# Fix compilation on some systems.
# Add simplified Chinese localization.
# Fix compatibility with newer GNU/automake.
# Add systemd configuration file.
# Automatically load if_tun on FreeBSD.
# Use POSIX tree instead of linked list when libJudy is missing/disabled.
# Fix C pointer aliasing violations.
# Fix compilation with FreeBSD 7.2 or later.
* Fix crash in client more (regression from 1.1.6).
* Thread-safety fixes (with regards to sigaction and strerror).
* Incomplete ISATAP support removed.
In the mean time, proper support was added within the Linux kernel.
* Fix server link-local address, compatibility with Vista clients.
* Fix SIGHUP signal handling.
* Fix compiling on MacOS X and/or without libJudy.
* Fix unlikely race condition in Teredo maintenance procedure setup.
* Fix Teredo address randomization (reachability problems).
* Better debug messages.
* Allow GNU General Public License version 3 (and would be later).
* Fix filtering error within miredo-server (regression from 1.1.0).
* Fix fatal padding mistake on old ABI ARM achitecture.
* Remove NAT type determination:
Miredo now runs behind any type of NAT. However, connectivity might
be severely degraded behind the worst devices, such as symmetric NATs.
* Add 12 bits of randomness to Teredo client address:
Teredo addresses are less predictible, which should enhance host
protection against network scanning.
* Remove brittle and battery-unfriendly "autoclient" mode:
Proper default IPv6 source address selection (RFC3484) implementation
would address most of the use cases for this, as well as other issues.
If that is not sufficient, an external connection management system
is anyway needed to start/stop Miredo when appropriate.
* Restore "cone" RelayType:
All relays should use it, as it improves support for some kinds of
(pretty broken but nevertheless deployed) NAT devices.
* Use a hook shell script for client interface configuration.
* Add a bunch of debug messages to debug builds.
* Rewrite clock subsystem to avoid polling when idle (battery savings).

# Fix multiple problems with HMAC/ping authentication of non-Teredo nodes.
# Increase timestamp wrap time from 18 hours to 70 years to avoid replay
attacks against authentication tokens.
# Allow Router Advertisement through the ISATAP tunnel (untested).
isatapd remain very experimental, particular client-side.
Someone ought to make a clean kernel implementation instead.
# Use HMAC instead of random nonces in Teredo clients.
=============================================================================

BETA RELEASE 0.9.6 : Major compatibility fixes
# Lots of portability fixes, mostly for FreeBSD and the likes.
# Removed some dead code.
# Provide teredo-mire by default.
# Print more helpful error message for some common BSD tunneling issues.
=============================================================================
BETA RELEASE 0.9.5 : Major features enhancement, major bug fixes
# Removed too brittle cone NAT support. As a side effect, miredo is much
faster to startup in client mode in most cases.
# Fix server-side handling of Windows Vista client solicitations.
# Removed the IgnoreConeBit configure option. The cone bit is now always
ignored (this was the default ever since the introduction of that option).

# More refined system clock usage brings about 30% performance boost.

# Receive to-be-decapsulated and to-be-encapsulated packets in blocking
mode; this improves performance by about 10% on Linux.
# Use the POSIX monotonic clock for maintenance procedure and “exclusive”
mode watch if POSIX monotonic clock and clock selection are available.
# Minor optimizations to the most stressed code paths.
# Suppress spurious 4-seconds delay when waiting for “symmetric” probes.
# Minimalistic support for ISATAP client in ISATAPd.
# Ignore invalid Router Advertisements properly.

# Work-around for some uClibc POSIX defines insanity.
# Got rid of all C++ code.

BETA RELEASE 0.9.1 : Major features enhancement
# Created and referenced a developper mailing list: <miredo-devel at
remlab.net>. Send a mail with subject “subscribe” to <miredo-devel-request
at remlab.net> to subscribe.
# Added isatap, an ISATAP router based on libtun6 and miredo.
After careful IETF IPR claim check, it seems ISATAP can be freely
implemented anyway.
# Working support for Mac OS X:
- work-around overly long closefrom() replacement,
- work-around tuntap for OS X spurious initialization error.
- add required defines for pthread to work properly.
# Added libteredo-miredo, an undocumented Teredo “test card”.
# Improve miredo-checkconf semantics.
# Multi-threaded libteredo, and finer grained locking.
# Fix initialization in libteredo sometimes causing a crash at startup.
# Fix race condition in libteredo-list unit test.
# Fix _impossible_ overflow of FD_SET().
(Unstable version 0.9.1 includes all fixes from stable version 0.8.4)
"Teredo: Tunneling IPv6 over UDP through NATs" Internet proposed
standard (RFC 4380). It can provide either client or relay
functionality. A separate program, miredo-server is also included in
the package; it consists of a Teredo server.
Miredo can be used to provide IPv6 connectivity to users behind NAT
which do not support IPv6, and not even proto-41 forwarding. For this
to work, users need to have a Teredo client running on their system.
That can be Miredo itself on Linux/FreeBSD/OpenBSD/NetBSD.

Will (maybe) only work on NetBSD-current of an hour ago.
Thanks to Hubert and Amitai for help with this one.
