2.0.2: Bugfixes & UI fixes

on GitHub

✨ Features

Performance

• Add direct I/O bypass for Linux (O_DIRECT), macOS (F_NOCACHE), and Windows (FILE_FLAG_NO_BUFFERING) to reduce memory pressure during writes
• Add zero-copy ring buffer for data transfer between download and write threads, reducing CPU overhead
• Add asynchronous cache file writer to overlap download and disk I/O operations
• Dynamically adjust write queue depth based on available system memory, tuned for more aggressive performance
• Add sequential read hints (FADV_SEQUENTIAL, F_RDAHEAD) during verification for better prefetching
• Track detailed performance metrics for network, decompression, and write phases
• Use Windows IOCTLs (IOCTL_DISK_DELETE_DRIVE_LAYOUT) for faster disk preparation instead of diskpart
• Add performance data analysis tool for debugging slow writes (Press CTRL + SHIFT + P, save the JSON, attach to a new Issue).

Drive Handling

• Switch drive polling from fixed 1-second interval to adaptive mode (fast during selection, paused during writes)
• Fix NVMe namespace detection on Linux to correctly identify NVMe drives by parsing /sys/class/nvme/
• Suppress Windows "Insert a disk" error dialog when accessing empty removable drives
• Fix macOS APFS volume handling to correctly identify child partitions
• Allow virtual disks to be treated as 'system' drives on Windows & Linux (macOS was supported from 2.0.0)

User Interface

• Add password field component with show/hide toggle button
• Add type-to-search in combo boxes with backspace support to delete characters
• Add Enter key to open combo box dropdown when focused
• Show device and OS names with tooltips when text is truncated
• Restructure countdown timer before write confirmation dialog can be accepted
• Fix bottom padding in write confirmation dialog
• Reintroduce multiple SSH key support

Accessibility

• Add proper focus order and keyboard navigation for screen readers across all dialogs
• Move accessibility description properties to centralized form label component

macOS

• Add file type filter popup to native save dialogs (matching Finder behavior)
• Request location permission asynchronously to avoid blocking the UI when detecting WiFi networks
• Add dark mode, tinted and clear Liquid Glass icon variants using Icon Composer for proper menu bar appearance

Linux

• Fix X11 authorization when running AppImage as root via xhost and proper XAUTHORITY handling
• Install scalable SVG icon instead of fixed-size PNG for better HiDPI support

Windows

• Migrate file dialogs from legacy GetOpenFileName API to modern IFileDialog COM interface
• Fix file dialog filter string requiring double-null termination
• Fix scroll direction on ImComboBox

Customization

• Allow SSH public key authentication without requiring a username/password to be set
• Fix missing user creation block when not enabling SSH

Networking

• Add automatic fallback from HTTP/2 to HTTP/1.1 after repeated failures
• Log HTTP protocol version used on successful downloads
• Skip error dialogs when user cancels download mid-transfer
• Properly close file handles when operations are cancelled

Other

• Add file logging support (--log-file command line argument)
• Re-use ring buffer memory for SHA256 verification instead of allocating new buffers
• Validate init_format field in OS list JSON and log warnings for invalid entries
• Extract clean version string (X.Y.Z) for telemetry instead of full build string
• Add privilege escalation support for elevatable application bundles

🐛 Bug Fixes

• Fix SSH key file dialog filter on Windows (was passing list instead of string)
• Fix Italian translation inconsistencies
• Fix icon installation path for Linux desktop integration
• Fix cloud-init user-data generation for Pi Connect configuration
• Remove O_SYNC flag from file operations (was causing unnecessary performance penalty)
