+# Project instructions
+
+## Mandatory Wiki updates for every release
+
+A release is not complete until the published project Wiki reflects that release.
+Apply this rule to every release, including patch releases and bug-fix-only releases.
+
+Wiki: https://gitea.hrynco.com/hrynco/hrynco-kswitcher/wiki
+
+1. Confirm the release version from `CMakeLists.txt`, the release tag and
+   `Release/README.md`. Use the complete version (for example, `v0.6.17`) and
+   preserve the release channel rules in `README.md`.
+2. Update the latest-version information on the Wiki home pages and any other
+   pages identifying the current release. Update release dates, download links
+   and upgrade instructions where needed. Keep historical version references
+   and compatibility bridge instructions when they are still accurate.
+3. Review the changes since the last release documented in the Wiki, not just
+   the immediately preceding release. Bring the relevant feature pages up to
+   date with the shipped behavior: new, changed and removed functionality,
+   settings, shortcuts, defaults, limitations and troubleshooting. Update
+   screenshots or examples when they no longer match the application.
+   For bug-fix-only releases, check whether documented behavior or workarounds
+   need correction; do not invent feature changes.
+4. Keep English and Ukrainian pages synchronized, including `Home` and
+   `Home-uk`, and preserve working translation and navigation links.
+5. Publish the Wiki changes as part of the release workflow. Read back the
+   published pages and verify the current version, feature descriptions,
+   download links and translation links. A local Wiki edit alone is not enough.
+6. In the release completion report, link the updated Wiki pages and summarize
+   the documentation changes. If Wiki publication or verification is blocked,
+   explicitly report the outstanding step and do not claim the release workflow
+   is complete.
+
+Updating only the release notes or changing only the Wiki version number does
+not satisfy this rule; the current functionality must also be reviewed.
+
+## KSwitcher Files UI
+
+Before changing the file manager UI, read [FILES-UI.md](FILES-UI.md).
+Reuse the shared dialog rendering and layout helpers. Update the document
+when an agreed UI requirement changes.

+# Оформлення KSwitcher Files
+
+Far Manager є зразком для оформлення файлового менеджера. Основне вікно використовує системний заголовок Windows. Панелі, меню й діалоги операцій використовують моноширинний шрифт менеджера та оформлення в стилі Far.
+
+## Спільні елементи діалогів
+
+- Enter активує кнопку у фокусі. Для кнопок із власним малюванням використовуй спільний обробник `dialogButtonEnter`. У підтвердженні скасування початковий фокус стоїть на No.
+
+- При перенесенні вікна між моніторами з різним DPI оновлюй шрифт, висоту рядків панелей і компонування відкритого прогресу копіювання. Перевір перенесення під час активного копіювання.
+- Для власних діалогів використовуй подвійну рамку з одним заголовком у верхній лінії. Звичайний діалог має сіре тло, попередження — темно-червоне тло та білий текст.
+- У ресурсі чи виклику задавай назву кнопки й клавішу доступу. Спільна функція `paintDialogButton` додає квадратні дужки, центрує текст і підсвічує фокус.
+- Нижні секції з кнопками у Copy, Warning і вікні прогресу мають однакову висоту, прив’язану до висоти рядка шрифту. Використовуй `layoutDialogButtons` для такої секції та `centerDialogRow` для інших рядків між роздільниками. Межі секції визначають положення рядка.
+- Поля вводу й випадаючі списки використовують бірюзове тло палітри менеджера. Текст і стрілку вирівнюй вертикально по центру. Прапорці в діалогах операцій використовують позначки `[ ]` та `[x]` і видимий клавіатурний фокус.
+- Повторно використовуй спільне оформлення. Текст, дії та стан операції передавай із коду конкретної операції. Наприклад, Warning повертає відповідь і стан прапорця, а копіювання вирішує, чи застосувати відповідь до наступних конфліктів.
+
+## Діалог Copy
+
+- Вирівнюй підпис Existing files по вертикальному центру списку. Ширше поле списку починається ближче до підпису, а його правий край збігається з правим краєм поля імені.
+- Зберігай однакові проміжки від верхнього роздільника до поля імені й до списку. Підпис, поля та прапорець мають читатися повністю.
+- Відступ після прапорця до нижнього роздільника дорівнює відступу від верхнього роздільника до списку.
+- Кнопки Copy та Cancel стоять по центру компактної нижньої секції. Висота кнопок має вміщати весь текст поточного шрифту.
+
+## Вікно прогресу копіювання
+
+- Секції поточного файла й загального прогресу мають однаковий вертикальний відступ від вмісту до верхньої та нижньої ліній. Cancel стоїть по центру спільної нижньої секції.
+- Обидві шкали займають усю ширину вмісту. Відсотки показуються по центру шкали, а її висота враховує поточний шрифт.
+
+## Попередження про конфлікт
+
+- Після розрахунку остаточної висоти центр Warning збігається з центром вікна прогресу.
+- Remember choice стоїть по вертикальному центру власної секції. Кнопки Overwrite, Skip і Cancel стоять по центру нижньої секції.
+- Tab проходить Remember choice, Overwrite, Skip і Cancel. Стрілки вліво та вправо циклічно перемикають три кнопки в порядку їх розташування.
+- Стрілки вгору й вниз переходять між сусідніми секціями з інтерактивними елементами. У Warning стрілка вгору з ряду кнопок переводить фокус на Remember choice, а вниз із прапорця — на Overwrite.
+
+## Перевірка змін
+
+Відкрий Copy і Warning в одній збірці та порівняй висоту нижніх секцій, центрування, повноту підписів і видимість фокуса. Перевір Tab, стрілки й Esc. Після узгодження нового правила онови відповідний розділ цього документа.

