-## [1.2.0] - 2026-05-18
-### Changed
-- **Rewrote netswitch in Python** (was PowerShell + ps2exe). The single-file `.ps1` script is gone, replaced by a small `netswitch/` package (`app.py`, `config.py`, `i18n.py`, `network.py`, `platform_win.py`, `update_check.py`) that mirrors the layout used by `dhcpsrv`. CI now builds via PyInstaller instead of ps2exe.
-- Output is now a Rich-styled console (coloured banner, current-config table) instead of plain `Write-Host`.
-- The `Update available (vX.Y.Z)` notice in the header is a clickable terminal hyperlink to the GitHub releases page (OSC 8). Modern terminals render it as a link; older consoles show plain text.
-### Removed
-- `src/netswitch.ps1` and the ps2exe build step. If you specifically need a tiny PowerShell version, check out tag `v1.1.0`.
-
 ## [1.1.0] - 2026-05-18
 ### Added
 - Russian UI translation. On first launch the application asks which language to use (`1) English`, `2) Русский`) and writes the answer to a fresh `config.ini` next to `netswitch.exe`. To change the language later, edit `language = en` / `language = ru` in that file — the comment at the top of the file explains how, in both languages.
