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 */ ]
}
