Update to version 0.9.9:

============================================================================
RELEASE CANDIDATE 0.9.9 : Minor portability fixes

# NetBSD 4 build fixes.

============================================================================
RELEASE CANDIDATE 0.9.8 : Major feature enhancements, major security fixes

# Support interacting with Teredo clients behind symmetric NATs.
# 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 0.9.7 : Major security fixes

# Fix infinite UDP packet forwarding loop in Teredo server (MTFL-SA 0603).

=============================================================================
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).

=============================================================================
BETA RELEASE 0.9.4 : Major features enhancement

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

=============================================================================
BETA RELEASE 0.9.3 : Major features enhancement, major bug fixes

# Use dedicated thread for packets transmission and reception. Miredo
  should now leverage dual-process, dual-core and SMT systems.

# 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.
# Drop incoming multicast traffic as a precautionary measure.
# Truncate PID file properly when updating it.
# Fix deadlocks and spurious exits upon some signals (such as SIGCONT).
# Fix deadlock when Teredo server DNS hostname resolution fails.
# Handle would-be “spurious wakeups” properly.
# Fix IPv4 global unicast access-list.
# Fix SO_REUSEADDR socket option usage.
# Use C99 restrict keyword at sensible places for compiler optimization.
# Portability fixes for DragonFly BSD.
# Work-around for some uClibc POSIX defines insanity.
# Got rid of all C++ code.
# Renamed libteredo-mire to teredo-mire for consistency.
# Leverage newer autoconf macros.
# Fix encoding of non-ASCII characters in manual pages.
# Work-around for platforms that can't rename tunnel network interface.
# Build libmiredo dynamically to reduce global code size.
# Fix inclusion of non-PIC code into shared libraries.

(Unstable version 0.9.3 includes all fixes from stable version 0.8.5)

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)