+# LAN mouse, keyboard and clipboard — v0.6.58 (experimental)
+
+KSwitcher discovers other enabled KSwitcher instances, pairs them with the same
+code on both computers, and shares mouse and keyboard through a screen edge.
+The module runs inside the resident process. Multiple paired computers can be
+arranged on a monitor grid. Mouse and keyboard follow neighboring cells, including
+A → B → C, without relaying input through B. New text and images are also shared
+with all online paired computers: history and the active clipboard.
+
+## Files and diagnostic logs
+
+In **Settings → Computers → Manage computers…**, select an online paired
+computer and choose **Send file…**. Both computers need a build with file transfer.
+Files up to 16 MiB travel over encrypted LAN. On the destination, open
+**Incoming files…** to save or discard each file. The save dialog suggests the
+original filename. KSwitcher shows a Windows notification when a file is ready
+to save, and its tray tooltip shows the pending count. Pending files are held
+in memory until saved, discarded, or KSwitcher closes.
+
+To retrieve the current or rotated diagnostic log, enable **Allow paired
+computers to download diagnostic logs** on the computer that owns the logs.
+This setting defaults to off. On the requesting PC, select that computer and
+choose **Download log…** or **Previous log…**. Diagnostic logs may contain
+text copied from applications.
+
+### MCP
+
+In **Settings → MCP**, choose **Copy configuration** and paste the block into
+Codex's `~/.codex/config.toml`. It starts the MCP server over stdio with the
+absolute path to `KSwitcher.Config.exe` and the `--mcp` argument.
+`list_log_computers` returns paired computer IDs and availability.
+`read_diagnostic_log` reads the latest 100 lines by default (1–500 with
+`lines`). Use `offset` to skip newer lines and page backward. Set `previous` to read the rotated log. Omit `peer` for the
+local log or pass a paired computer ID for a remote log. Remote reads need
+the local resident process running and log downloads enabled on the remote PC.
+
+## Set up multiple computers
+
+1. Install the v0.6.58 or newer on every participating PC. Input protocol v2 requires all participants to update; earlier one-pair builds cannot connect. Preserve local data; do not copy pairing identities between PCs.
+2. Open **Settings → Computers → Manage computers…** and enable discovery on both PCs.
+   Only running LAN-enabled KSwitcher instances appear, not generic network devices.
+3. Match the computer name and instance-ID prefix displayed on the other PC.
+   Select each other, generate one code, enter that same code on both, then click
+   Pair on both within two minutes. Spaces, hyphens and uppercase hex are accepted.
+4. Pair each physical input source with every destination it must control. For
+   unrestricted control from any PC, pair every pair of PCs. Drag monitors into
+   neighboring grid cells and arrange the same physical layout relative to each
+   local PC. For A → B → C, A sees B at (1,0), C at (2,0); B sees A at (-1,0),
+   C at (1,0). Enable input sharing on all PCs. The button controls all pairs,
+   independently of the selected list item. Positions save immediately.
+5. Stop MWB or another mouse/keyboard router on both computers before trying
+   KSwitcher input sharing, to avoid two tools forwarding the same events.
+6. Wait for the authenticated input connection. Move the cursor through the
+   configured outer screen edge with no keys or buttons held. After the other
+   computer acknowledges the handoff, both mouse and keyboard control that PC.
+   Crossing another shared edge switches directly to that neighbor. Crossing back
+   into the source computer restores its cursor at the corresponding edge. Empty
+   cells, diagonal-only neighbors and offline PCs do not transfer control.
+
+The source cursor is parked and hidden beneath a tiny no-activation window. A
+small banner identifies remote control; no full-screen layered bitmap is retained.
+The destination uses its own keyboard layout and runs its own hotkeys/snippets.
+The source suppresses forwarded events before its local hotkeys, snippets and
+other low-level hook consumers. Received input is marked so it is not forwarded
+again. Source recent-input tracking and shortcut latches reset when ownership changes.
+
+**Ctrl+Alt+Esc** is emergency return, not the normal switching mechanism. Local
+physical input on a remotely controlled PC takes control back as well. Stop input
+sharing, disabling discovery, forgetting the currently controlled pair, suspension, secure
+desktop changes and connection loss cancel remote ownership. TCP heartbeat loss
+is detected after two seconds; a handoff request expires after one second.
+Held remote keys/buttons are released. Releases blocked by a secure desktop are
+retried when the ordinary desktop is available. Source key-ups for keys already
+sent remotely are consumed after return, avoiding stray local modifier events.
+
+## Layout and limitations
+
+- Positions are relative to this PC. All peers have independent authenticated
+  connections; a failed peer does not disconnect the others. The physical source
+  uses its own grid to choose every destination. Moving a monitor cancels current
+  control safely and applies the updated layout without dropping all connections.
+  Layouts are not synchronized automatically. One source controls a destination
+  at a time. Each grid tile represents an entire PC, not an individual monitor.
+- Geometry uses the virtual desktop's outer bounding rectangle, including negative
+  monitor coordinates. Internal monitor boundaries do not transfer control.
