Hello,

A new snapshot, `0.0.20180718`, 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 ==

  * tools: only error on wg show if all interfaces fail
  
  wg(8) now has a more reasonable error code semantic.
  
  * receive: account for zero or negative budget
  
  A correctness fix that no other drivers implement but that we really should
  be doing anyway.
  
  * recieve: disable NAPI busy polling
  
  This avoids adding one reference per peer to the napi_hash hashtable, as
  normally done by netif_napi_add(). Since we potentially could have up to
  2^20 peers this would make busy polling very slow globally. This approach is
  preferable to having only a single napi struct because we get one gro_list
  per peer, which means packets can be combined nicely even if we have a large
  number of peers. This is also done by gro_cells_init() in net/core/gro_cells.c.
  
  * receive: use gro call instead of plain call
  
  This enables incredible performance improvements in some cases. Benchmark and
  see for yourself. It should affect large TCP flows.
  
  * wg-quick: allow link local default gateway
  
  IPv6 endpoints will now work better on BSD and Darwin.
  
  * device: destroy workqueue before freeing queue
  
  Another small correctness fix.
