v1.0.4.4

Fixes

• GUI startup crash on systems without a resolvable default font (#2, third attempt) — bundle Inter directly as a project asset (WireView2/Assets/Fonts/Inter-Regular.ttf) and reference it via the avares:// URI scheme that we already use for icon and background images. Drops the Avalonia.Fonts.Inter NuGet dependency entirely so the font no longer travels through fonts:Inter#Inter resolution, which appears to be where 1.0.4.2/1.0.4.3 still failed on Ubuntu 25.10.

The bundled Inter font is licensed under SIL OFL 1.1.

v1.0.4.3

Fixes

• GUI startup crash on systems without a resolvable default font (#2, second attempt) — the previous fix in 1.0.4.2 only registered the bundled Inter font; Avalonia was still calling the platform default-font lookup which fails on Ubuntu 25.10. This release explicitly sets FontManagerOptions.DefaultFamilyName so $Default resolves to the bundled Inter font, bypassing platform font discovery entirely.

v1.0.4.2

Fixes

• GUI startup crash on systems without a resolvable default font (#2) — Avalonia was hitting Could not create glyphTypeface. Font family: $Default on fresh installs (e.g. Ubuntu 25.10). The app now registers the bundled Inter font as the default, so startup no longer depends on fontconfig resolving a system default.
• App preventing system shutdown / logout (#1) — the close-to-tray handler was vetoing OS-driven close requests, which session managers reported as "App is preventing shutdown". Close-to-tray now only triggers when the user explicitly closes the window; OS shutdown / session-end requests pass through.

v1.0.4.0

What's New

• Config V3 support: Full support for config version 2 (UiConfigStructV2) — ARGB theme colors, background/fan bitmaps, display inversion
• Config version detection fix: Reads actual config version from device instead of guessing from firmware version
• Theme preset system: 6 Thermal Grizzly presets (TG1–TG6) + Custom, with auto-detection when loading config
• Close-to-tray: Window hides on close instead of exiting — reopen from tray icon
• Performance optimization: Chart axis updates are paused when the window is hidden/minimized
• AutoStart sync on startup: App syncs its auto-start setting with the OS state at launch

v1.0.3.2

Bug fixes

• ReadExact: Fixed Environment.TickCount wrap-around causing spurious timeouts after ~24.9 days of uptime. Replaced with TickCount64.
• SendData, WriteConfig, SpiFlashReadBytesAsync: Serial port is now always closed on exception via try/finally. Previously, a timeout or IO error mid-operation would leave the port open, hanging all subsequent operations.

See v1.0.3.1 and v1.0.3.0 for previous changelogs.

v1.0.3.1

Bug fixes

• DeviceLogParser: Fixed inverted switch logic that could cause unknown datalog entry types to be incorrectly processed instead of skipped (matches original upstream behavior)
• WriteConfig: Added offset bounds check to prevent silent byte truncation for configs exceeding 255 bytes
• HwmonDevice: Added socket response length validation (max 1024 bytes) to prevent memory exhaustion from malformed daemon responses
• HwmonDevice: Added config version validation before unmarshaling — unknown versions now return null instead of blindly deserializing

See v1.0.3.0 for the full hwmon + daemon integration changelog.

v1.0.3.0

What's new

hwmon + daemon integration

The app now fully supports the wireview-hwmon kernel module and daemon as an alternative to direct serial communication. When the kernel module is loaded, the app automatically:

• Reads sensor data from /sys/class/hwmon/ (voltage, current, power, temperature)
• Connects to the wireviewd daemon socket (/run/wireviewd.sock) for full device control

All features work through the daemon — configuration read/write, fault clearing, screen commands, device info, and NVM operations. If the daemon is not running, the app still displays sensor data in read-only mode. If the kernel module is not loaded, the app falls back to direct serial as before.

wireviewctl CLI tool

The wireview-hwmon project now also includes wireviewctl, a CLI tool for scripting device commands and reading sensor data from the terminal. Supports info, sensors, clear-faults, read-config, write-config, screen, nvm, build, and bootloader commands.

Connection modes

Mode	Requirements	Features
Direct serial	Device connected via USB	Full control (default)
hwmon + daemon	wireview-hwmon module + wireviewd	Full control + system sensor integration
hwmon only	wireview-hwmon module (no daemon)	Read-only sensor data

This means you can now have both the app running and sensor data available to sensors, Grafana, btop, conky, and other monitoring tools simultaneously.