+  Different resolutions map the entry position proportionally. Irregular layouts
+  can have gaps on an outer edge; this is not a per-monitor arrangement editor.
+- Transferring while a key or mouse button is held is intentionally blocked.
+  Dragging works within the controlled computer; dragging objects across PCs is
+  not implemented. There is a short return cooldown to avoid bouncing.
+- Windows can block SendInput to elevated apps and secure desktops. Run both
+  applications at suitable privilege levels for the target programs. The preview
+  does not install a service, bypass UAC or implement remote Ctrl+Alt+Delete.
+- This is Windows input injection, not a virtual USB HID device. Raw-input games,
+  exclusive full-screen applications and special device keys need separate testing.
+
+## Network, authentication and storage
+
+Discovery broadcasts on private IPv4 and link-local interfaces using UDP 45883.
+Input uses TCP 45884. Allow KSwitcher on your private network when Windows asks;
+the preview does not change firewall rules. Broadcast-blocked networks, separate
+VLANs, public IPv4 and IPv6-only networks are not supported by discovery yet.
+A second LAN-enabled KSwitcher cannot use the same ports on one computer.
+
+Input first tries TCP in the usual direction, then reverse TCP after 1.5 seconds.
+If TCP has not authenticated after 5 seconds, the lower-ID peer negotiates an
+encrypted UDP input session on the existing discovery socket (UDP 45883).
+UDP uses fresh session challenges, authenticated encryption, ordered event
+numbers, acknowledgements and bounded retries; duplicated packets do not repeat
+key presses. Two seconds without authenticated traffic or acknowledgement
+progress closes the session and returns control locally. A working UDP session
+stays on UDP until disconnected; it does not oscillate between transports.
+Both PCs must run an updated build to use all fallback methods. Older peers can
+still use the original TCP protocol. No extra ports or external relay are used.
+
+After 15 seconds without a connection, the UI points to **Connection help**.
+The help window can copy PowerShell commands for the actual resident EXE path,
+including a path containing apostrophes. Run each PC's own command in an
+administrator PowerShell on that PC. These commands permit inbound TCP 45884
+and UDP 45883 only from the local subnet; the program does not execute them.
+Moving the EXE may require a new application firewall rule. A timeout alone
+does not establish that the firewall is the cause: check that input sharing is
+enabled on both PCs and that both are running the intended copy.
+
+The instance ID belongs to a data directory, not a hostname/IP address. Discovered
+names and addresses are untrusted. Pairing uses a generated 128-bit code and
+mutual HMAC-SHA256 challenge proofs bound to both instance IDs. The code is never
+transmitted or logged. The pair key is separate from the setup code.
+
+The input channel authenticates both peers with the saved pair key and fresh
+session challenges. Directional AES-256-GCM session keys bind the identities,
+nonces and the input protocol domain. Screen positions determine routing after
+authentication; they are no longer part of the pair channel key. Fixed-size authenticated frames use strict sequence
+numbers, so tampering, reflection and replay are rejected. Input is not dispatched
+until authentication succeeds. This PSK channel does not provide forward secrecy.
+Queues and frame sizes are bounded; overflow disconnects rather than dropping a
+key-up and leaving a key pressed. The input worker never injects Windows input;
+the resident's main thread owns the input state and hooks.
+
+Identity, trust, enablement and screen position stay in DPAPI-protected
+`data/lan-pairing.bin`, outside settings export and OpenBao sync. Do not clone this
+file between installations. Forget a pair on both PCs for bilateral removal.
+Closing the settings window does not cancel pairing or disable sharing.
+
+Disabled discovery has no socket or worker. Input sharing reuses the single LAN
+worker; there is no extra resident executable or service. The main input timer
+runs only while sharing is enabled. The existing configurator talks to the
+resident through local IPC.
+
+## Validation
+
+Tests cover pairing, encrypted frames, replay/tamper rejection, actual loopback
+TCP authentication and bidirectional delivery, all four edges, ownership races,
+source suppression, scan codes, clicks/wheel, emergency return, held-key release,
+blocked injection, secure desktop recovery, exact one-pixel movement and timeout.
+Tests additionally exercise three actual TCP hubs, independent reconnect,
+A → B → C and back, vertical turns, unavailable neighbors, stale ownership,
+modifier delivery to only the active destination, and local shortcut recovery.
+UI tests drag three monitors and check persistence.
+
+Three physical computers still need an end-to-end trial for their adapters,
+firewalls, displays and application privilege levels. The automated TCP tests
+use local sockets, and input-state tests use simulated desktop environments;
+they do not claim a completed three-machine hardware test.
+
+## v0.6.58 connection fixes
+
+Saved trust keeps TCP listeners available even when discovery announcements are missed. Working authenticated input sessions no longer depend on discovery presence. Pair saved is distinct from input connected; the list refreshes every second. A changed instance ID requires a new pairing. Keep each PC's own data folder during upgrades. Connection state changes and listener Windows errors are written to the diagnostic log.

