- **TEST ON** in the rule editor now switches to **TEST OFF** and highlights while the live LED test is running, so you can see that the test is active.

- Rule editor actions (save, duplicate, remove, and close) use clearer buttons that match the rest of the dark theme.
- Fixed LED sideeffects when editing a rule 

- **Constellation Alpha (ALPHA-R / ALPHA-L) on MongoosT-50CM2 Base** — follow-up to 3.2.4.1 for rigs where the grip stayed dark. LED Control Bench, **TEST ON**, and profile rules now update that grip the same way VIRPIL Shift and the Configurator do.

- **Device list** — the stick is shown as the CM2 base plus the Alpha grip, so LED targets attach to the grip instead of a generic T-50 base name. This is more reliable when VPC Watcher is also running.

- **Other devices** — control panels, the CM2 throttle, Alpha Prime, and Aeromax lighting are unchanged.

- **Constellation Alpha (ALPHA-R / ALPHA-L) on MongoosT-50CM2 Base** — grip LEDs now respond to LinkTool rules, rule **TEST ON**, and manual device LED tests (same throttle mode-switch profiles that already drove CP1/CP2/Throttle).

- Added bit operations in telemetry transform UI for Elite Dangerous.

- Now ARM panel could be hidden or pinned.

- Regenerated EN/RU/FR user guides and EN/RU Quick Start PDFs in `docs/pdf/`.

- **Settings → Profiles** — configure LED profile bindings from telemetry (per simulator, multiple criterion rows, first match wins).

- Enable **Autoload profile from telemetry identity** with **Autoload LED profiles**; debounce delay and **Capture values** for live criteria.

- MSFS **Aircraft identity (ATC)** sim var pack (`ATC TYPE`, `ATC MODEL`) for identity-based profile switching.

- DCS World LED profiles autoload

- New **Profiles** settings tab (autoload options and telemetry bindings); cleaner **LED animation timing** layout with aligned scales and compact sliders.

- **Input polling interval** control moved into the LED timing panel alongside blink, flash, and breathe frequencies.

- Updated EN/RU/FR manuals and Quick Start; regenerated PDFs in `docs/pdf/`.

- **Restore LEDs on exit** and **Safe/STOP** now send a firmware LED reset (command 100) when needed, including when configured-color idle fallback would otherwise send nothing — matching Diagnostics “Reset LEDs” behavior.

- **Reset LEDs before start** always uses firmware reset on start/stop (all connected devices with a valid LED command), not only “turn off” PC overrides.

- Closing the app no longer throws when shutdown runs async cleanup (deferred window close after prepare-for-shutdown).

- Configured-color idle fallback falls back to firmware defaults when no LED frames can be built.

- Target-conflict warnings only appear when two enabled rules share the same LED **and** the same trigger (e.g. same telemetry parameter), reducing false “overridden” chips on large profiles.

- Sidebar version label binds to the main window again (always shows the running build).

- Shipped PDF manuals and Quick Start guides (EN, RU, FR) regenerated with the installer build.

# VIRPIL Controls LinkTool 3.2.3.3

### Reliability

- Stopping LinkTool now cancels in-flight rule evaluations and drains the USB LED output pipeline before idle or reset colors are applied, reducing race conditions when you stop or exit quickly.

- **Save profile as…** is ignored while a profile is still loading or autosave is suppressed, so you no longer trigger a save against a half-loaded rules buffer.

### UI

- MSFS SimVar and X-Plane dataref editor dialogs use clearer command bindings and smoother open/close motion (modal backdrop and window animations).

### Documentation

- Shipped PDF manuals and Quick Start guides (EN, RU, FR) regenerated with the installer build.

# VIRPIL Controls LinkTool 3.2.3.2

### Device support

- CDT-AEROMAX flightsticks (and similar host+grip LED layouts) now receive grip-zone LED updates from LinkTool when manual testing, running rules, or resetting LEDs. The app mirrors the legacy onboard (102) and grip (103) HID transit commands on the same host device path.

