0.0.0.1

• First version of the package.

0.0.0.2

• Created the modules; "Factory.Test.QuickCheck.Bounds", "Factory.Math.Implementations.Pi.Borwein" & "Factory.Test.Performance.Statistics".
• Created a new module "Factory.Data.PrimeFactors", and migrated definitions from modules "Factory.Math.PrimeFactorisation" & "Factory.Math.Implementations.PrimeFactorisation".
• Created the class Factory.Math.Factorial.Factorial and a new module "Factory.Math.Implementations.Factorial".
• Moved existing implementation (Bisection) into the new module, with a new implementation (PrimeFactorisation).
• Added the function Factory.Math.Summation.sumR.
• Added a parameter to the functions Factory.Math.DivideAndConquer.divideAndConquer and Factory.Data.Bounds.divideAndConquer, to permit asymmetric bisection.
• Added methods to class Factory.Math.Pi.Algorithm to permit the retrieval of Pi as a Rational or a String.
• Renamed the function Factory.Math.Precision.capPrecision to Factory.Math.Precision.simplify.
• Removed the module "Factory.Test.Performance.Exponential".
• Removed the function Factory.Math.Power.raise, which was no more efficient than ghc's implementation of (^).
• Uploaded to Hackage.

0.1.0.0

• Amended the .cabal-file to more correctly specify the dependency on package "toolshed".
• Added the module "Factory.Math.Probability".
• Renamed the module "Factory.Data.Bounds" to "Factory.Data.Interval", and added the functions; Factory.Data.Interval.precisely, Factory.Data.Interval.shift, Factory.Data.Interval.closedUnitInterval.
• Guarded flag "eager-blackholing" in the cabal-file.

0.1.0.1

• Renamed classes Factory.Math.[Primality, Pi, Factorial, SquareRoot, PrimeFactorisation].Algorithm to Factory.Math.[Primality, Pi, Factorial, SquareRoot, PrimeFactorisation].Algorithmic, to distinguish them from the data-types which implement them.
• Added the modules;
  • "Factory.Math.Hyperoperation",
  • "Factory.Test.QuickCheck.Hyperoperation",
  • "Factory.Test.Performance.Hyperoperation".
• Added the modules
  • "Factory.Math.Primes",
  • "Factory.Math.Implementation.Primes",
  • "Factory.Test.Performance.Primes",
  • "Factory.Test.QuickCheck.Primes"
  • "Factory.Data.PrimeWheel".
• Added the function Factory.Math.PrimeFactorisation.squareFree.
• Added rewrite-rules to specialise Factory.Math.Power.isPerfectPower for type-parameter=Int.
• Recoded module "Factory.Math.Radix" to the interface Data.Array.IArray.IArray, rather than the data-type Data.Array.Array.

0.1.0.2

• Added Factory.Math.Primes.primorial.
• Altered Factory.Math.Implementations.Primes.trialDivision to take an integer defining the size of a Factory.Data.PrimeWheel, from which candidates are extracted.
• Removed the command-line option primesPerformanceGraph, which appears to memoise data from previous tests.
• Uploaded to Hackage.

0.1.0.3

• Qualified Factory.Math.Implementations.Primes.trialDivision with pragma "NOINLINE", to block optimization which conflicts with rewrite-rule for Factory.Math.Implementations.Primes.sieveOfEratosthenes !
• Re-coded Factory.Data.PrimeWheel.coprimes and Factory.Math.Implementations.Primes.sieveOfEratosthenes, to use a map of lists, rather than a map of lists of lists.

0.2.0.0

• Separately coded the special-case of a Factory.Data.PrimeWheel of size zero, in Factory.Math.Implementations.Primes.trialDivision, to achieve better space-complexity.
• Added Factory.Data.PrimeWheel.estimateOptimalSize.
• Split module "Factory.Math.Implementations.Primes" into;
  • "Factory.Math.Implementations.Primes.SieveOfEratosthenes",
  • "Factory.Math.Implementations.Primes.TurnersSieve",
  • "Factory.Math.Implementations.Primes.TrialDivision",
  • and added a new module "Factory.Math.Implementations.Primes.SieveOfAtkin". This makes the rewrite-rules less fragile.
• Coded Factory.Math.Radix.digitalRoot more concisely.
• Split module "Factory.Math.Power" into an additional module "Factory.Math.PerfectPower".
• Replaced (+ 1) and (- 1) with the faster calls succ and pred.
• Used Paths_factory.version in Main, rather than hard-coding it.

0.2.0.1

• Changed by Lennart Augustsson, to replace System with System.Environment and System.Exit, and to remove dependency on haskell98.

0.2.0.2

• Reacted to new module-hierarchy and addition of method ToolShed.SelfValidate.getErrors, in package "toolshed-0.13.0.0".
• Made Factory.Data.Interval.getLength private.
• Added Factory.Data.Interval.mkBounded.
• Generalised Factory.Math.Statistics to accept any Data.Foldable.Foldable Functor, rather than merely lists.