 # Latest Windows release

-## v0.2.0 — 2026-10-28
+## v0.6.77 — 2026-11-13

- Log failed conversions and suspicious repeated hotkeys with recent attempt context.
- Include bounded text and layout diagnostics to help reproduce conversion failures.
- Add the **Write log** setting and preserve the previous log during rotation.
- View current and previous logs inside the app with Time, Attempt, Event, and Details columns.
- Copy selected rows and clear the selected log from the viewer.
- Fix the log viewer closing on focus; give column headers a distinct background.
+The screenshot editor remembers the local pencil smoothing default across
+restarts. Adjust the slider with no pencil stroke selected, or use **Apply to
+all**, to save the value for new strokes. Adjusting a selected stroke changes
+only that stroke.

-Repeated hotkeys are diagnostic clues, not proof of failure. Successful paste dispatch does not
-verify that the target editor applied the replacement. Text diagnostics are enabled by default
-and can be disabled with **Write log**.
+**Українською.** Редактор скріншотів зберігає типове згладжування олівця на
+цьому ПК та відновлює його після перезапуску. Змініть повзунок без виділеного
+штриха олівця або натисніть **Apply to all**, щоб запам’ятати значення для
+нових штрихів. Зміна виділеного штриха впливає лише на нього.

-Download **KSwitcher-win-x64.zip**, extract the entire archive to a writable folder,
-and launch `KSwitcher.exe`. Keep `dictionaries/` next to the executable.
-The archive contains the application, offline dictionaries, documentation and license notices.
-It does not contain personal settings or clipboard history.
+## v0.6.76 — 2026-11-13

-For upgrades, exit KSwitcher first. Back up any edited dictionaries before replacing files.
-Keep your existing `data/` directory to retain settings and clipboard history.
-`SHA256SUMS.txt` contains the checksum of the archive.
+Incoming LAN files suggest their original filename when saved. KSwitcher shows
+a Windows tray notification when a file is ready to save, and the tray tooltip
+shows the pending count.

-This folder holds only the latest compiled version; older versions remain in Git history.
+**Українською.** Під час збереження вхідного LAN-файлу пропонується його
+оригінальна назва. KSwitcher показує сповіщення в треї, коли файл готовий
+до збереження. Підказка іконки показує кількість файлів у черзі.

-To refresh it from source:
+## v0.6.75 — 2026-11-13

-```powershell
-.\build.ps1 -Stage -Test
-.\package.ps1 -PublishRelease
-```
+Conversion cancels earlier when input changes and skips restoring an untouched
+clipboard. Diagnostic records identify the active conversion behind `busy`,
+separate clipboard and paste verification timings, and retain a text-free
+summary of verified pastes that take at least two seconds. MCP log reads
+support `offset` to page backward.