### Reliability

- Focused hotfix after 3.2.3.1 for users who saw stick LEDs unchanged in Diagnostics while throttles or other devices worked correctly.

### Documentation

- Shipped PDF manuals and Quick Start guides (EN, RU, FR) regenerated with the installer build.

# VIRPIL Controls LinkTool 3.2.3.1

### Simulators and telemetry

- Fixed **iRacing** IRSDK shared-memory telemetry when the live session map exceeds 1 MiB: LinkTool now expands the memory view from the IRSDK header so Speed, Rpm, tyre temps, flags, and other curated parameters are read correctly on track.

### Documentation

- Regenerated bundled PDF manuals for the 3.2.3.1 release.
- Download portal: [software.virpil.com](https://software.virpil.com/)

# VIRPIL Controls LinkTool 3.2.3.0

### Simulators and telemetry

- Added **iRacing** shared-memory telemetry (IRSDK) with bundled parameter catalog and simulator icon in the dashboard.
- Expanded **Elite Dangerous** support: journal file reader exposes `Journal.*` keys for LED rules; bundled profile templates for status, combat, exploration, SRV, and Odyssey on-foot play.
- Added bundled **telemetry preset packs** for MSFS SimVars/LVars and X-Plane 12 datarefs, with racing-oriented drawer grouping in Telemetry Lab.

### LED rules and profiles

- New LED animation modes: **Breathe** (per-rule or global frequency) and **Strobe** (duty cycle).
- Gradient rules support **Pulse**, **Blink**, and **Flash** animation on the mapped color ramp.
- **Duplicate rule wizard** clones an existing rule to additional LEDs on the same device with a guided target picker.
- Bundled **profile templates** (DCS, MSFS, LMU tyres, Elite status, and more) with template picker and per-simulator autoload fallback.
- Fixed **Restore LEDs on exit** regression from 3.2.2.3: connected devices again receive idle/firmware fallback when LinkTool closes (Settings → General → Restore LEDs on exit).

### UI and shell

- Refreshed **guarded switch** arm-panel sprites and export pipeline for START/STOP visuals.
- Major **ViewModel refactor**: shell, runtime, devices, rules, settings, and telemetry coordinators replace the legacy monolithic main window view model (same UI, easier maintenance).

### Documentation

- Updated user manuals and Quick Start guides (**English, Russian, French**) for new simulators, preset packs, duplicate-rule wizard, **Breathe** / **Strobe** rule modes, gradient animation, and exit LED behavior.
- Regenerated bundled PDF manuals for the 3.2.3.0 release (including a documentation refresh for Breathe/Strobe coverage).
- Download portal: [software.virpil.com](https://software.virpil.com/)

# VIRPIL Controls LinkTool 3.2.2.3

### X-Plane 12 — native RREF telemetry

- Fixed X-Plane 12 telemetry not appearing in Telemetry Lab: RREF responses use a 5-byte header (`RREF\0` or `RREFO`); LinkTool now parses subscription IDs from the correct offset so subscribed datarefs populate the snapshot.

- Improved UDP session resilience: automatic retry when the native RREF session ends unexpectedly, periodic resubscribe, and clearer log warnings when no valid payloads arrive.

- LAN discovery now maps a discovered simulator on the same PC to `127.0.0.1` instead of a LAN address.

- Default local UDP listen port for new installs is **49003** (avoids conflict with X-Plane legacy send port **49001**). Existing saved settings are unchanged.

### Settings and documentation

- X-Plane 12 Integrations hint text and manuals (**English, Russian, French**) now explain legacy RREF port **49000** vs X-Plane Network DATA port **49010**, and that transport values must be set explicitly under **Settings → Integrations → X-Plane 12**.

- LinkTool pushes the current dataref list to the UDP service when ARMing, so telemetry can start without an extra Save step after editing datarefs.

### Documentation

- Regenerated bundled PDF manuals and Quick Start guides for the 3.2.2.3 installer.

