0.9.0.0
	* First version of the package.
0.10.0.0
	* Created "src/ToolShed/" sub-directory & then modified module-names accordingly.

	* Added a makefile.
	* Qualified identifiers used in error-messages.
0.10.0.1

0.10.2.0
	* Renamed package from 'ToolShed' to 'toolshed', for compatibility with Debian's ".deb"-format.
0.11.0.0
	* Added manually controlled "llvm" flag to "toolshed.cabal".
	* Removed the module "ToolShed.Package", for which 'Distribution.Package.PackageIdentifier' is a suitable alternative.

	* Relocated 'mean' & 'nCr' from "ToolShed.Arithmetic", to the package "factory".
	* Added function 'ListPlus.groupComparing'.
	* Changed identifier for type-parameters, to better reflect its role.
	* Relocated the remaining rather pointless functions from the module "ToolShed.Arithmetic" & deleted it.
	* Added module "ToolShed.Defaultable", & derived class 'ToolShed.Options.Options' from it.
0.11.1.0
	* Added functions 'merge' & 'mergeBy' to module "ToolShed.ListPlus" & exported a new type-synonym 'ToolShed.ListPlus.ChunkLength'.
	* Uploaded to <http://hackage.haskell.org/packages/hackage.html>.
0.12.0.0
	* Added modules "ToolShed.TimeAction" to measure the CPU-seconds required for an IO-action, & "Pair".
0.12.0.1
	* Removed unnecessary type-context 'Ord' from 'ToolShed.ListPus.mergeBy' & reimplemented 'ToolShed.ListPus.merge' in terms of 'ToolShed.ListPus.mergeBy'.
	* Added 'ToolShed.ListPlus.runLengthEncode' & 'ToolShed.ListPlus.runLengthDecode'.
0.13.0.0
	* Removed module "ToolShed.Unsafe".
	* Renamed:
		"ToolShed.ListPlus" to "ToolShed.Data.List"
		"ToolShed.Pair" to "ToolShed.Data.Pair"
		"ToolShed.TimeAction" to "ToolShed.System.TimeAction"
		"ToolShed.TimePure" to "ToolShed.System.TimePure"
	* Migrated 'ToolShed.Data.List.RunLengthCode' & associated functions, into a new module "ToolShed.Data.List.Runlength".
	* Migrated 'ToolShed.Data.List.Splits' & associated functions, into a new module "ToolShed.Data.List.Splits".
	* Replaced function 'ToolShed.Data.List.groupComparing' with the more useful 'ToolShed.Data.List.equalityBy', which can be used with either 'Data.List.groupBy' or 'Data.List.nubBy'.
	* Added instances of 'ToolShed.SelfValidate.SelfValidator' for 'Data.Maybe.Maybe' '(,)', 'Data.Set.Set', 'Data.Map.Map' & 'Data.Array.IArray.Array'.
	* Added instance of 'ToolShed.Defaultable.Defaultable' for '(,)'.
	* Added functions 'ToolShed.Data.List.showListWith', 'ToolShed.Data.List.permutations', 'ToolShed.Data.List.gatherBy', 'ToolShed.Data.List.findConvergenceBy', 'ToolShed.Data.List.findConvergence', 'ToolShed.Data.List.gather'.
	* Added modules "ToolShed.System.File" & "ToolShed.System.Random".
	* Added method 'ToolShed.SelfValidate.getErrors', & supporting functions 'ToolShed.SelfValidate.getFirstErrors' & 'ToolShed.SelfValidate.extractErrors'.
	* Create module "ToolShed.Arbitrary.*".
	* Added "Main", "ToolShed.Test.QuickChecks" & "ToolShed.Test.Data.List" to facilitate testing.
	* Removed 'ToolShed.Data.Pair.both'.
	* Replaced "System" with "System.Environment" & "System.Exit".
	* Removed dependency on "haskell98".
0.14.0.0
	* Defined package's name using program's name, in "Main.hs".
	* Checked package "Base" exports 'Data.Tuple.swap', in "ToolShed.Arbitrary.Array".
	* Relocated "ToolShed.Arbitrary" to "ToolShed.Test.QuickCheck.Arbitrary".
	* Added "ToolShed.Test.ReversibleBoundedEnum", "ToolShed.Test.ReversibleEnum", "ToolShed.Test.ReversibleIO", & "ToolShed.Test.SelfValidate".
	* Amended 'ToolShed.System.File.locate' to deal with absolute file-paths.
	* Replaced legacy calls to 'Data.Map.fold' & 'Data.Set.fold', with more expicit calls to 'Data.Map.foldr' & 'Data.Set.foldr' from a more recent version of the "containers" package.
	* Added instance of 'ToolShed.SelfValidate.SelfValidator' for '(,,)'.
	* Trapped null list in 'ToolShed.System.Random.select'.
	* Added functions "ToolShed.Data.List.nub'" & 'ToolShed.Data.List.hasDuplicates'.
	* Migrated functions 'gather', 'gatherBy', 'hasDuplicates' which merely operate on 'Data.Foldable.Foldable' types from module "ToolShed.Data.List", into new module "ToolShed.Data.Foldable".
0.15.0.0
	* Refactored 'ToolShed.Test.QuickChecks'.
	* Added type 'ToolShed.Data.List.Matches' & function 'ToolShed.Data.List.permutationsBy'.
	* Trapped the case of a null list supplied to 'ToolShed.Data.List.permutationsBy'.
	* Re-implemented 'ToolShed.System.Random.shuffle', using the Fisher-Yates algorithm; which also improved the efficiency.
	* Trapped special cases in 'ToolShed.System.Random.generateSelection'.
	* Added modules "ToolShed.Test.System.Random", "ToolShed.Data.Triple", "ToolShed.Data.Quadruple", "ToolShed.Test.Data.Triple", & "ToolShed.Test.Data.Quadruple".
	* Explicitly closed standard-input in the executable.
	* Replaced calls to 'error' from inside the IO-monad, with 'Control.Monad.fail'.
	* Added an instance for '(,,)', to "ToolShed.Defaultable.Defaultable".
	* Corrected version-string in "Main" used in '--version' option.
	* Corrected the output of 'Main.main.optDescrList.printVersion'.
0.15.0.1
	* Tested with 'haskell-platform-2013.2.0.0'.
	* Replaced preprocessor-directives with 'build-depends' constraints in 'toolshed.cabal'.
	* In module "ToolShed.System.File", replaced 'Control.Exception.throw' with 'Control.Exception.throwIO'.
	* Replaced all instances of '(<$>)' with 'fmap' to avoid ambiguity between "Control.Applicative" & "Prelude" which (from 'base-4.8') also exports this symbol.