-Commit the updated ZIP and checksum together with the corresponding source changes.
+**Українською.** Конвертація раніше скасовується після зміни вводу й пропускає
+відновлення буфера, якщо його не змінювала. Діагностика показує активну спробу
+для `busy`, окремий час роботи з буфером і перевірки вставки, а також зберігає
+підсумок перевірених вставок від двох секунд без скопійованого тексту. У MCP
+параметр `offset` дає змогу читати старіші рядки.
+
+Explicit replacements now accept digits and internal apostrophes in the source word, for example нав1язав=навʼязав. Invalid entries identify the offending pair.
+
+**Українською.** Явні заміни підтримують цифри й внутрішні апострофи у вихідному слові, наприклад нав1язав=навʼязав. Повідомлення про помилку показує проблемну пару.
+
+## v0.6.74 — 2026-11-13
+
+- Send files up to 16 MiB to a selected paired PC over encrypted LAN. Save or discard them from **Incoming files**.
+- Download current and previous diagnostic logs from paired PCs that explicitly allow remote log downloads.
+- Copy the Codex configuration from **Settings → MCP**. The MCP server lists paired PCs and reads local or remote diagnostic logs.
+- Search contacts in the **Languages for a chat** table. **Copy selected** in Diagnostics now uses normal clipboard synchronization.
+
+**Українською.** Передавайте файли до 16 МіБ вибраному спареному ПК зашифрованою локальною мережею. У **Incoming files** можна зберегти або відхилити файл. Поточний і попередній журнали доступні для завантаження після ввімкнення відповідного дозволу на віддаленому ПК. У **Settings → MCP** можна скопіювати конфігурацію Codex для читання локальних і віддалених журналів. У таблиці **Languages for a chat** додано пошук контактів, а **Copy selected** у діагностиці тепер проходить через звичайну синхронізацію буфера.
+
+## v0.6.73 — 2026-11-13
+
+After moving KSwitcher, launch it from its current folder. If Windows autostart
+still points to the old location, KSwitcher updates the path automatically when
+the previous executable is missing and the process has sufficient rights. If
+the previous copy may still be in use or the repair needs administrator approval,
+choose **Update autostart path** and confirm UAC if prompted. To check again,
+click **Save** in Settings without changing the autostart options.
+
+**Українською.** Після перенесення KSwitcher запустіть його з нової папки.
+Якщо автозапуск і далі вказує на старий шлях, KSwitcher виправить його
+автоматично, коли старий файл відсутній і прав достатньо. Якщо стара копія
+ще може використовуватися або потрібні права адміністратора, натисніть
+**Update autostart path** і підтвердьте UAC, якщо з’явиться запит. Для повторної
+перевірки натисніть **Save** у налаштуваннях без зміни параметрів автозапуску.
+
+## v0.6.72 — 2026-11-12
+
+Edit snippets directly in **Settings → Snippets**. **Save snippets** applies
+snippet edits independently of the settings draft. Find OCR options in
+**Clipboard** and open backup and synchronization, paired computers, and
+logging from **Sync**, **Computers**, and **Diagnostics**, respectively.
+
+**Українською.** Редагуйте сніпети безпосередньо у **Settings → Snippets**.
+Кнопка **Save snippets** зберігає їх окремо від чернетки налаштувань.
+Параметри OCR тепер у **Clipboard**. Для синхронізації, спарених ПК та
+журналу є вкладки **Sync**, **Computers** і **Diagnostics**.
+
+## v0.6.71 — 2026-11-12
+
+After navigating snippet suggestions with **↑ / ↓**, press **Enter** to
+insert the selected snippet and close the list. The editor does not receive
+that keypress. If you have not navigated the list, **Enter** still goes to
+the editor. **Tab** and mouse selection also work.
+
+KSwitcher skips suggestions when VS Code's EditContext supplies the bounds