- Download portal: [software.virpil.com](https://software.virpil.com/)

### UI

- **Telemetry Lab** header and layout polish.

### Documentation

- Updated manuals and regenerated bundled PDFs.

Download: [software.virpil.com](https://software.virpil.com/)

# VIRPIL Controls LinkTool 3.2.2.0

### LED rules — telemetry gradients

- Added a new **Gradient** rule type that maps one numeric telemetry parameter to LED color using ordered **color stops** (value + color).

- Ideal for continuous values such as **tyre** or **brake temperature** per wheel — four corners need four gradient rules instead of many separate threshold rules.

- The rule editor includes a dedicated gradient panel with parameter selection, stop list, add/remove stops, and live preview.

- Gradient rules persist in `.led.json` as `gradientRule`, load from legacy profiles, and interpolate within the VIRPIL **RGB222 64-color palette** at runtime.

### Diagnostics

- Improved **bootstrap startup logging**: LinkTool now writes to every writable log target it finds (install folder, LocalAppData, and Temp) so support can locate `linktool-bootstrap.log` even when the install path differs from expectations.

- Added a **location pointer** file in Temp and smarter **Open latest log** / export behavior that picks the newest bootstrap log across known locations.

### Documentation

- Updated user manuals and Quick Start guides (**English, Russian, French**) with gradient rule setup, tyre/brake temperature examples, and editor behavior.

- Download portal: [software.virpil.com](https://software.virpil.com/)

Note!!! Breaking changes.

Virtual LED's tunining done for a certain VPC devices. Some LED's could be still broken.

# VIRPIL Controls LinkTool 3.2.1.2

### Updates

- The **Settings → Updates** tab now shows current and latest version cards, the active update feed, installer cache status, and inline release notes from the updater backend.

- You can **browse, download, and install previous published versions** to downgrade LinkTool when a newer build does not suit your setup.

- Added **French localization** for the expanded update and downgrade UI strings.

### Device preview

- **2D schematic LED overlays** on reference photos now use shape-aware highlights — square, circle, or rectangle — so lit buttons match the physical control layout more closely.

- Expanded **2D schematic anchor coverage** for Alpha Prime L/R, SharKa-50, Control Panel #1/#2, VMAX Prime, and CM2/CM3 throttles.

- **Double-click or right-click an LED** in 2D preview to start **Create rule** for that LED, matching the button monitor workflow.

### Input monitor

- The button input monitor **auto-scrolls to the pressed button**, keeping large button grids visible while you test controls.

### Reliability

- Improved USB-input algorithms

- Live input tracking now **merges USB feature-report axis snapshots** with HID button state so axis values stay available even when the primary input stream is button-only.

### Documentation

- Regenerated bundled PDF manuals (**English, Russian, French**) and Quick Start guides (**English, Russian**) for the 3.2.1.2 installer.

- Download portal: [software.virpil.com](https://software.virpil.com/)

# VIRPIL Controls LinkTool 3.2.1.1

### Device preview

- Device preview now supports a **2D numbered LED photo** view alongside the existing **3D model** — switch modes to inspect LED positions on a flat reference image when that is easier than orbiting the mesh.

- Added a **button input monitor** in the preview window: live button cells highlight on press, tooltips show control names, and double-click or right-click a button to start **Create rule** for that input.

- Improved **Control Panel #2** and Constellation ALPHA 3D LED index remapping and gear-strip highlighting for more accurate on-model LED alignment.

### Rule workflow

- Rule input capture and the rule editor now use clearer **physical input hints** when matching buttons and LEDs to the selected device.

- Corrected **PhID** values in device metadata so some panels and throttles resolve identity more reliably during preview and rule targeting.

### Documentation

- Regenerated bundled PDF manuals (**English, Russian, French**) and Quick Start guides (**English, Russian**) for the 3.2.1.1 installer.

