v1.0.3: quiet update hint instead of interactive prompt

netsh emits in the OEM code page (CP866 on RU Windows); the modern console showed it as 'DHCP ╤Г╨╢╨╡ ╨▓╨║╨╗╤О╤З╨╡╨╜╨╛...'. Our own English Setting/Done lines remain, and Get-NetIPAddress already prints proper Unicode.

 ## [Unreleased]
 
+## [1.0.3] - 2026-05-17
+### Changed
+- Update check no longer interrupts startup with an interactive prompt. If a newer release is available, a quiet right-aligned `update available (vX.Y.Z)` hint is printed in dim grey directly under the banner — no key press required.
+
+## [1.0.2] - 2026-05-17
+### Fixed
+- Suppress `netsh` output to avoid mojibake on non-UTF-8 consoles (Russian Windows printed `╤Г╨╢╨╡ ╨▓╨║╨╗╤О╤З╨╡╨╜╨╛...` because netsh emits in the OEM code page). Our own English status lines remain; the post-change `Get-NetIPAddress` block already prints Unicode.
