+# Changelog
+
+All notable changes to **netswitch** are documented in this file.
+
+The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and the project uses [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+## [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.
+- Bilingual `README.ru.md` linked from the main `README.md`.
+
+## [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.
+
+## [1.0.1] - 2026-05-17
+### Changed
+- Dropped the `made by engelgardt` line from the startup banner — keep author credit in the README only.
+### Added
+- Embedded application icon in the exe (via ps2exe `-iconFile assets/icon.ico`).
+
+## [1.0.0] - 2026-05-16
+### Added
+- First public release on GitHub.
+- Portable `.exe` (~30 KB) built from PowerShell via ps2exe.
+- Self-elevation through UAC.
+- Physical wired NIC filter — Wi-Fi, VPN, virtual, Hyper-V, VMware, VirtualBox, TAP/TUN, WireGuard, OpenVPN, Tailscale, ZeroTier, Bluetooth, Loopback and WAN Miniport adapters are hidden from the picker.
+- Two modes: **Static** (default `10.10.10.1/24`, optional gateway) and **DHCP**.
+- Current IPv4 configuration is printed after the change.
+- Auto-update check on startup: polls GitHub `/releases/latest` with a 3-second timeout and offers to open the download page if a newer version exists. Silent on offline / API errors.
+- MIT licensed.

+```
+
+The script self-elevates through UAC if you launched it without admin.
+
+## Build the portable .exe locally
+
+```
+Install-Module ps2exe -Scope CurrentUser
+Invoke-ps2exe -inputFile src/netswitch.ps1 -outputFile netswitch.exe `
+    -title "netswitch" -description "NIC IP/DHCP toggle - made by engelgardt" `
+    -company "engelgardt" -version "1.0.0.0" `
+    -requireAdmin
+```
+
+## Cut a release
+
+1. Update `src/netswitch.ps1` — bump `$NetswitchVersion` to `X.Y.Z`.
+2. Update `CHANGELOG.md` — move items from `[Unreleased]` into a new `[X.Y.Z]` section with today's date.
+3. Commit: `git commit -am "vX.Y.Z: …"`.
+4. Tag: `git tag vX.Y.Z`.
+5. Push: `git push && git push --tags`.
+
+GitHub Actions picks up the tag, builds the exe via ps2exe, writes the SHA-256, and creates the GitHub Release with the zip attached.
+
+## Where features go
+
+The whole tool is a single PowerShell file with these sections (in order):
+
+1. `$NetswitchVersion` / `$GithubRepo` — top of file.
+2. **Self-elevate** block — UAC if non-admin.
+3. **Banner** — Write-Host title.
+4. **`Test-NetswitchUpdate`** — GitHub /releases/latest poll.
+5. **Adapter filter + picker** — `$skipDescriptionPattern`, `$skipMediaTypes`, `Get-NetAdapter | Where-Object {...}`.
+6. **Mode prompt** — Static / DHCP.
+7. **Static branch** — `netsh interface ipv4 set address ... static ...`.
+8. **DHCP branch** — `netsh interface ipv4 set address ... source=dhcp`.
+9. **Current config display** — `Get-NetIPAddress | Format-Table`.
+
+If a section grows past ~50 lines, factor it into `src/lib/<thing>.ps1` and dot-source it from the main file.

 A tiny portable tool to flip a Windows network adapter between a **static IP** and **DHCP** with a few keystrokes.

 Built for the recurring engineer chore of "give my laptop NIC 10.10.10.1 so I can talk to a server's BMC" and "now put it back on DHCP so I can have internet again."

+
+[🇬🇧 English](README.md) | 🇷🇺 На русском
+
+Маленький портативный инструмент, который за пару нажатий переключает сетевой адаптер Windows между **статическим IP** и **DHCP**.
+
+Решает регулярную задачу инженера: «дай моему ноуту 10.10.10.1, чтобы я мог достучаться до BMC сервера», а потом «верни обратно на DHCP, чтобы был интернет».
+
+> **Автор: engelgardt.**

