HamClock-Next v1.0.0 B01 – Security, Stability & Cross-Platform Maturity

This release represents a three-day intensive focus on production-grade hardening, UI unification, and cross-platform monitoring consistency. We have transitioned from feature completion to system-wide stability and security.

Security & Stability Hardening

We've implemented professional-grade security controls to ensure HamClock-Next is safe for internet-exposed or complex network environments:

• Private IP Gate: The integrated web server now includes a safety gate to prevent accidental exposure on public IP addresses.
• SSRF Protection: Added strict input validation for all URL-based requests to mitigate Server-Side Request Forgery risks.
• Memory Caps: Implemented rigid limits for the DX Cluster spot cache and NetworkManager to prevent runaway memory usage during peak solar activity.
• RPi 3B OOM Fix: Optimized texture loading and downscaling logic to prevent Out-Of-Memory crashes on legacy hardware like the Raspberry Pi 3B.

Visual & UI Unification

A major "polish pass" has been completed to make HamClock-Next look and feel like a single, cohesive application:

• Unified Widget Titles: Every panel (Contest, Band Conditions, SDO, etc.) now uses a standardized, theme-aware title bar style with consistent padding and typography.
• Anti-Aliased Weather: Restored and enhanced the visibility of weather contour lines and wind arrows with high-quality anti-aliasing.
• EME Planning Tool: Fully refined the layout of the EME tool, resolving text overlaps and improving alignment for high-density data.
• Dynamic SDO Sizing: Resized the SDO sun image to maximize space for widget navigation and selection.

Cross-Platform System Intelligence

The "System Info" widget is now a first-class citizen on all platforms:

• Universal Monitoring: Implemented platform-specific backends for CPU % tracking and RAM usage for Linux, macOS, and Windows.
• Windows IP Retrieval: Integrated GetAdaptersAddresses for reliable local IP detection on Win64.
• WASM Stability: Resolved critical build blockers for the browser-based version, including JS syntax errors in the IDBFS mount logic and POSIX header conflicts.

Build System Optimization

• Master Build Script: Introduced scripts/build-all.sh to orchestrate multi-platform builds in a single pass.
• Extreme Disk Space Recovery: Implemented a "Move and Purge" pattern across all build scripts. After successfully generating installers (DEB, RPM, DMG, EXE), the scripts now purge ~30GB of intermediate object files and CMake caches.
• Win64 Portability: Resolved all format specifier warnings and header conflicts for the MinGW-w64 toolchain.
