API Changes

This section documents version-specific API changes — prioritize recent major/minor releases.

• DEPRECATED: Legacy API mode — deprecated in v11 for Composition API preference; scheduled for removal in v12 source

• DEPRECATED: Custom Directive v-t — deprecated in v11 due to limited optimization benefits in Vue 3; scheduled for removal in v12 source

• BREAKING: tc and $tc — dropped in v11 for Legacy API mode; use pluralization support in t and $t instead source

• NEW: Vue 3 Vapor Mode — added compatibility for Vue 3 vapor mode in v11.2.0 source

• BREAKING: JIT Compilation — enabled by default in v10 to solve CSP issues and support dynamic resources source

• BREAKING: $t and t Signatures — Legacy API mode signatures changed in v10 to match Composition API mode; positional locale args now require options object source

• NEW: Generated Locale Types — v10 adds support for extending locale types via GeneratedTypeConfig for better TypeScript inference source

• BREAKING: Modulo % Syntax — named interpolation using modulo syntax dropped in v10; use standard {} interpolation source

• BREAKING: vue-i18n-bridge — dropped in v10 following Vue 2 EOL source

• BREAKING: allowComposition Option — dropped in v10; was previously used for Legacy to Composition API migration on v9 source

Also changed: petite-vue-i18n GA v10 · Configurable $i18n type new v11.1.0 · mode property deprecated v11 · tm accepts DefineLocaleMessage key type v11.0.0 · Part options support $n & $d new v11.1.4

Best Practices

• Prefer Composition API mode (legacy: false) for all new projects — Legacy API mode is deprecated in v11 and will be removed in v12 source

• Use t() function or <i18n-t> component over the v-t directive — the directive is deprecated in v11 and lacks IDE support for key completion source

• Define global resource schemas using DefineLocaleMessage, DefineDateTimeFormat, and DefineNumberFormat interfaces — enables automatic type inference and key completion in useI18n without passing type parameters
