Switch to bytes-based implementation. This is simpler and faster (up to 30% faster). Bitv_string is still there but deprecated (now identical to Bitv).
Functions to_int... do not fail anymore when bit vectors are small (and behave as if high bits are zero).
New function tanimoto (Tanimoto score) (contribution by François Berenger)
1.6 (06/02/2021)
fixed build on 32-bit platforms e.g. js_of_ocaml (patch from Tim Bourke)
added exceeds_max_length to replace max_length (deprecated)
1.5 (30/01/2021)
new functions rotatel and rotater (patch from Tim Bourke)
1.4 (02/08/2020)
switch to dune build system, and opam 2.0
add to/of_bytes for machine-independant serialisation
fix binary serialisation when vector is larger than 2^32
1.3 (14/12/2017)
fix compilation for OCaml 4.06 (safe-string)
1.2 (10/02/2017)
added pop (population count, i.e., number of 1 bits)
suppressed some warnings with OCaml >= 4.00
1.1 (10/04/2013)
installation using ocamlfind (if found) or in ocamlc -where/bitv otherwise
fixed of_int64_(u)s on a 32-bit architecture (thanks to Florent Monnier)
1.0 (14/08/2012)
functions to/of_int64_s
new functions output_bin/input_bin for export/import in a machine-independent way (contribution from Bruno Guillaume)
fixed installation (patch from Bruno Guillaume)
0.9 (20/06/2012)
fixed tarball (test.ml was missing)
patched installation to use $(DESTDIR), if any (patch from Bruno Guillaume)
0.8 (28/02/2012)
two different modules L and M for conversions to and from string (least and most significant bits first, respectively); apologies for API incompatibility
improved implementation of iteri_true
0.7 (03/04/2008)
fixed bug with unsafe_blit when len=0 (could affect blit, sub, append, concat and fill when used with 0-length bit vectors), thanks to Pat Rondon
0.6 (18/02/2005)
added iteri_true
added foldi_left and foldi_right
patch for ocaml >= 3.08 (0xffffffff is no more accepted as a literal)
fixed Invalid_argument messages (now exactly the function name)
0.5 (22/11/2002)
added print : formatter -> t -> unit
from_list now fails on negative indexes (patch from Karl Zilles)
from_list_with_length to specify the length (patch from Karl Zilles)
0.4 (29/8/2002)
to_list/from_list to convert to/from lists of integers
added gray_iter to iterate over all bit vectors of length n
configuration with autoconf
0.3 (31/5/2000)
fixed bug in bw_not thanks to Damir Jamsek
0.2 (24/4/2000)
normalization, so that generic equality can be used
efficient implementations of append, sub, blit, concat and fill
