[calendar] Your are using the deprecated config values 'colo

Error message

[calendar] Your are using the deprecated config values 'coloredSymbolOnly'. Please switch to 'coloredSymbol' & 'coloredText'!

What it means

The calendar module warns when the legacy `coloredSymbolOnly` option is set. That single boolean has been superseded by the pair `coloredSymbol` and `coloredText`; the module maps coloredSymbolOnly to coloredText=false, coloredSymbol=true for compatibility, but the option is deprecated and will be removed.

Solutions

1. Replace `coloredSymbolOnly: true` with `coloredSymbol: true` (and omit coloredText, or set coloredText: false)
2. Ensure colored is not also set, which would override these values
3. Re-check the calendar module documentation for the current option names after upgrading

Example fix

// before
config: { coloredSymbolOnly: true }
// after
config: { coloredSymbol: true }

if ("coloredSymbolOnly" in calendarConfig) {
  console.warn("coloredSymbolOnly is deprecated: use coloredSymbol: true (and coloredText: false if needed)");
}

function usesDeprecatedColoredSymbolOnly(cfg) {
  return typeof cfg === "object" && cfg !== null && "coloredSymbolOnly" in cfg;
}

When it happens

Trigger: config.js calendar module config contains `coloredSymbolOnly: true`, hitting the Log.warn at defaultmodules/calendar/calendar.js:102 in start().

Common situations: Configs written when coloredSymbolOnly was introduced to show only colored symbols; copy-pasted example configs from older docs or forum posts after upgrading MagicMirror.