- Download portal: [software.virpil.com](https://software.virpil.com/)

# VIRPIL Controls LinkTool v3.2.1.0

### Device 3D preview

- Added **Device preview** — a resizable window with a live **3D model** that mirrors LED output from the selected connected device while LinkTool is running.

- LED colors update from live device output, active rules, and rule-editor preview so you can see lighting on the mesh instead of only in the LED list.

- **Show LEDs** flashes all addressable LEDs, then highlights them with a glass-lens overlay; **Center view** resets the default camera framing; clicking an LED can open **Create rule** for that target.

- **Supported models in this release:** MongoosT-50 **CM2** and **CM3** throttles, **Control Panel #1**, **Control Panel #2**, **SharKa-50 Control Panel #3**, and **Alpha Prime R** grip. Other VIRPIL devices may appear in the list but do not yet have full 3D LED mapping.

### Rule workflow & LED output

- Improved live rule matching and LED fallback behavior for preview and device output, including clearer handling of unruled LEDs and editor-focused rules.

- Throttle button LEDs and Alpha Prime R grip LED fields use improved material indexing and UV-based field detection for more accurate on-model highlighting.

### Documentation

- Updated bundled PDF manuals (**English, Russian, French**) and Quick Start guides (**English, Russian**) for the 3.2.1.0 installer.

- Download portal: [software.virpil.com](https://software.virpil.com/)

# VIRPIL Controls LinkTool 3.2.0.1

### MSFS / Prepar3D SimConnect

- Fixed SimConnect unit registration for **string** and **boolean** MSFS SimVars — string variables no longer send an invalid units field, and bool variables use the correct **Bool** unit so telemetry subscriptions register reliably.

- Shared the same units logic between MSFS and Prepar3D SimConnect sessions for consistent behavior across simulators.

### MSFS SimVars editor

- Refreshed the **MSFS SimVars** list with a denser card layout, clearer **type · units** summary on each row, and polished enable/disable toggle buttons.

- SimVar editor and list rows now update the type/units summary immediately when you change data type or units.

### X-Plane Datarefs

- Compact dataref cards with tighter spacing and improved scrolling in the **X-Plane Datarefs** view.

- Reduced focus quirks when clicking through the dataref list.

### Account & support

- **Account → Tickets** now shows a clear signed-out state with a sign-in prompt instead of an empty ticket panel when you are not logged in.

### Dashboard

- Improved rule editor overlay layout and scaling on smaller dashboard widths.

### Documentation

- Updated bundled PDF manuals (**English, Russian, French**) and Quick Start guides (**English, Russian**) for the 3.2.0.1 installer.

# VIRPIL Controls LinkTool 3.2.0.0

## English

### Telemetry AI (EXPLAIN)

- Added **EXPLAIN** — a plain-language help action for telemetry parameters in **Telemetry lab** and in the telemetry rule editor. Click the question/comment icon on a parameter row to get a short description in your selected UI language.

- EXPLAIN uses the **currently selected simulator**, parameter name, group, and live value (when available) so answers stay relevant to the sim you are configuring.

- Responses are **cached locally** on disk. Repeat questions for the same parameter show **Cached answer** immediately and reduce API usage.

### AI Integrations settings

- New **Settings → AI Integrations** page with an enable toggle, **Active provider** selector, and sub-tabs for **Groq**, **ChatGPT (OpenAI)**, and **Claude (Anthropic)**.

- **Groq** remains the recommended free default. ChatGPT and Claude use separate developer API keys and billing from chat subscriptions.

- API keys are stored in LinkTool settings on your PC. Missing-key messages point to **Settings → AI Integrations** rather than technical environment-variable names.

### Documentation

- Updated English, Russian, and French user manuals and Quick Start guides with **AI Integrations** setup, **EXPLAIN** workflow, API key vs subscription notes, and Telemetry lab guidance.

- Regenerated bundled PDF manuals (**English, Russian, French**) and Quick Start guides (**English, Russian**).

