gatbxr 0.2.0 (2026-11-13)

Credited the authors and copyright holders of the original Sheffield 'MATLAB' toolbox in Authors@R.
Changed the license to GPL (>= 2), as required for a derived work of the GPL-licensed original toolbox.
Revised Title and Description following CRAN review.

xovmp() and all xov*() crossover functions: the crossover probability Px was inverted (pairs were crossed when they should not be), and the single-point cut was always placed after the first locus.
recmut(): the second offspring of each pair now moves in the opposite direction (-Diff) as in the original toolbox, and identical parent norms no longer cause division by zero.
bs2rv(): fixed decoding when lbin = FALSE; lb, ub, code, scale, lbin and ubin may now be given per variable.
crtbp(): fixed argument handling when Lind contains a base vector, and added informative errors for unsupported argument combinations.
ranking(): individuals with equal objective values now receive the same (average) fitness; RFun = NULL now works as documented.
migrate(), mutate() and select() failed with their default arguments on R >= 4.2.0.
reins(): InsOpt of length 1 now works as documented.
scaling(): no longer returns NaN when all objective values are equal.