0.2.0.3

• Added class Show to some contexts in Factory.Math.Radix, for migration to ghc-7.4.

0.2.0.4

• Added classes Eq and Show to many contexts, for migration to ghc-7.4.
• Minor re-formatting.

0.2.0.5

• Minor clarification of Factory.Math.Implementations.Primality.witnessesCompositeness.
• Added details to any failure to parse the command-line arguments.
• Defined package's name using program's name, in module "Main.hs".
• Added Factory.Math.Primes.mersenneNumbers.
• Replaced use of mod on positive integers, with the faster rem, in;
  • Factory.Math.Implementations.Pi.Spigot.Spigot.processColumns,
  • Factory.Math.Implementations.Primality.witnessesCompositeness,
  • Factory.Math.Implementations.Primes.TrialDivision.isIndivisibleBy,
  • Factory.Math.Implementations.Primes.SieveOfAtkin.polynomialTypeLookup,
  • Factory.Math.Implementations.Primes.SieveOfAtkin.findPolynomialSolutions,
  • Factory.Math.Implementations.Primes.TurnersSieve.turnersSieve,
  • Factory.Math.PerfectPower.maybeSquareNumber.
• Replaced calls to realToFrac with toRational in;
  • Factory.Math.Implementations.SquareRoot,
  • Factory.Math.Statistics.getDispersionFromMean,
  • Factory.Math.SquareRoot.getDiscrepancy,
  • Factory.Math.SquareRoot.getAccuracy, to more clearly represent the required operation.

0.2.1.0

• Refactored Factory.Test.QuickCheck.QuickChecks.
• Remove redundant import of Data.Ratio from many modules.
• Refactored Factory.Math.Radix.encodes to make use of Data.List.genericLength, & removed empty keyword where.
• Explicitly closed standard-input in the executable.
• Replaced calls to error from inside the IO-monad, with Control.Monad.fail.
• Added function Factory.Math.Precision.roundTo.
• Trapped command-line arguments to which garbage has been appended.
• Corrected the output of Main.main.optDescrList.printVersion.
• Removed the integral population-size parameter from Factory.Math.Probability.generateContinuousPopulation & Factory.Math.Probability.generateDiscretePopulation, making the result conceptually infinite.
• Created class Factory.Math.Probability.Distribution, to which data-types Factory.Math.Probability.ContinuousDistribution & Factory.Math.Probability.DiscreteDistribution conform.
• Added data-constructors Factory.Math.Probability.ExponentialDistribution, Factory.Math.Probability.ShiftedGeometricDistribution & Factory.Math.Probability.LogNormal.
• Added command-line option "--plotDiscreteDistribution" to Main.
• Removed Preprocessor-check on the version of package "toolshed", in modules "Factory/Math/Summation" & "Factory/Data/PrimeFactors".

0.2.1.1

• Added Factory.Test.QuickCheck.Probability.prop_logNormalDistributionEqual.
• Removed pragma INLINE from Factory.Math.Implementations.Primes.TrialDivision.isIndivisibleBy, since to be effective it must be called with fully applied parameters (which it isn't).
• Un eta-reduced Factory.Math.Power.square, since we want it to be inlined when called with one argument.
• Tested with haskell-platform-2013.2.0.0.
• Replaced preprocessor-directives with build-depends constraints in the .cabal-file.
• Added function Factory.Math.Statistics.getWeightedMean & corresponding tests in module "Factory.Test.QuickCheck.Statistics".
• Since (<$>) is exported from the Prelude from base-4.8, imported Prelude hiding (<*>) into module "Factory.Data.Monomial", since this symbol is defined locally for other purposes.
• Either replaced instances of (<$>) with fmap to avoid ambiguity between Control.Applicative & Prelude which (from base-4.8) also exports this symbol, or hid the symbol when importing the Prelude.

0.2.1.2

• Hid (<$>) when importing the Prelude into module "src/Factory/Test/QuickCheck/Pi".
• Added the compiler to the output returned for the command-line option "version".
• Changed flag "threaded" in the .cabal-file to "manual".
• Added Default-language-specification to the .cabal-file.
• Added file "README.markdown".
• Converted this file to markdown-format.
• Replaced System.Exit.exitWith (System.Exit.ExitFailure 1) with System.Exit.exitFailure & System.Exit.exitWith System.Exit.ExitSuccess with System.Exit.exitSuccess.
• Moved the entry-point to the test-suite from module "Main.hs" to "Test.hs", both to integrate with cabal & to minimise the dependencies of the executable.
• Partitioned the source-files into directories "src-lib", "src-exe", & "src-test", & referenced them individually from the .cabal-file to avoid repeated compilation.
• Used CPP to control the import of symbols from Control.Applicative.

0.2.2.0

• Corrected the markdown-syntax in this file.
• Reverted to calling "error" rather than "Control.Monad.fail", since the String-argument for the latter is discarded in Monad-implementations other than IO.
• Uploaded to GitHub.
• Simplified file src-test/Main.hs.
• Added file .travis.yml to control testing by https://docs.travis-ci.com.
• Added file .ghci.
