Hello,

A new version, v1.0.20200820, of wireguard-tools has been tagged in the git
repository, containing various required userspace utilities, such as the
wg(8) and wg-quick(8) commands and documentation.

== Changes ==

  * ipc: split into separate files per-platform
  
  This is in preparation for FreeBSD support, which I had hoped to have this
  release, but we're still waiting on some tooling fixes, so hopefully next
  wg(8) will support that. Either way, the code base is now a lot more amenable
  to adding more kernel platform support.
  
  * wincompat: fold random into genkey
  
  As part of moving to per-platform files, we can fold our get_random_bytes
  implementation in the same way that we handle the other ones.
  
  * systemd: add reload target to systemd unit
  
  Users can now run `systemctl reload wg-quick at wgnet0`, as described in the
  wg-quick(8) man page. Note that this won't adjust Address=, DNS=, or the
  various other non-wg(8) fields.
  
  * man: wg-quick: use syncconf instead of addconf for strip example
  
  Simple documentation fix.
  
  * pubkey: isblank is a subset of isspace
  * ctype: use non-locale-specific ctype.h
  
  In addition to ensuring that isalpha() and such isn't locale-specific, we also
  make these constant time, even though we're never distinguishing between bits
  of a secret using them. From that perspective, though, this is markedly better
  than the locale-specific table lookups in glibc, even though base64 characters
  span two cache lines and valid private keys must hit both. This may be useful
  for other projects too: https://git.zx2c4.com/wireguard-tools/tree/src/ctype.h
  
  * wg-quick: wait on process substitutions
  
  Bash does not propagate error values, which is a bummer, but process
  substitutions are a useful feature. Introduce a new idiom to deal with
  this: either "; wait $!" after the line to propagate the error, or "||
  true" to indicate explicitly that we don't care about the error. Discussions
  about this with upstream bash didn't lead anywhere:
  https://lists.gnu.org/archive/html/bug-bash/2020-08/msg00031.html
  So, we now work around this limitation manually.
