        CHANGES IN bit VERSION 4.0.0

NEW FEATURES

    o new superclass ?booltype now allows proper method
      dispatch even for two user defined booleans, e.g. (bit | bitwhich)
    o new ordinal 'booltypes' nobool < logical < bit < bitwhich < \ 
which < ri
      and diagnostic functions booltype() and is.booltype()
    o bitwhich now has methods for [[ [ [[<- and [<-
    o new functions 'c', '==', '!=', '|', '&', 'xor' for .booltype
    o new function bitwhich_representation() to inspect the bitwhich
      representation without the cost of unclass()
    o new method 'is' for .which, .ri, .hi (and .booltype)
    o new coercion generic as.booltype with .default method
    o new coercion method as.logical.which
    o new generic as.ri with methods for .ri and .default (lossy)
    o new methods rep, rev, as.character and str for .bit and .bitwhich
    o new methods all, any, min, max, range, sum, summary for .booltype, .which
    o new method anyNA for all booltypes
    o new dummy method 'is.na' for .bit, .bitwhich
    o new function in.bitwhich much faster than %in%
    o new integer sorting function bitsort() using bit_sort() or bit_sort_unique()
      which can be by an order of magnitude faster than radix sorts
      or falling back to one of countsort(), quicksort2(), quicksort3()
    o new symmetric set function symdiff
    o new functions copy(), reverse() for copying and reversing integer vectors
    o new helper functions range_na(), range_nanozero(), range_sortna()
      join multiple tasks in one go
    o new fast unary functions for integers: bit_unique, bit_duplicated,
      bit_anyDuplicated, bit_sumDuplicated
    o new fast binary functions for integers: bit_in, bit_intersect, bit_union,
      bit_setequal, bit_symdiff, bit_setdiff, bit_rangediff
    o new fast unary functions for sorted integers: merge_rev,
      merge_unique, merge_duplicated, merge_anyDuplicated, merge_sumDuplicated,
      merge_first, merge_last,
    o new fast binary functions for sorted integers:
      merge_firstin, merge_firstnotin, merge_lastin, merge_lastnotin,
      merge_match, merge_in, merge_notin,
      merge_union, merge_intersect, merge_setdiff, merge_symdiff,
      merge_setequal
    o new even faster binary functions when the first argument is a range of \ 
integers:
      merge_rangein, merge_rangenotin, merge_rangesect, merge_rangediff
    o new function firstNA substantially faster than which.max(is.na(x))
    o new function getsetattr() does setattr() but returns the old attr()
    o new function get_length() directly returns LENGTH(SEXP)
      circumventing all method dispatch for length()
    o new methods rlepack.integer, rleunpack.rlepack anyDuplicated.rlepack

USER VISIBLE CHANGES

    o license has been extendend from GPL-2 to GPL-2 | GPL-3
    o S3methods are no longer exported in NAMESPACE
      (except for .booltype)
    o class bitwhich
    - now is a fully functional alternative to bit vectors
    - has argument order changed to (maxindex, x, poslength)
    - its internal representation of bitwhich(0) has been changed
      from FALSE to logical() and from unsorted to sorted integers
    o class 'which' now carries an attribute 'maxindex' if available
    o as.which() and bitwhich() now filter zeroes and store data unique(sort(x))
    o as.which() now has methods for .which, .logical, .integer and .numeric
      instead of .default.
    o bit() and bitwhich() now behave more like logical(), without
      arguments they return objects of length zero
    o as.bit, as.bitwhich and as.which now have methods for class NULL
      such that for example as.bit(c()) will return bit(0)
      (wish of Martijn Schuemle)
    o binary operators now allow for different lengths
      and recycle instead of throwing an error
    o xor.default now keeps the original definition of xor() and uses
      a new method xor.logical to speed-up logicals
    o the generics poslength and maxindex have been moved from package ff
      with methods now for .default, .logical, .bit, .bitwhich, .which, .ri
    o old method chunk.default has been renamed to chunks and now returns with names
      (for backward compatibility chunk() with named arguments behaves as before)
    o new method chunk.default calls chunks() along the length(x)
      using typeof(x) or vmode(x), this replaces chunk.bit from package ff
    o clone.default now uses R's C-function duplicate()
      and clone.list has been removed
    o intisasc() and intisdesc() have a new argument
      na.method=c("none","break","skip") to \ 
specify tie handling

TESTING and DOCUMENTATION

    o there are much more regression tests now
    o testing uses package testthat
    o documentation uses package roxygen2 now
    o new vignettes bit-demo, bit-usage and bit-performance

BUG FIXES

    o assignment functions '[<-.bit' now behave like '[<-.logical' when it
      comes to NAs or ZEROs in subscripts
    o length<-.bit no longer tries to access memory before it is allocated
    o as.bit.bitwhich now handles non-positive bitwhich correctly
    o declare as static many functions/variables in bit.c. (Thanks to Brian Ripley)
