5.0.1-kde-test (KDE integration verification)

Pre-release built from the kde branch (tip 04bda75) to validate the KDE-integration work. Not for end users.

wiRedPanda 5.0.1

🐛 Bug Fixes

• Translation regression: fixed a bug introduced in 5.0.0 where only English was available in the language menu, even on systems configured for other languages. All 39 translations now load correctly on desktop, WASM, and every platform.

wiRedPanda 5.0.0

🎯 For Users

🚀 New Features

• 4-state logic: Signals now carry four states — Unknown, Inactive, Active, and Error — for more accurate simulation feedback
• Embedded ICs: ICs can be stored directly inside .panda files, making circuits self-contained and easier to share
• SystemVerilog export: Export circuits to SystemVerilog with hierarchical IC support
• Enhanced Arduino codegen: Improved code generation with IC support, board selection, and testbench validation
• Variable-size Mux/Demux: Multiplexer and demultiplexer elements with dynamic input/output sizing
• Wireless Node Tx/Rx: Nodes can operate in wireless transmitter/receiver mode for cleaner layouts
• Per-state appearance editing: Multi-state elements support editing appearances for each state
• Auto-update notifications: Checks for new releases from GitHub and notifies users
• Auto-migration: Automatic file format migration with versioned backup
• System theme: Follows the OS color scheme
• Buzzer improvements: Arbitrary frequency (20–20,000 Hz) and volume control
• Clock slider: Labeled slider for precise clock phase delay adjustment

⚡ Performance

• Batched grid rendering for significantly faster scene drawing
• Cached audio device detection on Windows
• Inlined simulation hot paths and pre-filtered IC boundary elements
• Throttled visual updates to monitor refresh rate during simulation
• Lightweight labels, cached pixmaps, and deferred font loading

🐛 Bug Fixes

• Fixed crashes when working with multiple tabs simultaneously
• Fixed IC loading failures across different operating systems
• Fixed macOS crash with Truth Table elements on Qt 6
• Fixed undo/redo instability when splitting connections or morphing elements
• Fixed inconsistent simulation behavior between runs and incorrect clock timing on resume
• Fixed Save As opening the target file instead of saving
• Fixed viewport jumps when dragging elements
• Fixed numerous IC-related issues: cycle detection, port numbering, embedded blob corruption, port metadata ordering
• Fixed flip horizontal doing nothing due to inverted condition check
• Fixed flip horizontal and vertical producing identical results on asymmetric elements (e.g., D-latch) by using true mirror transforms instead of rotation
• Fixed element icons not updating on theme switch
• Fixed Examples path resolution for AppImage/macOS bundles
• Fixed WebAssembly issues: persistent settings, bundled fonts for non-Latin scripts, dark/light theme detection, and preloaded examples

🔧 For Developers

🏗️ Architecture

• Complete simulation overhaul from boolean to four-state signal model
• New ICRegistry system supporting both embedded and file-based IC workflows
• Per-scene element ID management; removed global ID registry
• Eliminated GlobalProperties class; migrated to Application, Scene, and RecentFiles

• Unified external file dependency management via GraphicElement::externalFiles()
• Self-registering ElementMetadata with compile-time validated declarations
• Tarjan's SCC-based feedback detection for simulation priority ordering
• Separated file format version from application version

📦 Build & Infrastructure

• Qt 6.2+ required — dropped Qt 5 support
• CMake presets for all build variants (debug, release, coverage, sanitizers)
• Unity build + PCH for faster compilation
• Migrated to Ubuntu 24.04 LTS DevContainer with Qt 6.11.0
• Sentry improvements: breadcrumbs, user ID, tags, and deduplication
• Security-hardened GitHub Actions workflows with Dependabot
• AppImage now bundles glibc and all dependencies, removing previous distro compatibility limitations
• Windows 64-bit only

🧪 Testing

• Expanded from 36 tests to 1,722 tests in a single unified binary
• GUI-level test suites for MainWindow, BeWavedDolphin, and FileDialogProvider (developer-only, excluded from CI)
• Backward compatibility regression suite for .panda file formats
• Parallel CTest execution

📚 Code Quality

• PascalCase standardization for all source files
• Scene, serialization, and module decomposition into single-responsibility components
• Procedural audio generation replacing embedded WAV assets
• Full Doxygen documentation setup
• Updated translations for 39 languages

📁 File Format

• V4.4: Wireless node mode
• V4.5: File-level metadata and embedded IC blob registry
• V4.6: Metadata map consolidation
• V4.7: QMap-based connection serialization
• V5.0: File format version bump for 5.0.0 release
• Auto-migration from older formats with versioned backups