# VIRPIL Controls LinkTool 3.1.2.1

### War Thunder

- Added a separate **poll interval** setting for War Thunder HTTP telemetry, independent of the per-request timeout. Tune how often LinkTool calls `/state` and `/indicators` without changing how long each request may wait.

- **Settings → Integrations → War Thunder** now exposes poll interval (default `250` ms) and request timeout (default `500` ms) in dedicated controls.

### Racing sim telemetry

- **Le Mans Ultimate** shared memory reading now covers a broader set of session, vehicle, and wheel parameters, including lap timing, fuel, flags, and pit state, with improved yellow-flag detection.

- **Automobilista 2** and **Assetto Corsa Evo** shared memory layouts were audited and expanded with additional flag and LED-focused parameters for more reliable race-state rules.

### Rules

- **Between** range thresholds now accept hyphen-separated values (for example `32-33`) in addition to comma, semicolon, and `..` formats. Reversed ranges are normalized automatically.

### UI

- Reorganized **Settings → Integrations** into clearer per-simulator tabs, including a dedicated War Thunder section.

- Flag-related telemetry parameters are grouped together in the telemetry parameter list for easier rule authoring in racing titles.

### Documentation

- Updated English, Russian, and French user manuals and Quick Start guides for the War Thunder poll/timeout settings and integration layout changes.

- Download portal: [software.virpil.com](https://software.virpil.com/)

# VIRPIL Controls LinkTool 3.1.2.0

### Button rules

- Restored **state-based button rule evaluation** by reading the VIRPIL hardware feature report alongside HID input. Toggle switches and multi-position controls (for example throttle mode selectors) now keep LEDs lit according to the current position, matching legacy LinkTool v2.9 behavior.

- **Pressed**, **Released**, and **Changed** modes again reflect real device state instead of reacting only during movement or while a button is held.

### UI

- Fixed the misaligned **Add rule** icon in the empty rules panel.

### New simulator support
- **Le Mans Ultimate** — live telemetry via the official **`LMU_Data`** shared-memory map. Select LMU on the Dashboard, confirm **Settings → Integrations → Shared Memory**, and use ~60 rule parameters (RPM, speed, fuel, tyres, flags, session info) while on track.
- **Project Motor Racing** — binary **UDP telemetry** on port **7576** (direct or multicast). Enable UDP in the game, configure **Settings → Integrations → Project Motor Racing**, and use ~90 parameters including throttle, RPM, tyre temps, and lap data.
### Telemetry Lab
- Standalone **Telemetry lab** window with search, watchlist, grouped parameters, and live value highlighting for debugging rules and exploring sim data.
- Numeric values in Telemetry lab are formatted to **two decimal places** for easier reading.
### Localization
- Added **French (Français)** UI localization — select **Français** under **Settings → General → Language** for a fully translated interface alongside English and Russian.
### Reliability
- Fixed **Project Motor Racing** vehicle telemetry decoding so full on-track parameter sets (~90 values) are published instead of session-only data.
- PMR UDP settings now **reconfigure live** when changed in Integrations without restarting LinkTool.
### Documentation
- Regenerated bundled PDF manuals (**English, Russian, French**) and Quick Start guides with **Le Mans Ultimate**, **Project Motor Racing**, Telemetry lab workflow, and French language setup.
- Download portal: [software.virpil.com](https://software.virpil.com/)

# VIRPIL Controls LinkTool 3.1.0.2

### LED profiles

- **Autoload LED profiles** now remembers the **last profile separately for each simulator**. On startup and when you switch simulators, LinkTool loads that simulator’s last profile instead of always reopening the single most recently opened file.

- Existing settings are migrated automatically: if you already had a global last profile, it is assigned to your last selected simulator.

### Rule editor

- Added a default **Elite Dangerous** parameter list to the telemetry parameter dropdown, so common status.json fields are easier to pick when writing rules.

- Fixed filter-as-you-type in editable parameter ComboBoxes so typed text is no longer cleared while the list narrows.
- Fixed Elite Dangerous profile load

### Reliability

- LED target selections on a rule are preserved when the output device is temporarily offline during a device refresh.

