Fix regression on adler32 (the OCaml version) introduced by #76 and spotted by @balat (@dinosaure, #80). We advise the user to upgrade as soon as he/she can checkseum. checkseum.0.5.0 will be disabled with this release.
Fix the CI on Windows (@dinosaure, @MisterDA, #79) See (mirage/bechamel#41 for more details)

Add the support of Esperanto (@dinosaure, #69)

Use canonical _WIN32 macro to detect Windows (@jonahbeckford, #61)
Fix Windows support with cygpath (@MisterDA, #60)
Use ocaml variable to execute install.ml instead of a shebang with env (@vapourismo, @dinosaure, #62)
Upgrade to ocamlformat.0.21.0 (@hannesm, #63)
Remove bigarray-compat package (@hannesm, #63)
Support only OCaml >= 4.07 (@hannesm, #63)
Optimize checkseum.c and use the advantage of [@untagged] and [@unboxed] checkseum requires optint.0.2.0 now (@dinosaure, #64)
Update the README.md (@dinosaure, #65)
Use caml_copy_int32 instead of copy_int32 (@dinosaure, #66)

freenstanding support does not need opam (@sternenseemann, @dinosaure, #53)
Fix big-endian support (@dinosaure, #56)
Use which when command -v is not available (@dinosaure, @sternenseemann, @mseri, #56)
Fix esy support and on its environment the MirageOS 3 support (@dinosaure, @mseri, #56)
Upgrade to ocamlformat.0.19.0 (@dinosaure, #57)

fix cross-compilation with dune -x windows (#45, @dinosaure, @pirbo)
add CRC-24 (#43, @dinosaure, @cfcs)
factorize C stubs (as digestif)
avoid clash of names when we use checkseum.c Any functions are prefixed by checkseum_
fix META file (#39 & #41, @hannesm, @dinosaure) A test was added to see if runes (static C libraries) are available for MirageOS targets (freestanding & xen)
provide a binary checkseum to digest standard input or file checkseum.checkseum is available to compute check-sum of standard input or file. The tool is used only for debugging.
clean distribution (#38, @dinosaure) checkseum depends only on bigarray-compat, base-bytes & optint
limits.h is available on any targets (#37, @dinosaure, @pirbo)

Compatibility with mirage+dune (#29, @dinosaure)
Use bigarray-compat (#29, @TheLortex)
Add constraints with < mirage-runtime.4.0.0
checkseum (as some others packages) must be used with MirageOS 4 where checkseum.0.9.0 is a compatibility package with Mirage)S 3
Replace STDC macro check by STDDEF_H_ to be able to compile (#34, @dinosaure) checkseum with +32bit compiler variant (#34, @dinosaure)
Use a much more simpler implementation of CRC32C to be compatible with large set of targets (#34, @dinosaure)
Avoid fancy operators in OCaml implementation of CRC32 and CRC32C (#34, @dinosaure)
Require optint.0.0.3 at least (#34, @dinosaure)

Use experimental feature of variants with dune (#25, @dinosaure, review @rgrinberg) checkseum requires at least dune.1.9.2
Add conflict with < mirage-xen-posix.3.1.0 packages (#21, @hannesm)
Provide unsafe_* functions (@dinosaure)
Re-organize C implementation as digestif (@dinosaure)
Remove #include <stdio.h> in C implementation (@dinosaure)
Avoid partial application of functions, optimization (#19, @dinosaure)
Add ocamlformat support (@dinosaure)
cross-compilation adjustement about MirageOS backends (#18, @hannesm)