+of the whole line in place of the text caret. See the [FAQ](https://gitea.hrynco.com/hrynco/hrynco-kswitcher/wiki/FAQ)
+for the VS Code workaround.
+
+**Українською.** Після вибору підказки клавішами **↑ / ↓** натисніть
+**Enter**, щоб вставити сніпет і закрити список. Редактор не отримує це
+натискання. Якщо ви не переміщалися списком, **Enter** і далі надходить
+до редактора. Також можна вибрати сніпет через **Tab** або мишею.
+
+KSwitcher приховує підказки, коли EditContext у VS Code повертає координати
+всього рядка замість текстового курсора. Обхідний шлях описано у [FAQ українською](https://gitea.hrynco.com/hrynco/hrynco-kswitcher/wiki/FAQ-uk).
+
+## v0.6.70 — 2026-11-12
+
+Snippet suggestions are anchored to the text caret. KSwitcher uses the
+editor's caret location or text accessibility information, including for
+thin carets and wrapped text. If the editor provides no caret position,
+the list stays hidden. Full triggers continue to expand automatically.
+
+**Українською.** Підказки сніпетів прив’язані до текстового курсора.
+KSwitcher використовує координати курсора або дані доступності редактора,
+зокрема для тонкого курсора й перенесених рядків. Якщо редактор не надає
+позицію текстового курсора, список не відкривається. Повні тригери й далі
+спрацьовують автоматично.
+
+## v0.6.69 — 2026-11-12
+
+Snippet autocomplete opens beside the text caret as soon as you type `;` at
+the start of a trigger. Other triggers offer suggestions after three
+characters. The list stays open while you type, resizes to fit the matching
+triggers, and respects application restrictions. Use **↑ / ↓** and **Tab** or
+click a suggestion to insert it. Press **Esc** to dismiss the list. Full
+triggers still expand automatically.
+
+**Українською.** Автодоповнення сніпетів відкривається біля текстового курсора,
+щойно ви вводите `;` на початку тригера. Для інших тригерів підказки
+з’являються після трьох символів. Список залишається відкритим під час набору,
+підлаштовує ширину під відповідні тригери й враховує обмеження за програмами.
+Виберіть сніпет клавішами **↑ / ↓** і **Tab** або мишею. **Esc** закриває
+список. Повні тригери й далі спрацьовують автоматично.
+
+## v0.6.68 — 2026-11-12
+
+With **Start with Windows** and **Start with Windows as administrator** enabled,
+opening the regular KSwitcher after exiting a development build requests
+administrator approval when needed. UAC prompts on the secure desktop still
+require local input.
+
+**Українською.** Якщо ввімкнено **Start with Windows** і **Start with Windows as administrator**,
+звичайний KSwitcher після закриття dev-збірки за потреби запитує запуск від
+адміністратора. Запити UAC на захищеному робочому столі підтверджуйте
+безпосередньо на цьому ПК.
+
+## v0.6.67 — 2026-11-12
+
+Mouse buttons and wheel actions now use the profiles on the PC receiving
+input through KSwitcher Computers or Mouse Without Borders. Update the
+receiving PC and configure its actions in **Settings → Mouse**.
+
+**Українською.** Кнопки й коліщатко тепер працюють за профілями ПК,
+який отримує ввід через KSwitcher Computers або Mouse Without Borders.
+Оновіть цей ПК і налаштуйте дії в **Settings → Mouse**.
+
+## v0.6.66 — 2026-11-12
+
+If Windows rejects registration of the notification-area icon at sign-in or
+after Explorer restarts, KSwitcher retries about once a second until the
+icon is registered. Settings become accessible from the icon without
+restarting KSwitcher.
+
+**Українською.** Якщо Windows не приймає значок KSwitcher в області
+сповіщень під час входу або після перезапуску Провідника, KSwitcher
+повторює спробу приблизно щосекунди. Коли значок з’явиться, з нього
+можна відкрити налаштування без перезапуску KSwitcher.
+
+## v0.6.65 — 2026-11-12
