Hello,

A new snapshot, `0.0.20190601`, 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 constitute 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 relevant changes.

== Changes ==

  * compat: don't call xgetbv on cpus with no XSAVE
  
  There was an issue with the backport compat layer in yesterday's snapshot,
  causing issues on certain (mostly Atom) Intel chips on kernels older than
  4.2, due to the use of xgetbv without checking cpu flags for xsave support.
  This manifested itself simply at module load time. Indeed it's somewhat tricky
  to support 33 different kernel versions (3.10+), plus weird distro
  frankenkernels.
