v0.7.0.0

• Added examples to the documentation of built-in functions and particles.
• Fixed some errors in the documentation.
• Fixed a bug in \binomial. Now it returns 0 when the second argument is negative.
• Fixed a bug in \factor. In earlier versions, it may return incorrect results.
• New particles: \concatMap, \fixedPoint, \onAny, \unconcatMap.

Breaking changes

• Some modules in the library are no longer exposed.
• The built-in function \normalForm is removed, because it is never used, and its semantics are not well-defined.
• The result of \divisors is now sorted.
• \intersect and \union are now multiset intersection and union.
• \bifurcate now works on numbers. If the input is a number, it is converted to the range from 0 to the number - 1.

v0.6.1.0

• Now the REPL saves the history to a file named .history in the current directory.
• New built-in functions: \isLong, \sumEach.

Breaking changes

• \charToInt now leaves the argument unchanged if it is already an integer. It still fails if the argument is a non-integral number.
• \intToChar now leaves the argument unchanged if it is already a character.

v0.6.0.0

• Updated some dependencies. Now Nekomata can be built with GHC 9.8.1.
• Fixed a bug in printing truncated results.
• Now characters are internally represented as Word8s instead of Chars.
• Added a REPL command \Arity to print the arity of a function.
• New built-in functions: elem, \filterBy, \minValue, \minMax, \maxValue, \ordering, \pad, \slices.

Breaking changes

• \apply2 is renamed to \onBoth.
• \interval can now take two chars as arguments.
• \intersect, \union and \setMinus now convert numbers and characters to singleton lists.
• Fixed a bug in comparing characters. Now characters are compared by their code points in Nekomata's custom code page instead of Unicode.

Version 0.5.1.0

• New built-in functions: \bifurcate, \divMod, \flatten, \histogram, \isBig, \isSmall, \over, \popCount, \rle, \unrle.
• New particle: \zipWithTrunc.

Breaking changes

• \nonzero is renamed to \isNonzero.
• \nonempty is renamed to \isNonempty.

Version 0.5.0.0

• The interpreter can now limit the number of results to show using the -l option.
• New built-in functions: \bitAnd, \bitOr, \bitXor, \fromBinary, \gt, \lt.

Breaking changes

• The dependency on base becomes base >=4.15 && <5. Now GHC 9.0.1 or newer is required to build Nekomata.
• The string type is removed, and a new character type is added. Now strings are represented as lists of characters. Many built-in functions are changed accordingly.
• \join and concat no longer convert their arguments to strings. Now they convert numbers and characters to singleton lists.
• Many numeric functions now convert chars to their code points before operating on them.
• \range0 now generates a range from 0 to ceil(n)-1 instead of floor(n)-1.
• \join, \concat, \cons and \snoc are now lazier. Joining a non-failing list with a failing list no longer fails immediately. Instead, it only fails when the failing part is actually used. \concat can now concatenate an infinite list of lists.
• \uninterleave is now lazier. It can now uninterleave an infinite list.

Version 0.4.1.0

• New built-in functions: \fromDigits, \interval, \read, \show, \tuple.
• New particle: \fold1.

Version 0.4.0.0

• The language is still incomplete. The code page isn't filled yet. Everything is subject to change.
• New built-in function: \absDiff, \count, \digits, \div2, \divisors, \interleave, \isNonnegative, \isUnique, \mod2, \mul2, \powOf2.
• New particle: \firstInt.

Breaking changes

• Some list functions are now overloaded to work on numbers. When they are used on numbers, they are applied to the range from 0 to the number - 1. These functions are: \anyOf, \uninterleave, \extract, \permutation, \prefix, \reverse, \rotate, \setPartition, \split, \subsequence, \subset, \suffix, \unconcat.
• \convolve now supports arbitrary-dimensional nested lists. Numbers are treated as 0-dimensional nested lists.
• \mapFirst is renamed to \mapWith.
• \deinterleave is renamed to \uninterleave.

Version 0.3.5.0

• New built-in functions: \deinterleave, \longest, \maximumBy, \minimumBy, \orNeg, \shortest, \unitVec2D.
• New particle: \lengthWhile.

Breaking changes

• \toBase2Rev is renamed to \binary.

Version 0.3.4.0

• New built-in functions: \andThen, \chunks, \convolve, \extract, \half, \isZero, \toBase2Rev.
• New particle: \filter.

Breaking changes

• The code page is updated. The character ∞ is replaced with ½, and the character ∂ is replaced with ¿.

Version 0.3.3.0

• New built-in functions: \factor, \index, \intersect, \rot3, \tally, \union.
• New particle: \dupDip2.
