A new snapshot, `0.0.20171011`, 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 ==

  * receive: do not consider 0 jiffies as being set
  This should fix some issues on 32-bit platforms with sending cookie reply
  messages when they're not required.
  * socket: compare while unlocked first
  * socket: don't bother recomparing afterwards
  * socket: gcc inlining makes this faster
  We no longer take a lock when updating the endpoint, which should yield
  some performance benefits.
  * tools: try again if dump is interrupted
  The tools will now try again to get information about a device if somebody
  tries to modify the device while a dump is occurring.
  * Makefile: quiet recursive make
  Our makefile produces slightly slicker output now.
  * qemu: bump stable kernel
  Usual test suite house maintenance.
  * crypto/x86_64: satisfy stack validation 2.0
  The kernel's new objtool used to warn on some things in our AVX
  implementations, especially code generated from qhasm which uses its own
  stack layout. This commit works around it to squelch warnings.
  * routingtable: only use device's mutex, not a special rt one
  * routingtable: iterate progressively
  * tools: store tail pointer to make coalescing peers fast
  We replace the Netlink algorithms for grabbing the allowed IPs, so
  that they're now O(n) instead of O(n^2).
  * tools: warn once on unrecognized items
  This follows this LKML discussion:
  * compat: move version logic to compat.h and out of main .c
  * contrib: filter compat lines
  Should make it easier to produce a compat-free WireGuard tree.
  * send: do not requeue if packet is dead
  * socket: set skb->mark in addition to flowi
  Mangle tables now work with wg-quick.
  * tools: man: include kill-switch documentation using fwmark
  iptables -I OUTPUT ! -o %i -m mark ! --mark $(wg show %i fwmark) -j REJECT
  * receive: disable bh before using stats seq lock
  This avoids a potential deadlock with interrupts and the stats counters.