+
+## Скачать
+
+Последний релиз: [**страница релизов**](https://github.com/Engelgardt23/netswitch/releases/latest).
+Архив `netswitch-portable-vX.Y.Z.zip` (~30 КБ).
+
+## Запуск
+
+1. Распакуй куда угодно.
+2. Двойной клик по `netswitch.exe`.
+3. **При первом запуске** программа спросит язык интерфейса (1 — English, 2 — Русский). Ответ запишется в `config.ini` рядом с exe — потом можно поменять руками.
+4. Подтверди UAC (admin нужен для `netsh interface ipv4 set address`).
+5. Выбери сетевой адаптер из списка.
+6. Выбери режим:
+   - **Статический**: введи IP (по умолчанию `10.10.10.1`), маску (по умолчанию `255.255.255.0`), шлюз (опционально).
+   - **DHCP**: подтверди — адаптер вернётся в DHCP для IP и DNS.
+
+## Что фильтруется
+
+В выбор попадают только настоящие проводные физические адаптеры. Wi-Fi, VPN, виртуалки, Hyper-V, VMware, VirtualBox, TAP/TUN, WireGuard, OpenVPN, Tailscale, ZeroTier, Bluetooth, Loopback, WAN Miniport — всё пропускается.
+
+## Проверка обновлений
+
+При каждом запуске тулза стучится в GitHub `/releases/latest` (таймаут 3 секунды). Если есть свежая версия — справа в шапке появится тусклая надпись `доступно обновление (vX.Y.Z)`. Если интернета нет — молчит.
+
+## Конфиг
+
+При первом запуске рядом с `netswitch.exe` появится `config.ini`:
+
+```ini
+# Чтобы сменить язык интерфейса, измените 'language' ниже.
+# Допустимые значения: en, ru
+[General]
+language = ru
+```
+
+## Сборка из исходников
+
+Скрипт один — `netswitch.ps1`. Для пересборки `.exe`:
+
+```
+Install-Module ps2exe -Scope CurrentUser
+Invoke-ps2exe -inputFile netswitch.ps1 -outputFile netswitch.exe -requireAdmin -title "netswitch" -version 1.1.0.0
+```

+# Security policy
+
+Thanks for taking the time to look at this. Even small tools can introduce real
+risk — this one reconfigures network adapters from an elevated process — so
+vulnerability reports are very welcome.
+
+## Supported versions
+
+Only the latest tagged release on GitHub is supported. Older versions will not
+get fixes; please upgrade first.
+
+## How to report a vulnerability
+
+**Please do not open a public issue** for security-sensitive findings.
+
+Use GitHub's private security advisories: go to the
+[Security tab](../../security/advisories/new) of this repo and click
+"Report a vulnerability". GitHub will route it privately.
+
+Please include:
+- The version you tested (the startup banner is enough).
+- Steps to reproduce.
+- An assessment of impact.
+
+Reports are reviewed and addressed on a best-effort basis. A fix and a public
+advisory will be published once the issue is resolved. Reporters are credited
+unless they prefer to stay anonymous.
+
+## Out of scope
+
+- Behavior when run **without** administrator privileges (the tool refuses to
+  start in that case anyway).
+- Issues that require the attacker to already control the user's machine.

Author	SHA1	Message	Date
engel	5ef0d77ca6	v1.1.0: russian/english UI, config.ini, README.ru.md	2026-05-18 11:51:38 +03:00
engel	7350232362	v1.0.3: quiet update hint instead of interactive prompt	2026-05-17 21:41:34 +03:00
Engelgardt23	67447bc7f1	fix(v1.0.2): suppress netsh output to avoid mojibake on RU console 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.	2026-05-17 18:10:09 +03:00
Engelgardt23	e80e673a10	release: v1.0.1 Drop 'made by engelgardt' from the startup banner — author credit stays in README only. Exe now ships the embedded icon (CI uses -iconFile assets/icon.ico).	2026-05-17 18:06:13 +03:00
Engelgardt23	408126f177	ci: pass iconFile to ps2exe so the exe gets the bundled icon	2026-05-17 17:55:00 +03:00
Engelgardt23	c4d98dd5e3	add app icon (assets/icon.ico) + generator script Embed icon into the exe via ps2exe -iconFile. Regenerate with tools/make_icon.ps1.	2026-05-17 17:54:16 +03:00
engel	789c7b3750	refactor: move source into src/ src/netswitch.ps1 (single file, ~150 lines). CI updated to build from this path. Added CONTRIBUTING.md describing layout, build, and release flow. No user-visible behaviour change.	2026-05-16 12:28:10 +03:00
engel	a854d8e3f7	Add CI release workflow, CHANGELOG.md, issue templates - .github/workflows/release.yml: on tag push, build exe via ps2exe, package portable zip, attach SHA-256, create GitHub Release. - CHANGELOG.md: Keep a Changelog format, semver. - .github/ISSUE_TEMPLATE/: bug_report.yml + feature_request.yml + config.yml routing security reports to private advisories.	2026-05-16 11:59:18 +03:00
engel	18eac693e9	SECURITY.md: keep only GitHub private advisories, drop SLA	2026-05-16 11:56:05 +03:00
engel	ebe64363c6	Add SECURITY.md (private vuln reporting policy)	2026-05-16 11:52:34 +03:00
