V9x Remote Agent v0.13.1

0.13.1 (2026-10-24)

Added

• Unattended self-update for hosts. SETUP.EXE /update /S runs the
  same check, signature, version and SHA-256 checks as /update, with no
  windows or questions and never a reboot, so a host can trigger it over
  EXEC (V9 Retro Controller does, from the update server directly). The
  installed copy waits for its child, so the exit code is the result: 0
  staged, 1 failed, 3 nothing newer or nothing published. The outcome is
  also written to C:\V9XREMOTE\TEMP\UPDATE.INI ([result] status=
  staged/current/none/failed, installed=, latest=, message=). A staged
  update is the usual V9XNEW.EXE / V9XSNEW.EXE, so the host can apply it
  at once with UPDATE_REQUEST instead of waiting for a restart.

Changed

• SETUP.EXE /update without /S is unchanged, except that "nothing newer"
  still exits 1 there (3 is the unattended mode's code).
