconditions) into run-time assertions.
cpns(Curry Port Name Server) and
www(web scripting) moved to

curry checksupports also testing with float arguments.
PAKCSINSTALLDIRto specify the location where PAKCS is moved after the build process.
Changes to version 1.13.0:
Successis now a type synonym for
successis defined as
Truein the prelude.
Prelude.compareand related comparison operations are flexible (instead of rigid as before) on user-defined datatypes. It still suspends when comparing two variables or one variable with a number or character.
RandomValueadded (currently only supported by SWI-Prolog)
getLoadPathForFile) removed since they are deprecated (use operations like
lookupModuleSourceInLoadPathinstead of the deprecated operations since they handle hierarchical module names better)
meta/*removed (since they have been replaced by libraries with hierachical names, see below)
import FlatCurry.Types import FlatCurry.Files
currycheckfor automated test execution added
Changes to version 1.13.0:
import AbstractCurry.Types import AbstractCurry.Files
import AbstractCurry.Select import AbstractCurry.Build
CLP.FDadded: its functionality is similar to the old library
CLPFD, but the interface is different so that other FD constraint solvers are easier to connect.
Changes to version 1.12.0:
Prelude.==is flexible (instead of rigid as before). It still suspends when comparing two variables or one variable with a number or character. However, if
Prelude.==is (positively) used in conditions of rules, it is automatically transformed into a unification constraint so that it does not suspend.
Pretty: code and interface updated, e.g., some combinators renamed and new combinators added (e.g., to support ANSI formatting and colorisation of documents)
Changes to version 1.11.5:

FlatCurryadapted for this purpose.
CHRcompiledto implement Constraint Handling Rules in Curry added together with various examples in
Changes to version 1.11.3:
+freeis not set.
:load ~/revloads module
revfrom the home directory.
editaccepts module names (instead of arbitrary file names).

pakcs :set v2 :load rev). Old options (except setting of
.pakcsrcproperties) are no longer necessary and, thus, not supported.
:save: if no argument is given, the executable is saved with the initial expression

divchanged (to be compatible with Haskell) and
Distribution: front-end parameters extended by supporting "special" (i.e., aribrary) arguments.
Distribution: front-end paramter
outfileremoved and front-end parameter
FlatCurry: after calling the front end, an exception is raised if the front end returns with an error (due to an illegal source program).
Integer: Power operators added.
Float: hyperbolic/ arc sine/cosine/tangent operators added.
formMetaInfoadded, HTML header changed to HTML5.
erd2curryupdated to new version with support for SQLite database. Bug fix in code generation w.r.t. checking of cardinality constraints.

Changes to version 1.11.1:
progare now stored in the file
prog.stateas in previous releases).
HTML: default (white) background for body of generated web pages removed (since this is usually defined in css files).
IO: Fixed a bug in
hGetLinewhich caused an end-of-file error when reading a non-empty line without a newline termination.
currytools/typeinference) added. This tool can be used to annotate expressions in FlatCurry programs with their type.
Changes to version 1.11.0:
FlatCurryextended to represent typed expressions by a new constructor
Changes to version 1.10.1:
fcaseexpressions and non-linear patterns in left-hand sides of program rules.

=" in the old syntax).
