v5.3.1 (2022-07-04)

• Remove stdlib-shims dependency, require OCaml 4.08+ (@hannesm, #112)

• Switch to ounit2 (@Alessandro-Barbieri, #111)

v5.3.0 (2022-03-04)

• Add with_port_of_string function (@dinosaure, @hannesm, #108)

• breaking-change Be restrictive on Ipaddr.of_string (@dinosaure, @hannesm, #109)
  Before this release, Ipaddr.of_string accepts remaining bytes and returns
  a valid value such as "127.0.0.1aaaa" is valid. Now, ipaddr does not
  accept a string with remaining bytes.

v5.2.0 (2021-09-11)

• Use Cstruct.length instead of deprecated Cstruct.len (#106, @hannesm)

• Provide instantiated functors Set, Map, V4.Set, V4.Map, V6.Set, V6.Map
  (#106, @hannesm)

v5.1.0 (2021-06-08)

• Reject octal notation in IPv4 (cve-2021-29921, #104, @jsachs)

• CI fixes, upgrade to ocamlformat 0.18 (@hannesm)

v5.0.1 (2020-09-30)

• Fix V4.Prefix.broadcast and last with /32 prefixes (#102 @verbosemode)

v5.0.0 (2020-06-16)

• Do not zero out the non-prefix-length part of the address in
  {V4,V6}.Prefix.t (#99 @hannesm)
  Removed {V4,V6}.Prefix.of_address_string{,_exn} and
  {V4,V6}.Prefix.to_address_{string.buffer}

  To port code:

  • if you rely on Prefix.of_string to zero out the non-prefix-length address
    bits, call Prefix.prefix : t -> t subsequently.

  • Prefix.of_address_string{,_exn} can be replaced by
    Prefix.of_string{,_exn}, to retrieve the address use
    Prefix.address : t -> addr.

  • The Prefix.to_address_{string,buffer} can be replaced by
    Prefix.to_{string,buffer}, where Prefix.t already contains the IP
    address to be printed.

  • Instead of passing {V4,V6}.t * {V4,V6}.Prefix.t for an
    address and subnet configuration, {V4,V6}.Prefix.t is sufficient.

• Implement {V4,V6,}.succ, {V4,V6,}.pred, {V4,V6}.Prefix.first, and
  {V4,V6}.Prefix.last functions (#94 @NightBlues)

• Rename Prefix.of_netmask to Prefix.of_netmask_exn with labelled
  arguments (~netmask and ~address), provide Prefix.of_netmask which returns
  a (t, [> `Msg of string ]) result value (#95 @hannesm)

• Fix undefined behaviour of V4.Prefix.mem with a CIDR with prefix length 0
  (#98 @verbosemode)

• Use stdlib-shims to prevent deprecation warnings on OCaml 4.08
  (@avsm)

• Remove unnecessary "sexplib0" dependency (#95 @hannesm)

• Remove "{build}" directive from "dune" dependency (#93 @CraigFe)

v4.0.0 (2019-07-12)

• Rename the to/from_bytes functions to refer to octets
  instead. This distinguishes the meaning of human-readable
  addresses (strings in this library) and byte-packed
  representations(octets in this library) from the OCaml
  bytes type that represents mutable strings.

  Porting code should just be a matter of renaming functions
  such as:

  • Ipaddr.of_bytes becomes Ipaddr.of_octets

  • Macaddr.to_bytes becomes Macaddr.to_octets

• Introduce new write_octets functions that can write
  octet representations of IPv4/v6 into an existing bytestring.

• Use the domain-name library to produce domain names
  from IP addresses.

• Remove the ipaddr.sexp and macaddr.sexp ocamlfind
  subpackages and instead have ipaddr-sexp and macaddr-sexp
  to match the opam package names.

