8.0.1

CHANGES:

• TCP: add src : flow -> ipaddr * int, implemented by getsockname on unix
  (#511 @hannesm)
• TCP unix stack: increase TCP buffer size (was 4096, is now 65536)
  (#510 @edwintorok)
• TCP: adapt to mirage-flow 4.0:
  add val shutdown : flow -> [ `read | `write | `read_write ] -> unit Lwt.t
  (#512 @hannesm, review by @djs55)

8.0.0

CHANGES:

• TCP: add ID for PCB for connection tracking (#495 @TheLortex)

• Unix stack, UDP: copy buffer before passing it to client (#502 @reynir)

• API renamings (due to ppx_cstruct removal): accessors such as
  Icmpv4_wire.get_icmpv4_ty are now Icmpv4_wire.get_ty ("_icmpv4" is removed)
  (#505)

• Use Cstruct.to_string instead of deprecated Cstruct.copy (#506 @hannesm)

• Remove ppx_cstruct dependency (#505 @hannesm)

• Remove mirage-profile dependency (#504 @hannesm)

• opam: add lower bounds for cmdliner and alcotest (#506 @hannesm)

7.1.2

CHANGES:

• TCP: fix memory leaks on connection close in three scenarios (#489 @TheLortex)
  • simultanous close: set up the timewait timer in the Closing(1) - Recv_ack(2) -> Time_wait
    state transition
  • client sends a RST instead of a FIN: enable sending a challenge ACK even when the reception
    thread is stopped
  • client doesn't ACK server's FIN: enable the retransmit timer in the Closing(_) state

7.1.1

CHANGES:

• Ndpv6: demote more logs to debug level (#480 @reynir)
• Ndpv6: set RS opt header (#482 @reynir)

• Improve log messages of connect and disconnect of various layers and stacks:
  separate IP addresses with ", " (#485 @hannesm)
• TCP log sources: prefix "tcp" to distinguish them (#484 @reynir)

7.0.1

CHANGES:

• Fix cancelation of Unix socket when we don't use Stack.connect (@dinosaure, @hannesm, #466)

7.0.0

CHANGES:

• Fix memory leak in processing RST packets (#460 @balrajsingh, reported in
  #456 by @dinosaure)
• Move module types (IP, UDP, TCP, STACK, ICMP) into tcpip core library
  (#463 @hannesm)

6.4.0

CHANGES:

• Adapt to mirage-protocols 6.0.0 API (#457 @hannesm)
• TCP and UDP now have a listen and unlisten function (fixes #452)
• type ipinput (in TCP and UDP) and listener (in TCP) have been removed

6.3.0

CHANGES:

• Use Cstruct.length instead of deprecated Cstruct.len (#454 @hannesm)
• Avoid deprecated Fmt functions (#455 @hannesm)

v6.2.0

CHANGES:

• This allows to listen on the same port as sending via UDP in the dual socket
  stack, and avoids file descriptor leaks in the socket stack.
• Socket stack: avoid file descriptor leaks (remember opened file descriptors in
  data structure, close them in disconnect)
  (#449 @reynir @hannesm, fixes #446 #450)
• Socket stack: convert an incoming packet on a dual socket to v4 source IP if
  received via IPv4 (#451 @reynir @hannesm)
• Allow freestanding compilation without opam (#447 @sternenseemann)
• Adapt to alcotest 1.4.0 breaking change (#448 @craigfe)
