v25.10.10

Compare Source

• feat: suppress support notice automatically in production environments (NODE_ENV=production)

v25.10.9

Compare Source

• feat(types): export SelectorParam<Ns, KPrefix> helper type — a stable, readable alternative to Parameters<TFunction<Ns>>[0] for typing selector function props 2414

v25.10.8

Compare Source

• fix(types): reorder TFunctionSelector overloads so Parameters<TFunction> resolves to the general selector signature instead of the branded SelectorKey type 2412

v25.10.7

Compare Source

• feat(types): support typescript 6 to address i18next/react-i18next#1910

v25.10.6

Compare Source

• feat(types): support typescript 6 to address i18next/react-i18next#1910

v25.10.5

Compare Source

• feat(types): selector functions as keyPrefix in getFixedT now provide full type-safe key narrowing — the returned t function is scoped to the prefix subtree 2367

v25.10.4

Compare Source

• feat(types): exists() is now a type guard that narrows the key to SelectorKey, so a validated key can be passed directly to t() 2364

v25.10.3

Compare Source

• check also for I18NEXT_NO_SUPPORT_NOTICE env variable

v25.10.2

Compare Source

• feat(types): keyFromSelector is now type-safe — the selector callback is constrained against your resource definitions, catching invalid keys at compile time. Supports optional ns and keyPrefix options for non-default namespace/prefix contexts 2364

v25.10.1

Compare Source

• feat: suppress support notice automatically in production environments (NODE_ENV=production)

v25.10.0

Compare Source

• feat(types): keyFromSelector now returns a branded SelectorKey type that t() accepts directly, enabling pre-computed and reusable translation keys 2364
• feat: support selector syntax for keyPrefix in getFixedT and per-call options 2367
• feat(types): interpolation values are now automatically typed based on built-in format specifiers — {{val, number}} requires number, {{val, datetime}} requires Date, {{name}} requires string, etc. Custom formatters can be typed via interpolationFormatTypeMap in CustomTypeOptions 2378
• fix(types): FilterKeys in selector mode now preserves non-context, non-plural leaf keys when context is provided, fixing incorrect type narrowing when combining returnObjects: true with context 2398

v25.9.0

Compare Source

• feat(types): selector API now enforces { count: number } when a key resolves to plural forms 2373
• fix(types): string unions with invalid members are now correctly detected as type errors when used as context option 2172

v25.8.20

Compare Source

• fix: getFixedT() selector now resolves namespaces against the effective ns rather than the global init options 2406

v25.8.19

Compare Source

• fix: selector API namespace resolution regression for single-string ns and primary namespace in array 2405. Reverts the broad namespace-prefix rewrite from v25.8.15 and replaces it with a targeted fix that only rewrites paths starting with a secondary namespace in a multi-namespace array, matching the type-level contract of GetSource

v25.8.18

Compare Source

• improve selector api to accept array of selector functions, analogous to array of keys 2404

v25.8.17

Compare Source

• update deps

v25.8.16

Compare Source

• fix(types): on() method now correctly returns this instead of void, matching the runtime behavior and enabling proper method chaining in TypeScript

v25.8.15

Compare Source

• fix: Selector API unable to resolve namespaces 2402

v25.8.14

Compare Source

• fix: getCleanedCode now replaces all underscores

v25.8.13

Compare Source

• improve support notice shown logic

v25.8.12

Compare Source

v25.8.11

Compare Source

• revert fix: compatibility with moduleResolution bundler (issue 2380) 2381

v25.8.10

Compare Source

• fix(interpolator): guard null matchedDoubleQuotes in nesting option parsing 2395

v25.8.9

Compare Source

• fix(interpolator): escape nestingOptionsSeparator in nesting option parsing 2394

v25.8.8

Compare Source

• types(i18n): add missing toJSON() declaration 2393

v25.8.7

• fix: compatibility with moduleResolution bundler (issue 2380) 2381

v25.8.4

Compare Source

• fix: crashes when backend in backends array has no name property 2386

v25.8.3

Compare Source

• ts: document option to suppress the support message 2385

v25.8.2

Compare Source

• fix: getFixedT() selector now resolves namespaces against the effective ns rather than the global init options 2406

v25.8.1

Compare Source

• fix: selector API namespace resolution regression for single-string ns and primary namespace in array 2405. Reverts the broad namespace-prefix rewrite from v25.8.15 and replaces it with a targeted fix that only rewrites paths starting with a secondary namespace in a multi-namespace array, matching the type-level contract of GetSource

v25.8.0

Compare Source

• fix: TFunctionReturn fallback 2360
• chore: added a console.info support notice regarding the open-source sustainability of the i18next ecosystem. (Note: This can be easily suppressed via showSupportNotice: false, globalThis, or environment variables. See the FAQ for details on how to disable it).