+
+Use **Settings → Mouse → +** beside **Mouse events** to capture and name a
+vertical or horizontal wheel direction. Capturing a known button or an
+already registered direction selects its existing row. A new signal is
+accepted only when Windows delivers it through both the test and runtime
+input paths. A configured wheel action replaces scrolling for that direction
+where the profile applies.
+
+OpenBao now backs up all KSwitcher Settings, including mouse events, bindings,
+application profiles, startup, clipboard history limits, and OCR preferences.
+Update all clients that share a server profile before syncing. Downloading an
+older backup preserves local settings for fields it never included. After
+reinstalling Windows, reconnect to OpenBao and choose **Download remote**.
+Executable paths and optional OCR software must still be available on the
+restored PC. Clipboard contents and Windows credentials stay on the device.
+
+**Українською.** У **Settings → Mouse** натисни **+** біля **Mouse events**,
+щоб додати напрямок прокручування. Відомий сигнал виділить наявний рядок.
+OpenBao тепер зберігає всі налаштування KSwitcher, зокрема профілі миші,
+OCR й автозапуск. Перед синхронізацією онови всі клієнти спільного профілю.
+Після перевстановлення Windows підключись до OpenBao й натисни
+**Download remote**.
+
+## v0.6.64 — 2026-11-12
+
+The new **Settings → Mouse** tab lets you assign actions to mouse buttons and supported double-clicks. Use **Global** for fallback actions and create profiles for one or more applications. Edit a profile with a double-click, and enable or disable it with the **Active** checkbox. Choose applications by pointing at a window or opening an executable or shortcut.
+
+Actions include keyboard combinations, browser navigation, launching applications, and system volume. Volume actions have a configurable step and an on-screen indicator. When Windows reports separate press and release events, holding the button repeats the volume change at increasing speed.
+
+Use **Test mouse buttons here** to check which events Windows delivers. Mouse profiles are stored on the current PC. The configurator also keeps fixed-size settings dialogs fitted when moving them between displays with different scaling.
+
+## Upgrade
+
+Choose **Update** in the tray menu. Legacy v0.3.0–v0.4.1 clients first receive the v0.4.2 compatibility bridge, then the current full release. v0.2.3 and earlier require manual installation.
+
+For a manual upgrade, exit KSwitcher and its configurator and screenshot editors, then extract the entire **KSwitcher-win-x64.zip** into its installation folder. Verify it with **SHA256SUMS.txt**. Keep personal data, customized dictionaries and tools. Keep the three KSwitcher executables together.
+

+KSwitcher portable utilities
+
+Put your trusted portable .exe utilities directly in this tools folder,
+beside this README.txt. Right-click the KSwitcher tray icon and open Tools.
+For example: tools/StayHere.exe appears as Tools > StayHere.
+
+The list refreshes each time the tray menu opens. Subfolders and shortcuts
+are not listed. Utilities start only when you choose them, with this folder
+as their working directory. Closing KSwitcher does not close a utility.
+
+StayHere.exe is bundled. Choose Tools > StayHere to start it; it starts
+enabled, prevents automatic sleep, and sends F15 after 3 minutes of inactivity.
+Left-click its tray icon to pause/resume; right-click for Exit. See StayHere-README.md.
+It does not start automatically with KSwitcher or bypass Windows locking.
+
+Add other utilities separately. Updates preserve your own files in this folder;
+bundled StayHere.exe and documentation may be refreshed. Utilities are not
+transferred by settings synchronization.
