CHANGES (p.checkseum.0.3.0.doc.CHANGES)

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)