### UI

- Fixed title-bar **Check for updates** icon alignment so it centers correctly inside its button cap (matching the theme and PDF actions).

### Documentation

- Regenerated bundled **English and Russian** PDF manuals with per-simulator **Autoload LED profiles** workflow, Quick Start steps, and updated download links to [software.virpil.com](https://software.virpil.com/).

# VIRPIL Controls LinkTool 3.1.0.1

### Application shell

- Added **minimize to tray**: enable **Settings → General → Minimize to tray** to hide LinkTool from the taskbar when minimized and keep it in the notification area. Double-click the tray icon or use the context menu to restore the window.

### Search and variable editors

- Added **search fields** for large variable lists on the **MSFS SimConnect variable editor** (SimVars and LVars columns), **X-Plane 12 Datarefs** page, and the **telemetry snapshot drawer** on the Dashboard. Filter by variable name, display name, or live value.

- Added **filter-as-you-type** for the telemetry parameter dropdown in the rule editor, so long parameter lists are easier to narrow down while writing conditions.

### MSFS SimConnect variable editor

- Reworked the **SimConnect variable editor** into a clearer two-column **SimVars / LVars** deck with compact row actions and inline validation feedback.

- Added **duplicate-name validation** for enabled definitions, with background validation scheduling so large imported lists stay responsive.

- Improved save/import guardrails: LinkTool warns when enabled definitions still have validation issues.

### Telemetry lab and rule workflow

- Added **Telemetry lab**, a separate resizable window for exploring live simulator parameters with search, group filters, watchlists, numeric deltas, freeze snapshot, and always-on-top mode.

- Added row actions in Telemetry lab: **watch** parameters per simulator, **copy** parameter names, and **create a telemetry rule** that opens the Dashboard editor with the parameter already filled in.

- Improved Telemetry lab performance and usability for high-frequency shared-memory simulators, including smoother live updates and clearer themed controls.

### Racing simulators and shared memory

- Added **Assetto Corsa Evo** telemetry through built-in Windows shared memory maps (`Local\acevo_pmf_*`). No plugin or mod install is required.

- Added **Automobilista 2** telemetry through the Project CARS 2 shared memory layout (`$pcars2$`).

- Added **Settings → Integrations → Shared Memory** with dedicated setup panels for **Automobilista 2** and **Assetto Corsa Evo**, including poll interval tuning from `10` to `200` ms.

### Documentation

- Updated bundled **English and Russian** user guides with tray behavior, variable search, MSFS SimVar editor workflow, Telemetry lab usage, and Shared Memory integration setup.

# VIRPIL Controls LinkTool 3.1.0.0

## English

### Simulator and telemetry

- Added **X-Plane 12** support with a dedicated **Datarefs** page for managing telemetry variables used in LED rules.

- Expanded **Microsoft Flight Simulator 2020 / 2024** integration: SimVar definitions now support both **SimVars and LVars**, with improved validation and editing in the MSFS SimVars view.

- Added **Import legacy Link Tool vars** for MSFS, making it easier to bring forward older `vars.json`-style definitions into the current profile format.

- Improved **Prepar3D v5** SimConnect handling and bundled compatibility support for more reliable telemetry polling.

### Device management and rules

- Improved device metadata resolution for **alternate hardware modes**, including **5-Way Mode** on **Control Panel #3** and composed **CDT-AEROMAX** joystick identities.

- Added a rule-editor action to **fix the selected rule LED output device** when a profile still points at a stale or missing device entry.

- Refined **Shift Link** localization and UI wording, including clearer **AND / OR** labels in routing conditions.

### Settings, auth, and documentation

- Refreshed **Settings → Transports** and **Settings → Updates** layouts for clearer simulator setup and update checks.

- Regenerated bundled **English and Russian** user guides and Quick Start PDFs to match the latest documentation.
