package bitv

2.0

• 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

• documentation using ocamlweb

• to_string, from_string

• bitwise operations, all_zeros

0.1

• first release
