Hello,

A new snapshot, `0.0.20161216`, has been tagged in the git repository.

Please note that this snapshot is, like the rest of the project at this point
in time, experimental, and does not consitute a real release that would be
considered secure and bug-free. WireGuard is generally thought to be fairly
stable, and most likely will not crash your computer (though it may).
However, as this is a pre-release snapshot, it comes with no guarantees, and
its security is not yet to be depended on; it is not applicable for CVEs.

With all that said, if you'd like to test this snapshot out, there are a
few relevent changes.

== Changes ==

  * messages: increase header by 3 bytes for alignment
  
  PACKAGERS PLEASE UPDATE, as this is a protocol-breaking change.
  
  * device: disable ipv6 auto address generation
  
  Now finally we have working tcpdump and no useless automatic IPv6 addresses.
  
  * device: rc -> ret
  * device: dellink is already implictly unregister_netdevice_queue
  * device: simplify device_init, since it only returns -EEXIST
  * main: consistent lines
  * device: clean up xmit error path
  * device: allocate tstats in newlink
  * global: move to consistent use of uN instead of uintN_t for kernel code
  * crypto: use kernel's bitops functions
  * messages: remove unused constants
  * blake2s: move self tests to correct directory
  * tools: fix latest-handshake typo in documentation
  * noise: update comments
  * config: cleanups
  * types: enforce consistency
  
  Numerous code quality cleanups.
  
  * device: ensure icmp skb length check is done for v6
  * receive: simplify ip header checking logic
  
  This adds a missing length check and generally simplifies length checks
  throughout.
  
  * peer: don't use sockaddr_storage to reduce memory usage
  
  Now that we have struct endpoint, ditching sockaddr_storage is a no-brainer.
  It has the affect of making parallel decryption faster because it requires
  less of an allocation for the ctx, and thus our kmemcache can be merged.
  
  * tests: avoid non-strict writes via printf
  
  Finally fixing this silly old bug.
  
  * ratelimiter: drop family from action for 4.10
  
  We're getting ready for the first rc of Linux 4.10.
  
  * siphash: update against upstream submission
  
  I've been preparing a big patch for upstream Linux to include SipHash, and in
  the process I improved the implementation considerably.
  
  * hashtables: use counter and int to ensure forward progress
  
  This gives the best of both worlds between the two hashtable rng designs.
