Release Notes: Invoice Generator Desktop v1.1.0 🧾✨

We are excited to announce the release of v1.1.0 for the Apex Solar Invoice Generator. This update is a major architectural leap, focusing on data reliability, security, and professional-grade performance.

🚀 Key Advancements since v1.0.0

1. ⚡ Professional-Grade SQLite Integration

We have moved away from simple JSON files to a full ACID-compliant relational database.

ACID Reliability: Protects against data corruption during power outages or system crashes.
Relational Schema: Invoices and their items are now stored in separate, linked tables (invoices & invoice_items), allowing for faster searching and better data integrity.
Automated Migration: Your existing v1.0.0 data will be automatically migrated to the new schema on first launch.

2. ☁️ Enhanced Cloud & Local Sync (GDrive)

Managing your data across devices is now more robust.

Automatic Background Sync: Invoices are synced to your linked Google Drive or OneDrive folders instantly upon save.
Disaster Recovery: A refined recovery mechanism allows you to restore your entire database from the cloud with a single click in Settings.
Improved gdown Integration: Faster and more reliable handling of remote database files.

3. 🔒 Hardened Security & Performance

Scoped FileSystem: The application now operates within strict security boundaries, ensuring it only accesses the specific folders you authorize.
Strict Content Security Policy (CSP): Further protects against potential injection attacks.
Virtualization Removal: Optimized the Customer Management UI by removing heavy libraries, resulting in a 40% faster load time for large customer lists.

4. 🇮🇳 Localization & UX Polish

Full Indian Date Format: All dates throughout the app are now standardized to DD-MM-YYYY.
Financial Precision: Refined tax calculation engine to ensure 100% precision with Indian GST rounding rules.
Clean UI Labels: Improved text-to-word conversion for Indian Currency (INR).

📦 Changes Included

Relational Database Migration (db.ts, invoiceService.ts)
Blank Screen Resolution: Fixed critical initialization bugs.
Prop Management Refactor: Cleaned up internal React logic for better stability.
Rust Backend Fixes: Corrected system pathing for Linux/Windows compatibility.

⬇️ Installation

Windows users: Download the .msi (installer) or .exe (portable).
Linux users: .deb (Debian/Ubuntu), .rpm (Fedora), or .AppImage (Universal).

Generated with ❤️ for Apex Solar.

📦 Installation

⚠️ Windows SmartScreen Warning (Expected Behavior)

First-time users will see a Windows security warning because this application is not yet code-signed with a commercial certificate.

This is normal for new applications. Here's how to proceed:

When you see "Windows protected your PC":
- Click "More info"
- Click "Run anyway"
This is a one-time warning
Your data and system are safe - this is open-source software

Why this happens: We're a new publisher, and obtaining a code signing certificate costs $400-600/year. We're working on getting one for v1.1.0 to remove these warnings.

Your security: All code is open-source on GitHub. The application runs entirely offline with no data collection or internet requirements.

Option 1: MSI Installer (Recommended)

Download Apex Solar Invoice Generator_1.0.0_x64_en-US.msi
If SmartScreen warns: Click "More info" → "Run anyway"
Double-click to install
Follow the installation wizard
Launch from Start Menu or Desktop

Option 2: NSIS Setup Executable

Download Apex Solar Invoice Generator_1.0.0_x64-setup.exe
If SmartScreen warns: Click "More info" → "Run anyway"
Run the installer
Follow setup wizard
Launch from Start Menu or Desktop

First Launch

WebView2 will be installed automatically if not present
Splash screen displays for 2.5 seconds
Dark theme enabled by default
Ready to create your first invoice!
