package digestif

• Use CAMLextern rather than extern in caml_* forward declarations to support bytecode linking on Windows (@jonahbeckford, #157)
• Add x-maintenance-intent into OPAM file (@hannesm, #158)
• Implement feedable hmac (@reynir, #155)

v1.2.0 2024-03-18 Paris (France)

• Fix threads support (@dinosaure, #140)
• Delete the META trick needed for MirageOS 3 when we install digestif (@dinosaure, #141) This version of digestif breaks the compatibility with MirageOS 3 and ocaml-freestanding. This PR should unlock the ability to use dune-cache.

v1.1.2 2022-04-08 Paris (France)

• Minor update on the README.md (@punchagan, #133)
• Support only OCaml >= 4.08, update with ocamlformat.0.21.0 and remove bigarray-compat dependency (@hannesm, #134)

• Hide C functions (sha3_keccakf) (@hannesm, #125)
• Use ocaml to run install.ml instead of a shebang (@Nymphium, #127)
• Use command -v instead of which (@Numphium, #126)
• Add @since meta-data in documentation (@c-cube, @dinosaure, #128)
• Update the README.md (@dinosaure, @mimoo, #130)

v1.0.1 2020-02-08 Paris (France)

• Fix esy support (@dinosaure, #115)
• Fix big-endian support (@dinosaure, #113)

v1.0.0 2020-11-02 Paris (France)

• breaking changes Upgrade the library with MirageOS 3.9 (new layout of artifacts) Add tests about compilation of unikernels (execution and link) (#105, @dinosaure, @hannesm)
• Fix esy installation (#104, @dinosaure)
• breaking changes Better GADT (#103, @dinosaure) As far as I can tell, nobody really use this part of digestif. The idea is to provide a GADT which contains the type of the hash. From third-part libraries point-of-view, it's better to pattern-match with such information instead to use a polymorphic variant (as before).
• breaking changes key used for HMAC is a constant string (#101, @dinosaure, @hannesm) The key should not follow the same type as the digest value (string, bytes, bigstring). This update restricts the user to user only constant key (as a string).

v0.6.1 2018-07-24 Paris (France)

• move to jbuilder/dune

v0.6 2018-07-05 Paris (France)
