Improvements and Optimizations

• CSS and JavaScript Fixes: Various fixes and improvements to styling and scripting, including logo fixes and example corrections.

Documentation Updates

• Updated SetupAndWiFi.md with clarified captive portal descriptions and added details on IP address and mask configuration.
• Added an image to the Websocket Echarts README for better visual reference.
• General README updates and documentation enhancements.

Other Changes

• Merged pull requests from contributors for ESP32-P4 fixes and random seed improvements.
• Minor internal commits preparing for release and code maintenance.

FSWebServer 3.2.0

v3.2.0

Config Schema v2

The config.json format has been updated to a hierarchical structure:

• Old format (v1): flat keys at root level
• New format (v2): structured with _version, _meta, _state, _assets, and sections

Existing v1 configurations are automatically migrated at runtime. No manual intervention required.

New structure:

{
  "_version": "2.0",
  "_meta": {
    "app_title": "Your App",
    "logo": "/config/logo.svg",
    "port": 80,
    "host": "myserver"
  },
  "_state": {},
  "_assets": {
    "css": [],
    "js": [],
    "html": []
  },
  "sections": [ /* application options */ ]
}

Improvements

• Setup/UI: Major updates to /setup and /edit pages with refined styling and asset handling
• WiFi Service: Enhanced connection diagnostics and STA network configuration logging
• WebSocket: Improved random seeding on ESP32 using esp_random() for better security
• Captive Portal: Optimized flow and better IP configuration handling

WebSocket Telemetry Dashboard example

Added new websocketEcharts example with a live real-time dashboard:

• Displays heap memory, max block size, and WiFi RSSI
• Built with ECharts 5 for smooth animated charts
• Available in both examples/ and pio_examples/ directories
• Supports multiple themes (Aurora, Sunrise, Mono)

Removals

• highcharts example has been replaced by the new websocketEcharts example

FSWebServer 3.1.0

Security and WiFi Management Enhancements

This release introduces significant improvements to WiFi credential management, password security, and user interface, making the server more reliable and easier to use on ESP32/ESP8266 devices.

Key Improvements

WiFi Password Encryption: Passwords are now encrypted using AES-256-CBC (with hardware support on ESP32) to protect saved credentials.
Dedicated WiFiService Class: Introduction of a centralized class to handle scanning, connections, captive portal, and watchdog. Improves connection reliability and allows smarter management of multiple networks (up to 5 WiFi credentials).

Advanced Credential Management:

Support for multiple SSIDs with automatic selection based on the strongest signal.
Improved UI for managing credentials (add, edit, delete).
Ability to save WiFi credentials persistently with encryption.

Refreshed User Interface:

Unicode icons instead of SVG to reduce size.
Improvements to mobile responsiveness.
Added credential management with tabs for multiple networks (if applicable).

###Updated Documentation.
Added sections dedicated to password encryption and WiFi management in the README.
Integrated Setup Page Refactoring: Complete overhaul of app.js, creds.js, style.css, and all.htm to support new features.
Compatibility: Maintains backward compatibility with version 3.0.0, but some sketches may require minor updates to leverage new APIs.
Compatibility Notes

⚠️ This is a release with minor breaking changes for WiFi credential management. Existing sketches should continue to work, but testing reconnection and encryption is recommended.

Benefits:
✅ Increased security for WiFi credentials
✅ Better connection reliability
✅ More intuitive and mobile-friendly UI
✅ Better support for multiple networks

FSWebServer 3.0.0

This major release introduces significant architectural changes to improve flexibility and reduce dependencies.
The most notable change is the removal of ArduinoJson as a required dependency, which has been replaced with a lightweight, custom JSON handling implementation based on cJSON.

Custom JSON Handler Implementation:

• Introduced a new lightweight FSWebServer::Json class that wraps the cJSON library
• Provides a simplified API for JSON serialization and deserialization without external heavy libraries
• Reduced memory footprint and improved performance on resource-constrained ESP devices
• Users no longer need to include #include <ArduinoJson.h> in their sketches

Class Organization & Restructuring

• Reorganized core library classes for better maintainability and logical separation of concerns
• Improved namespace organization within FSWebServer namespace
• Enhanced code modularity to support cleaner integrations

API Updates

• JSON operations now use the new FSWebServer::Json class instead of ArduinoJson's JsonDocument, JsonArray, and JsonObject types
• Internal JSON handling methods have been updated throughout the library
• WebSocket and API response generation now utilize the custom JSON implementation

Examples have been updated to demonstrate the new API.

Benefits:
✅ Reduced library dependencies and firmware size
✅ Faster compilation times
✅ Better compatibility with lean/minimal builds
✅ Improved ESP8266/ESP32 memory efficiency
✅ Simplified JSON handling for common use cases

Compatibility Notes:
⚠️ This is a breaking change - Projects using v2.0.10 might require code updates to migrate to v3.0.0.
The old ArduinoJson API is no longer supported internally, though users can still include ArduinoJson separately if needed for their own sketches.
