Release 1.16.1

Security

• The host detector ran ioreg, kenv and powershell.exe through a shell, so they were
  looked up on PATH, and on Windows in the current directory. A program placed there ran
  instead. It runs /usr/sbin/ioreg, /bin/kenv and reg.exe by absolute path, without a
  shell (GHSA-fc6f-cp96-6g5w).
• When the host id lookup failed, host.id was "" on macOS and Windows, or /bin/kenv on
  BSD. It is left out instead (GHSA-fc6f-cp96-6g5w).
