v4.2.0

Minor Changes

• #697 b8dd9e8 Thanks @samuelwei! - add support for eslint v10

• #689 bb9e1df Thanks @Jerc92! - Add valid-plural-forms rule to validate plural form counts per locale

  This rule enforces that plural messages have the correct number of forms for each locale, helping prevent runtime errors when vue-i18n's pluralRules function returns an out-of-bounds index.

  • Defaults to [2, 3] for all locales (matches vue-i18n's built-in pluralization)
  • Use pluralFormCounts to configure locale-specific overrides
  • Arrays allow multiple valid counts (e.g., [2, 4] for languages supporting both binary and full pluralization)

  Configuration example:

  {
    "@intlify/vue-i18n/valid-plural-forms": [
      "error",
      {
        "pluralFormCounts": {
          "sl": [2, 4],
          "sr-latn": [2, 3]
        }
      }
    ]
  }