• Add new Ipaddr_cstruct and Macaddr_cstruct libraries
  for conversion to/from cstructs (#36 @nojb @avsm)

v3.1.0 (2019-03-02)

• Do not leak a Not_found exception when parsing [:
  in IPv6 and instead raise Parse_error as other errors
  do (found by fuzz testing in #84 by @dinosaure)

• Install automatic toplevel printers for the Ipaddr
  types via [@@ocaml.toplevel_printer]. This enables
  utop to automatically install the printers (@avsm)

3.0.0 (2019-01-02)

This release features several backwards incompatible changes,
but ones that should increase the portability and robustness
of the library.

• Remove the sexp serialisers from the main interface in favour
  of pp functions. Use the Ipaddr_sexp module if you still
  need a sexp serialiser.

  To use these with ppx-based derivers, simply replace the
  reference to the Ipaddr type definition with Ipaddr_sexp.
  That will import the sexp-conversion functions, and the actual
  type definitions are simply aliases to the corresponding type
  within Ipaddr. For example, you might do:

  type t = {
    ip: Ipaddr_sexp.t;
    mac: Macaddr_sexp.t;
  } [@@deriving sexp]
  

  The actual types of the records will be aliases to the main
  library types, and there will be two new functions available
  as converters. The signature after ppx has run will be:

  type t = {
    ip: Ipaddr.t;
    mac: Macaddr.t;
  }
  val sexp_of_t : t -> Sexplib0.t
  val t_of_sexp : Sexplib0.t -> t
  

• Break out the Macaddr module into a separate opam package so
  that the Ipaddr module can be wrapped. Use the macaddr
  opam library now if you need just the MAC address functionality.

• Replace all the of_string/bytes functions that formerly returned
  option types with the Rresult result types instead. This stops
  the cause of the exception from being swallowed, and the error
  message in the new functions can be displayed usefully.

• In the Ipaddr.V6.to_string and to_buffer functions, remove the
  optional labelled argument v4 and always output v4-mapped strings
  as recommended by RFC5952. (#80 by @hannesm).

• Remove pp_hum which was deprecated in 2.9.0.

• Sexplib0 is now used which is more lightweight tha the full
  Sexplib library. Minimum OCaml version is now 4.04.0+ as a result
  of this dependency.

• Improvements to the ocamldoc formatting strings for better
  layout and odoc compatibility.

2.9.0 (2018-12-11)

• Add pp functions for prettyprinting and deprecate pp_hum variants.
  The two functions are currently the same, so porting is just a matter
  of replacing existing uses of pp_hum with pp (#71 @verbosemode)

• Fix deprecation warnings on newer OCaml standard libraries (#74 @cfcs).

• Fix base-unix depopt to be a real dependency (#68 @rgrinberg).

• Fix missing sexplib dependency (#66 #67 @bmillwood).

• Port to Dune from jbuilder and update opam metadata to 2.0 format (#76 @avsm).

• Remove unused variable and bindings warnings in the implementation and
  signatures (#76 @avsm)

• Fix toplevel handling of the ipaddr.top package by linking
  to compiler-libs instead of compiler-libs.toplevel (#76 @avsm based on
  fix in mirage/ocaml-uri#130 by @yallop)

• Update Travis to test latest distros by using their aliases (#76 @avsm)

• Upgrade opam metadata to the 2.0 format (#76 @avsm)

2.8.0 (2017-06-01)

• Port to Jbuilder (#65 @vbmithr @avsm).
  There should be no observable changes, except that Ipaddr_unix is now
  in a separate subdirectory. This means that packages that implicitly
  depended on the module without including the ocamlfind ipaddr.unix
  package may now fail. Just adding the ocamlfind dependency will fix it,
  and is backwards compatible with older Ipaddr releases.

• Minimum version of OCaml required is now 4.03.0 (formerly was 4.02.2),
  due to the use of recent ppx_sexp_conv with Jbuilder also having that
  as the minimum supported compiler version.

2.7.2 (2017-02-16)
